You pull a 12-fiber loose-tube cable into a building and open the jacket. Inside you find twelve 250 µm coated fibers — each just a 125 µm glass strand in a thin layer of colored coating, with no strength member of its own. You cannot plug those into anything, and you cannot leave them exposed. A fiber optic fan-out kit is the small, inexpensive hardware set that turns that bundle of bare fibers into twelve protected, color-coded legs ready for connectors.
Quick answer: A fiber optic fan-out kit (also called a furcation kit) is a field-installable hardware set that separates the 250 µm coated fibers of a loose-tube cable and protects each one in a 900 µm tight-buffered tube, so the fibers can be connectorized directly. Use one when you terminate loose-tube cable in the field without fusion splicing. If the cable is already tight-buffered (900 µm) distribution cable, you do not need a fan-out kit.
By the BWNFiber Engineering Team. Last updated: 2026-08-25.
If you only remember five things:
- Fan-out kits are for loose-tube cable with 250 µm fibers. Tight-buffered distribution cable already has 900 µm fibers and does not need one.
- A fan-out kit contains no connectors. It protects fibers; you still terminate or splice afterwards.
- A fan-out kit is not a breakout cable assembly. The kit is field hardware; the assembly is a factory-made cable with jacketed legs and connectors.
- Match the kit to your fiber count (6 or 12 are standard) and leg length (25 in or 36 in are the common options).
- Follow the TIA-598 color code when you load fibers into tubes. Getting the order wrong means re-doing the termination.

What Is a Fiber Optic Fan-Out Kit?
A fiber optic fan-out kit — also called a furcation kit — is a set of hardware used at the end of a multi-fiber loose-tube cable. The kit separates the individual 250 µm coated fibers from the buffer tube and protects each fiber inside its own color-coded 900 µm tube. Once fanned out, each leg is strong enough to handle during connector termination or fusion splicing.
A typical fan out kit for fiber contains a furcation block that anchors the cable, color-coded 900 µm tubes that become the legs, a housing for strain relief, and consumables like epoxy and labels. The anatomy section below breaks down what each part does.
You will also see the same hardware sold as a fiber fan out kit, a buffer tube fan-out kit, or a fiber breakout kit — at some vendors simply a “breakout kit,” and in UK catalogs a “fibre breakout” kit. The naming is not standardized, which causes real ordering mistakes. The next section untangles the terms.
One more term worth defining here: a fiber breakout box is not a kit at all. It is an enclosure mounted at the point where a high-count cable breaks out into smaller legs, giving the fan-out point mechanical protection and slack storage. Kits protect fibers; boxes protect the whole transition. Some outdoor installations use both.
Fan-Out Kit vs Breakout Kit vs Breakout Cable Assembly
These three terms are mixed up constantly — in supplier catalogs, in project specs, and on purchase orders. They are three different things:
| Item | What it is | Connectors included? | Where it is made | Typical buyer |
|---|---|---|---|---|
| Fan-out kit / furcation kit | Field hardware: block + 900 µm tubes + housing | No | Installed in the field onto existing cable | Installers, contractors |
| Breakout kit | Heavier-duty fan-out variant, often with 2.0 mm legs or an enclosure-style housing | No | Field | Installers, contractors |
| Breakout cable assembly | Factory-built cable with jacketed (2.0/3.0 mm) sub-units, connectors pre-installed | Yes | Factory | Network designers, buyers |
Two practical consequences:
- Vendor naming is not consistent. Corning sells “Buffer Tube Fan-Out Kits” in 6- and 12-fiber versions with 25-inch or 36-inch legs. AFL sells “fanout kits.” Panduit sells a “fiber termination fan-out kit.” OCC sells a “Forge Fan-Out Kit.” Always read what the legs are made of (900 µm vs 2.0 mm) rather than relying on the product name.
- A breakout assembly replaces the kit question entirely. If you order a pre-terminated fiber optic cable or a factory fiber cable assembly with breakout construction, the fan-out work is done at the factory under controlled conditions, with tested connectors already attached. The kit is the field-installable answer when the cable is already in the ground, in a duct, or on a reel you own.
Boundary note: MPO breakout and harness assemblies — where one MPO connector fans out to multiple duplex LC legs — are a different product family used in parallel optics. Those are covered in our MPO cabling section, not in this guide.
The 250 µm Rule: When a Cable Needs a Fan-Out Kit
Direct answer: only loose-tube cable with 250 µm coated fibers needs a fan-out kit. Tight-buffered distribution cable (900 µm) and breakout-style cable with jacketed sub-units can be terminated directly, without any kit.
The single most important selection rule is about the cable you already have:
| Cable construction | Fiber coating | Needs a fan-out kit? |
|---|---|---|
| Loose-tube cable (OSP, duct, aerial; fibers float in gel or dry water-blocking inside a buffer tube) | 250 µm | Yes — 250 µm fibers are too fragile to connectorize directly |
| Tight-buffered distribution cable (indoor, riser/plenum) | 900 µm | No — fibers are already 900 µm and can be terminated directly |
| Breakout-style cable (each fiber in its own 2.0/3.0 mm sub-jacket) | 900 µm + sub-jacket | No — sub-units are already connector-ready |
The logic is simple. A 250 µm fiber is a 125 µm glass strand with a thin colored coating. It survives inside a gel-filled tube because the tube protects it. The moment you strip the tube away, that fiber has almost no crush or bend protection. A fan-out kit re-protects each fiber with a 900 µm tight buffer so a technician can cleave it, insert it into a connector, or place it in a splicer without breaking it.
The common mistake we see: a buyer orders fan-out kits for an indoor distribution cable “because the cable has 12 fibers.” Fiber count is not the trigger — coating diameter is. Check the cable datasheet for “250 µm” or “loose tube” before you order kits.

Figure 1: A fan-out kit clamps to the cable jacket, re-protects each 250 µm fiber in a 900 µm tube, and closes inside a strain-relief housing.
Inside the Kit: Anatomy and Color Coding
A fan-out kit is simple hardware, but every part has a job:
- Furcation block / plug: the Y-shaped or cylindrical transition piece. The buffer tube enters one side; the individual 900 µm legs exit the other. It anchors to the cable jacket with screws, crimp, or epoxy depending on the design.
- 900 µm tubes: the legs themselves. Color-coded so each leg maps to a fiber position.
- Housing / shell: covers the block, provides bend protection and a pulling-safe profile, and gives you a surface for a label.
- Strain relief: boot or clamp that transfers pull force to the cable jacket, never to the fibers.
TIA-598-D fiber color order
Most 6- and 12-fiber kits ship tubes in the standard color sequence. Load fibers in this order and your legs will match every patch panel, cassette, and test report in the link:
| Position | Color | Position | Color |
|---|---|---|---|
| 1 | Blue | 7 | Red |
| 2 | Orange | 8 | Black |
| 3 | Green | 9 | Yellow |
| 4 | Brown | 10 | Violet |
| 5 | Slate | 11 | Rose |
| 6 | White | 12 | Aqua |
If your cable’s buffer tube uses the same TIA-598 order (most do), fiber 1 in the tube goes into the blue leg, fiber 2 into orange, and so on. Document the mapping anyway — a photo of the open block before you close the housing has saved more than one troubleshooting session.
Three Ways to Terminate a Loose-Tube Cable
A fan-out kit is one of three legitimate answers to the same problem. Choosing between them is a labor-and-reliability decision, not a product preference:
| Method | How it works | Skill & tooling | Loss contribution | Best when |
|---|---|---|---|---|
| Fan-out kit + field termination | Kit protects fibers; you install field-installable or epoxy-polish connectors on each leg | Moderate; connector consumables per fiber | Connector IL only (no splice) | Small counts, no splicer on site, repair work |
| Fusion splice + pigtails | Splice each fiber to a factory-polished pigtail inside a tray or closure | Needs fusion splicer and splice tray space | Splice ≈0.01–0.05 dB + connector IL | Permanent outside-plant and FTTH builds — the carrier default |
| Pre-terminated assembly | Factory installs and tests connectors before shipment | Minimal field skill; plan lengths in advance | Factory-tested connector IL | Data centers, ODFs, repeatable rollouts, tight schedules |
Rules of thumb we use in project reviews:
- Have a splicer and a closure? Splice-and-pigtail is usually the most robust and the cheapest per fiber at counts above 12.
- No splicer, low fiber count, one building? Fan-out kit plus field connectors is often the fastest legitimate path.
- Cable not purchased yet, schedule tight, counts repeatable? Skip field work entirely and buy pre-terminated.
Not sure which path fits? Send BWNFiber your cable datasheet and site conditions — our engineers will recommend one of the three, with the reasoning in writing. Ask engineering →

Figure 3: Three legitimate answers to the same cable end — choose on labor profile, not hardware price.
When to Use a Fan-Out Kit
Fan-out kits earn their place in specific, recurring situations:
- OSP cable entering a building. A loose-tube feeder transitions to indoor termination at the entrance facility, and codes typically limit how far an unlisted outside-plant cable may run inside — in North America, often 15 m (50 ft) from the entrance point per NEC for unlisted OSP cable (local codes vary; verify yours). The fan-out point re-protects the fibers right where the jacket ends.
- Direct termination at a patch panel or ODF where splicing is not allowed or no splice tray exists.
- Repair and restoration. A cut cable end needs re-termination now, and the splicer — or a closure — is not on the truck. Dig-ins and storm damage are the classic cases: the first crew on site needs a termination method that does not wait for the splicer.
- Small-count, one-off links where ordering a custom pre-terminated assembly would add procurement time the project does not have.
- Test and lab benches, where raw loose-tube samples need safe legs for repeated connectorization.
If your scenario is high-count, schedule-driven, or repeated across many sites, a factory assembly will almost always beat field work on total installed cost.
How to Install a Fan-Out Kit: 8 Steps
Exact steps vary by kit design — follow the vendor instruction sheet first. This is the sequence we train against for a typical 12-fiber kit:
- Plan leg length and strip point. Mark where the housing will sit. Strip the outer jacket and armor (if present) far enough back to leave full leg length plus working room.
- Expose and cut the buffer tube. Remove the jacket, strength members, and water-blocking. Trim the buffer tube to leave the fibers protruding at the length the kit specifies.
- Clean the 250 µm fibers. Remove gel or flooding compound with an approved cleaner and lint-free wipes. Residue left on the coating causes slip inside the tubes later.
- Fit the furcation block onto the cable. Seat the buffer tube(s) and strength member into the block per the kit’s anchor method — screw clamp, crimp ring, or epoxy. The strength member anchor is what gives the assembly its pull rating; do not skip it.
- Thread each fiber into its 900 µm tube. Follow the TIA-598 color order. Feed gently; a kinked 250 µm fiber is a broken fiber.
- Seat and secure the tubes in the block. Depending on the kit this is a snap-fit, a set screw, or a small epoxy pot. Verify each tube is captured before moving on.
- Close the housing and attach strain relief. Check that no fiber is pinched at the exit point and that the boot bends smoothly.
- Label every leg and record the mapping. Mark each leg with its position or destination, then terminate connectors or splice as planned. Test every leg — power meter for insertion loss, OTDR when you need the trace — before closing up the panel; our loss budget guide covers the method and acceptance limits.

Figure 2: Strip, clean, anchor, thread, secure, close, label, terminate — in that order.
Common Fan-Out Kit Mistakes
- Buying kits for tight-buffered cable. The 250 µm rule above. A distribution cable does not need — and cannot use — a fan-out kit.
- Skipping the strength-member anchor. The fibers then carry the pull load, and the legs start failing weeks later.
- Wrong leg length. 25-inch legs that must reach across a 36-inch tray force tight bends at the block. Measure the routing path, not the straight-line distance.
- Ignoring bend radius at the exit. A 900 µm leg bent hard at the block exit is the classic hidden macro-bend. Keep the exit path gentle.
- Mixing the color order. One swapped pair means two mislabeled fibers at the far end and a confusing afternoon with a VFL.
- Leaving the fan-out point unprotected. A bare block in an open tray gets snagged. Use the housing, a breakout box, or at minimum a protected tray zone.
How to Choose the Right Kit
Five parameters decide the part number:
- Fiber count — 6 and 12 are the standard kit sizes; 24-fiber versions exist but a closure plus pigtails is usually cleaner above 12.
- Cable type compatibility — confirm the kit is rated for loose-tube 250 µm input and check the buffer-tube diameter range the block accepts. Fiber grade does not affect kit fit — G.652.D, G.657.A2, OM3, or OM4 all share the same 250 µm coating; the kit protects the coating, not the glass.
- Leg size — 900 µm legs for connectorization and splicing; 2.0 mm legs (breakout-style kits) where legs need more handling abuse or direct routing.
- Leg length — 25 in (≈0.64 m) and 36 in (≈0.9 m) are the common options. Choose by measuring the actual routing path inside the panel or closure.
- Environment — indoor kits assume a protected tray; outdoor or industrial points need a housing with proper sealing, or the fan-out point should live inside a closure or breakout box. European indoor projects often specify LSZH tube material (and CPR classes on the cable itself) — put the exact requirement on the order.
The standard kit matrix most vendors quote against:
| Fiber count | Leg size | Leg length | Typical kit |
|---|---|---|---|
| 6 | 900 µm | 25 in (≈0.64 m) | Compact wall-mount panels |
| 6 | 900 µm | 36 in (≈0.9 m) | Deeper trays and frames |
| 12 | 900 µm | 25 in (≈0.64 m) | The most-quoted configuration |
| 12 | 900 µm | 36 in (≈0.9 m) | ODFs, closures, long reaches |
| 6 / 12 | 2.0 mm | vendor-specific | Breakout-style kits for direct routing |
And one procurement habit that prevents most mismatches: send the kit supplier the cable datasheet, not just the fiber count.
Fan-Out Kit Pricing Guide
Fan-out kits are low-cost hardware, and price should never be the reason to skip one — the labor it protects is worth far more. As of 2026, typical street pricing runs roughly:
| Kit type | Typical price range (USD) | Notes |
|---|---|---|
| 6-fiber, 900 µm legs | ~$15–$40 per kit | The common patch-panel kit |
| 12-fiber, 900 µm legs | ~$20–$60 per kit | Most-quoted configuration |
| 2.0 mm leg / breakout-style kits | ~$40–$90 per kit | Heavier legs, enclosure-style housings |
| Fiber breakout boxes | ~$30–$150+ | Depends on ports, rating, and material |
Pricing moves with brand, tube material (Hytrel vs PVC vs LSZH), housing quality, and order volume. These ranges are indicative, not quotes — volume pricing for a rollout should be requested against a fixed spec.
Quality Checks and Buyer’s Checklist
Before you accept a kit shipment, and before you close the housing on site:
- [ ] Kit is rated for 250 µm loose-tube input (check the datasheet, not the title)
- [ ] Fiber count and leg length match the routing measurement
- [ ] Tube material suits the environment (LSZH indoors where required)
- [ ] Kit includes a strength-member anchor method
- [ ] Legs are color-coded to TIA-598 and the mapping is documented
- [ ] After termination: every leg tested for continuity and loss before the panel is dressed
- [ ] Supplier can provide consistent part numbering across re-orders
- [ ] Sample kit ordered and checked before the volume order — block fit on your actual cable, tube quality, housing closure, and the instruction sheet
Frequently Asked Questions
What is a fiber optic fan-out kit?
A fiber optic fan-out kit (furcation kit) is a field-installable hardware set that separates the 250 µm coated fibers of a loose-tube cable and protects each fiber in its own 900 µm color-coded tube. The protected legs can then be connectorized or spliced safely. The kit contains no connectors — it only protects and organizes the fibers.
What is the difference between a fan-out kit and a breakout kit?
In most catalogs they are the same class of hardware with different marketing names. Where vendors do distinguish them, “breakout kit” usually means a heavier-duty version with 2.0 mm jacketed legs or an enclosure-style housing, while “fan-out kit” means 900 µm legs. Always compare the leg size and housing on the datasheet instead of relying on the name.
Is a fan-out kit the same as a breakout cable assembly?
No. A fan-out kit is field hardware installed onto a cable you already have. A breakout cable assembly is a factory-built cable with jacketed sub-units and connectors already installed and tested. If the cable is not purchased yet, a factory assembly usually saves labor; if the cable is already installed, the kit is the practical option.
When does a cable need a fan-out kit?
Only loose-tube cable with 250 µm coated fibers needs one. Tight-buffered distribution cable already has 900 µm fibers that can be terminated directly, and breakout-style cable already has jacketed sub-units. Check the cable datasheet for “250 µm” or “loose tube.”
Does a fan-out kit include connectors?
No. The kit protects the fibers so that connectors can be installed afterwards — either by field termination on each leg or by fusion splicing to pigtails. Connectors, epoxy, polishing films, or pigtails are purchased separately.
What is a fiber breakout box used for?
A fiber breakout box is an enclosure installed at the point where a high-count cable breaks out into smaller legs. It protects the fan-out transition mechanically, provides slack storage, and gives a mounting point for labels. It complements a fan-out kit in exposed or outdoor locations rather than replacing it.
What leg length should I choose: 25 or 36 inches?
Measure the actual routing path from the cable entry point to the farthest connector or splice position, following the tray or closure routing guides, then add working slack. 25-inch legs suit compact wall-mount panels; 36-inch legs are the safer choice for deep frames and closures. When in doubt, take the longer leg — excess can be dressed, short cannot.
Can I use a fan-out kit outdoors?
The kit itself is not weatherproof. Outdoor fan-out points should live inside a sealed closure, an entrance cabinet, or a breakout box with a suitable rating. The kit organizes and protects the fibers; the enclosure protects the kit.
How many fibers can one fan-out kit handle?
Standard kits handle 6 or 12 fibers from a single buffer tube. Multi-tube and 24-fiber versions exist, but above 12 fibers a splice closure with factory pigtails is usually the more serviceable design.
How do I terminate loose-tube fiber cable without a fusion splicer?
The standard path is a fan-out kit plus field-installable connectors: the kit re-protects the 250 µm fibers in 900 µm tubes, and mechanical connectors terminate each leg without polishing equipment. For high fiber counts or permanent outside-plant links, bring in a splicer or order a pre-terminated assembly instead — the labor math favors it.
Can a fan-out kit be reused?
Treat it as a one-time consumable. The block’s anchor (epoxy or crimp), the housing, and the tubes all deform or bond during installation, and re-opening a used kit risks breaking the 250 µm fibers inside. If a termination point must be re-worked, cut back and install a new kit on fresh cable end.
Fan-out kit or fusion splicing — which is better?
Neither is universally better; they solve the same problem with different labor profiles. Splicing to pigtails gives the lowest, most consistent loss and is the carrier default for permanent OSP builds. A fan-out kit with field connectors needs no splicer and suits small counts, repairs, and sites without splice infrastructure. Pre-terminated assemblies beat both when the cable has not been pulled yet and the schedule is tight.
Key Takeaways
A fiber optic fan-out kit re-protects the 250 µm fibers of a loose-tube cable in 900 µm color-coded legs so they can be connectorized or spliced in the field. Buy one only for loose-tube cable — tight-buffered and breakout-style cables do not need it. Choose by fiber count, leg size, leg length, and environment, and follow the TIA-598 color order when loading tubes. For permanent OSP builds, compare the kit path against splice-and-pigtail and factory pre-terminated assemblies on total installed cost, not on hardware price.
How BWNFiber Can Help
Fan-out points fail at the details: the wrong kit for the cable construction, legs too short for the tray, or an unanchored strength member. BWNFiber looks at the whole termination chain — cable, kit or assembly, connectors, panel, and test plan — before recommending a path.
What You Get When You Work With BWNFiber
- Engineering review: Send us the cable datasheet or a photo of the cable end and we will confirm whether a fan-out kit, splice-and-pigtail, or a factory assembly fits — before you buy anything.
- Factory assemblies when field work is not the answer: pre-terminated breakout and distribution assemblies built and 100% tested to your lengths, fiber grades, and connector plan.
- Individual test reports: every assembly ships with measured insertion-loss and return-loss values, not a batch certificate.
- Matched components: pigtails, patch cords, panels, and termination hardware specified as one system, so color codes and part numbers stay consistent across sites.
- OEM/ODM support: custom part numbering, labeling, packaging, and documentation for carriers, ISPs, and system integrators.
- Samples and spec sheets first: sample kits with datasheets and installation sheets are available so you can verify fit on your actual cable before a volume order.
- Export-ready documentation: individual test reports, RoHS/REACH declarations, and tender documentation packs for international projects and framework bids.
