The BWN-PLC-CT-2.0 is a 2×4 PLC splitter cassette with SC/APC connectors: two inputs, four outputs, 7.6dB maximum insertion loss across 1260–1650nm. The plug-in cassette drops into ODF and fiber distribution box slots, giving FTTH distribution points and small MDUs a dual-input PON split without splicing.

The BWN-PLC-CT-2.0 is a 2×4 cassette-type PLC (planar lightwave circuit) splitter with SC/APC connectors. It accepts two input fibers and distributes the optical signal evenly across four output ports over the full 1260–1650nm wavelength range, with 7.6dB maximum insertion loss. It is built for FTTH and PON distribution points that need to serve four subscribers from one or two feeder fibers without active electronics.
Specify this configuration for dual-input redundancy or two PON services on one distribution point, in enclosures with cassette slots rather than splice-only space. The module measures 100×80×10mm, terminates in SC/APC adapters, and ships with 2.0mm pigtails at 1m standard length. Single-feeder jobs fit a 1×4 cassette; SC/UPC plants and LGX chassis have sibling models compared below. For the full family, see the PLC splitter category and the cassette PLC splitter category.

For adjacent split ratios in the same 2×N family: 2×2 is ≤4dB, 2×8 is ≤11dB, 2×16 is ≤14.4dB and 2×32 is ≤17.5dB insertion loss. See the splitter loss chart (1×2 to 1×64) for the full table.
This build terminates in SC/APC connectors (green housing, 8° angled polish); SC, LC or ST in APC or UPC can be ordered. Fiber is G657A bend-insensitive or customer specified. The 2.0mm pigtail balances mechanical protection against routing space in distribution boxes; 0.9mm and 3.0mm are available.
The cassette plugs into the cassette slot of an ODF frame or fiber distribution box and presents its ports on an SC adapter plate — no splicing to install or replace. For an existing chassis, confirm the slot accepts a 100×80×10mm module. Mate APC ports only with APC cords; mating APC to UPC/PC damages the endface and adds loss.

1×4 or 2×4? One feeder at the distribution point → 1×4 cassette. Choose 2×4 when you need a second input for redundancy or a second service — the penalty is only 0.5dB (7.6dB vs 7.1dB P grade).
Cassette, blockless or LGX? Cassettes plug into ODF/FDB slots and present adapters up front — fastest to install and replace. Blockless steel-tube splitters are spliced inside closures. LGX modules fit standard rack-mount LGX chassis. Match the package to the enclosure.
APC or UPC? PON, FTTH and CATV plants standardize on APC for its higher return loss (≥55dB here). If your plant is UPC throughout, use the SC/UPC sibling below rather than mixing polishes on one link.
Budget check. In a Class B+ GPON budget of about 28dB, a 2×4 split takes ≤7.6dB, wavelength/temperature variation adds ≤0.8dB, and connector pairs take 2–3dB — leaving roughly 17dB for fiber and splices, enough for several kilometers. Verify your OLT/ONU classes against the splitter loss chart before finalizing.
| Model | Package | Polish | Choose when |
|---|---|---|---|
| BWN-PLC-CT-2.0-2X4-SC-APC (this page) | Cassette, 100×80×10mm | SC/APC | ODF/FDB cassette slots on a PON/FTTH plant |
| BWN-PLC-IM-2X4-SC-UPC insertion module | Insertion ABS module | SC/UPC | UPC-standardized plants, box/tray mounting |
| BWN-PLC-IM-2X4-SC-APC LGX | LGX module | SC/APC | Standard LGX rack chassis in central offices or racks |
All three share the same 2×4 optical core (≤7.6dB IL, ≥55dB RL on APC builds) — the choice is mechanical and polish, not performance. For splice-in steel-tube formats see the blockless mini PLC splitter category; for concept background see the fiber optic splitter overview.
Optical performance is verified against the parameters in the specification table — insertion loss, uniformity, return loss, PDL, directivity and wavelength dependent loss. Compliance with Telcordia GR-1209-CORE and GR-1221-CORE is stated per BWNFiber product documentation.
Standard configuration: 2×4 cassette, SC/APC, G657A fiber, 2.0mm pigtails, 1m length. Pigtail diameter and length, connector type and polish are customizable per the specification table. Confirm scheduling with the sales team at inquiry.

A 2×4 PLC splitter takes two input fibers and splits the signal evenly to four outputs. It serves FTTH distribution points and small MDUs where a second input gives feeder redundancy or a second PON service — without two separate 1×4 splitters. Dual input costs only 0.5dB more than a 1×4 (7.6dB vs 7.1dB).
Maximum insertion loss is ≤7.6dB across 1260–1650nm, with ≤1.0dB port-to-port uniformity, per the BWNFiber 2×N specification table. Add connector pair losses and fiber attenuation on top when building a link budget; the splitter loss chart lists every ratio from 1×2 to 1×64.
Match the package to the enclosure. Cassettes plug into ODF and distribution box slots with front adapters — no splicing to install or replace. Blockless steel-tube splitters splice into closures. LGX modules fit rack-mount LGX chassis. The optical core is the same; only the mechanics differ.
PON, FTTH and CATV plants normally specify APC: the 8° angled endface delivers ≥55dB return loss here and keeps reflectance away from OLT lasers and 1550nm video paths. Choose UPC only where the existing plant is UPC throughout — then use the SC/UPC 2×4 insertion-module sibling instead of mixing polishes.
Yes. The cassette platform supports SC, LC and ST connectors in APC or UPC polish, 0.9mm, 2.0mm or 3.0mm pigtail diameters, and pigtail lengths beyond the standard 1m. State connector, polish, diameter and length in the inquiry.
Test all eight paths (2 inputs × 4 outputs) with an OLTS at 1310, 1490 and 1550nm. Each path should read ≤7.6dB plus your connector allowance, and the four outputs from one input should sit within the ≤1.0dB uniformity window. A single port reading well above the limit usually means a contaminated connector — clean and retest before rejecting the unit.
The splitter is rated for -40～+85°C operating and storage, with ≤0.4dB temperature stability across that range, so it suits unconditioned outdoor cabinets. The cassette is not a sealed closure — install it inside an ODF, distribution box or cabinet that provides the enclosure.
