An MPO 12 fiber OM5 to LC duplex breakout cable connects one MPO-12 interface to six LC duplex legs. The supplied configuration uses a PC female MPO connector, LC/UPC duplex connectors and lime-green OM5 multimode fiber. Specify the complete fiber map and branch layout before ordering.
Product Overview
Use this assembly where an approved cabling design distributes twelve OM5 fiber paths from an MPO connection to six duplex termination points. Each duplex leg carries two fibers; the six connectors do not establish six supported network links without compatible equipment and correct transmit-to-receive routing.
The configuration is intended for full twelve-fiber distribution. It is not automatically interchangeable with a four-leg SR4 harness. A connector that fits mechanically can still have the wrong populated positions, pairing or polarity. Submit both endpoint part numbers and the intervening cassette or trunk map for review.
Compare other configurations on the MPO breakout and harness selection page. This page covers the supplied OM5 six-duplex assembly; it does not establish availability of every product in the family.
Key Features
- One MPO-12/PC female interface to six LC/UPC duplex legs, as described in the source.
- Twelve OM5 50/125 μm multimode fibers with a lime-green jacket.
- A full fiber-position map to be approved alongside LC leg labels and destinations.
- Factory-selected polarity; the source does not specify field-switchable polarity.
- Metric length and fanout dimensions recorded separately for quotation.
- One configuration schedule for polarity, jacket and length choices, avoiding repetitive product-name rows.

Selection Guidance
Confirm twelve paths and six destinations
Prepare a schedule for legs L1–L6. For each leg, record both MPO fiber positions, both LC fiber identifiers, the destination port and the intended transmit/receive direction. Do not assume adjacent MPO positions form each duplex pair. Request an end-view drawing showing viewing direction, key orientation and pinning.
| Leg | MPO positions for the two fibers | LC identifiers / destination | Acceptance record |
|---|---|---|---|
| L1 | Buyer and engineering to approve | Record both fibers and port | Continuity and agreed optical results |
| L2 | Buyer and engineering to approve | Record both fibers and port | Continuity and agreed optical results |
| L3 | Buyer and engineering to approve | Record both fibers and port | Continuity and agreed optical results |
| L4 | Buyer and engineering to approve | Record both fibers and port | Continuity and agreed optical results |
| L5 | Buyer and engineering to approve | Record both fibers and port | Continuity and agreed optical results |
| L6 | Buyer and engineering to approve | Record both fibers and port | Continuity and agreed optical results |
Separate distribution from transceiver breakout
| Required connection | Selection decision |
|---|---|
| Twelve-fiber OM5 distribution to six duplex destinations | Review this configuration against the complete path map |
| Four-lane SR4 breakout | Request the equipment-specific four-leg map; do not order this six-leg assembly as an automatic substitute |
| Duplex SWDM optical link | Confirm the actual optics, supported fiber and channel budget; jacket color does not establish compatibility |
| OS2 single-mode connection | Select a separately specified single-mode assembly |
Cisco’s QSFP documentation gives module-specific interface, reach and loss-budget requirements. It is a reminder to qualify the optics and channel together, not evidence that this BWNFiber assembly is approved for a Cisco module.
Define branch geometry before overall length
Measure from the agreed MPO reference point to each LC connector reference point. Identify the fanout transition separately. State whether the legs are equal or staggered, how far each destination is from the transition and where service slack is required. Avoid defining every leg only by a single overall length when the ports are staggered.
The source lists 30 cm as the default fanout, but a default is not an installation drawing. The routing must respect the approved cable bend radius and connector strain relief. Dimensions, tolerances and any staggered construction are confirmation with BWNFiber.
Agree polarity and optical acceptance
Select the factory polarity only after checking the complete channel. Type A/B/C labels are insufficient without the actual fiber map and mating interfaces. Use the channel polarity design guide for the wider design process.
Documents to request before order release
Request the approved drawing, fiber and jacket identification, and the proposed inspection and test record. Specify per-fiber continuity, end-face inspection scope, maximum insertion loss and minimum return loss where applicable, test wavelength and reference method. IEC 61300-3-4 is listed as a method reference in the source; exact method applicability and performed tests are confirmation with BWNFiber. A typical connector loss is not an assembly acceptance limit, and factory results do not replace the installed channel budget.
Applications
| Selection scenario | Required condition |
|---|---|
| OM5 MPO distribution to an LC patch area | Six duplex destinations and all twelve paths match the approved map |
| Cassette-related patching | Actual MPO-side connector, cassette internal map and LC destination assignment are known |
| Existing WBMMF cabling plant | Fiber grade, optics and channel requirements are verified from the system documents |
| Repeat project supply | The same approved drawing revision and acceptance schedule are referenced |
These are design scenarios, not customer case studies. For enclosure-based distribution, review the breakout versus cassette comparison.

The source contains 117 option rows: three polarity requests × three jacket requests × thirteen lengths. They are retained in the accompanying order-options CSV, not represented as stock or as 117 separately approved products. Metric values govern; 1 m is approximately 3.28 ft and 1.5 m is approximately 4.92 ft.
Custom lengths, 0.9 mm legs, staggered fanout, pulling eyes, OEM print, labels and packaging are source-listed requests. Feasibility, MOQ, lead time and the final part-number format are confirmation with BWNFiber. Do not treat the source’s suggested order-code pattern as an issued SKU.
Why Source from BWNFiber
Send BWNFiber one configuration record covering the six destinations, connector identity, lengths and acceptance requirements. Ask for the proposed build and any exceptions to be identified in the quotation. This creates a reference that procurement, installation and receiving teams can use for the same assembly.
The source mentions factory termination, inspection and IL/RL records. Actual test coverage, record availability, traceability and production capability for this item are confirmation with BWNFiber. Request evidence for the quoted build before approving a sample or repeat order.
Need a Configuration Review or Sample?
Request a quote for the six-duplex OM5 configuration with the endpoint models, completed leg map, overall length, fanout dimensions, jacket and quantity. Ask BWNFiber to identify open specifications and available documents before order approval.
