For a direct 40GBASE-SR4 or 100GBASE-SR4 link, Type B is the common polarity choice. Because SR4 ports are normally pinned, the cable is usually ordered female to female. Confirm both device interfaces before release.
FB-LINK MPO 12-Core OM4 Fiber Optic Patch Cord
The FB-LINK MPO 12-Core OM4 Fiber Optic Patch Cord is a pre-terminated 12-fiber multimode jumper for 40G and 100G data center links. Choose the polarity, connector gender, jacket and length, then receive an IL/RL-tested patch cord with its own report.
- Product Introduction
Check Whether This MPO-12 OM4 Cable Fits Your Link
The MPO 12-Core OM4 Fiber Optic Patch Cord fits direct SR4 connections, pre-terminated backbone trunks and cassette-based migration links when the polarity and connector gender match every component in the channel.
Direct optics
Connect two SR4 transceiver ports
Structured cabling
Run a trunk through cassettes or panels
Type A or Type C may be required when cassettes and duplex patch cords manage the transmit and receive flip. The correct answer depends on the full channel, not the trunk viewed in isolation.
Migration path
Break one parallel port into four channels
Pair the 12-fiber trunk with the appropriate MPO-to-LC cassette or harness for 4×10G or 4×25G breakout. Keep the selected polarity method consistent from the optic to the far-end equipment.
The costly mistake is mixing polarity methods. A cable can pass an optical-loss test and still fail the live link when Tx does not land on Rx. Send the transceiver, trunk, adapter and cassette sequence to the FB-LINK MPO cabling team for a pre-order check.

Keep More Link Margin With a Low-Loss MPO-12 OM4 Assembly
The low-loss version of the MPO 12-Core OM4 Fiber Optic Patch Cord limits insertion loss to ≤0.35 dB per mated pair, compared with ≤0.70 dB for the standard-loss option. That difference matters when the channel includes several adapters, cassettes or patching points.
A lower connector allowance leaves more budget for the installed fiber and future moves, adds or changes. It does not replace a channel calculation, but it gives the designer more room before the planned receive power approaches the transceiver limit.
Each cable is measured for insertion loss and return loss before shipment. The individual report gives the installer a baseline for receiving inspection and helps the project team separate a cabling issue from contamination, an incorrect polarity path or an equipment problem.
Choose MPO Polarity and Connector Gender Without Rework
Polarity determines where fibers 1 through 12 land at the far end, while connector gender determines whether the guide pins can mate. Both choices must be checked against the entire channel before production.
Type A keeps each fiber position straight through. It is used in Method A systems where the transmit and receive flip is handled elsewhere in the channel.
Type B reverses the fiber order. It is the common choice for direct 40G and 100G SR4 connections and parallel-optics trunks.
Type C flips each adjacent pair. It is used in Method C duplex systems where the trunk performs the transmit and receive crossover.
Connector gender
One pinned connector mates with one unpinned connector
Male MPO connectors contain guide pins; female connectors do not. Most SR4 transceiver ports are pinned, so a cable connected directly to an optic is normally female. An adapter between two cable assemblies may require one cable end to be male.
Unsure? Send the part numbers or a simple channel diagram to FB-LINK for an MPO-12 polarity and gender check before the quote is finalized.
FB-LINK Builds Custom MPO Fiber Assemblies Around Your BOM
FB-LINK configures the MPO 12-Core OM4 Fiber Optic Patch Cord by length, polarity, gender, jacket, cable construction, labels and packaging. For system integrators, distributors and project buyers, this keeps the drawing, sample, production and test records in one workflow.
Connector choice
Order standard MPO or genuine US Conec MTP® ferrules with the required male or female configuration.
Pathway fit
Select ribbon, flat or 3.0 mm round cable with an LSZH, OFNP or OFNR jacket.
Installation protection
Add a pulling eye when the pre-terminated assembly must travel through conduit.
Project identification
Specify meter marks, cable labels, serial numbers, report format and packing instructions.
The same manufacturing scope also covers 8, 16, 24 and 32-fiber counts plus OM3, OM5 and OS2 when a project includes more than one cable family.
Use This OM4 MPO Trunk Across 10G, 40G and 100G Plans
The MPO 12-Core OM4 Fiber Optic Patch Cord uses 4700 MHz·km OM4 fiber for common in-row, row-to-row and equipment-to-panel routes. The same pre-terminated patch cord can serve direct parallel-optics links or cassette-based duplex migration when the channel components are selected together.
40GBASE-SR4
Connect QSFP+ ports directly
The 12-fiber OM4 assembly supports 40G SR4 links up to 150 m when gender and polarity match the two optics.
100GBASE-SR4
Build leaf and spine connections
Support 100G SR4 links up to 100 m between QSFP28 ports in high-density switching fabrics.
Structured backbone
Link cassettes and adapter panels
Build factory-terminated runs between MDA, HDA and EDA areas while reducing field termination and rack-side connector count.
Breakout migration
Create 4×10G or 4×25G channels
Use an MPO-to-LC cassette or harness when one parallel-optics port must be presented as four duplex links.
Enterprise pathways
Match riser and plenum spaces
Choose OFNR for vertical pathways or OFNP for air-handling spaces, and add a pulling eye for conduit installation.
10GBASE-SR
Reuse the trunk through a cassette
OM4 supports 10GBASE-SR up to 400 m when the trunk is presented through the correct duplex cassette architecture.
Approve the Drawing and Sample Before Bulk MPO Production
The OEM process converts your BOM into a confirmed production drawing, an optional pre-production sample and a repeatable batch record. It gives the sourcing manager clear approval points before quantity production begins.

Every FB-LINK MPO Patch Cord Ships With Traceable Test Evidence
Every MPO 12-Core OM4 Fiber Optic Patch Cord is checked for end-face geometry, insertion loss, return loss and polarity before release. An individual report travels with the patch cord, giving the receiving team results tied to that unit rather than a generic statement about the batch.
FB-LINK controls ribbon-fiber preparation, MT ferrule termination, polishing, inspection and final measurement in-house. That makes it easier to reproduce an approved 12-fiber multimode build across a repeat order and investigate any non-conforming cable.
End-face geometry
3D interferometer inspection checks the polished multi-fiber interface.
Optical performance
Per-channel IL/RL measurement confirms the ordered standard-loss or low-loss grade.
Polarity verification
Fiber mapping is checked against the selected Type A, Type B or Type C method.
Batch traceability
Dust-controlled assembly and production records support repeat orders and review.
Protect Bulk MPO Cable Orders From Test Bench to Warehouse
For bulk orders of the MPO 12-Core OM4 Fiber Optic Patch Cord, FB-LINK can align individual labels, report format, bags and carton marks with the receiving process, then ship by express or sea freight with export documentation.
Protect every connector end face
Dust caps and individual bags keep the ferrules covered through transport, receiving and installation staging. The cable-specific IL/RL report stays with the unit.
Match the warehouse identification plan
Custom labels, serial numbers and carton marks can follow the project schedule or distributor stock convention.
Choose the delivery route by schedule
DHL, FedEx and UPS air express are available alongside sea freight. Use quantity and site date to decide the appropriate method.
Plan Bulk MPO Patch Cord Orders With Clear Lead Times
Start with one sample when the configuration needs approval, then plan standard and custom production separately. Standard lengths typically ship in 1–3 working days; custom cable assemblies typically require 5–10 working days.
| Sample MOQ | 1 piece |
|---|---|
| Custom-build MOQ | Flexible; confirm against the required configuration and volume |
| Standard lengths | Typically 1–3 working days |
| Custom assemblies | Typically 5–10 working days |
| Volume pricing | Tiered pricing is available for wholesale quantities |
| Quality assurance | 12-month warranty against manufacturing defects; non-conforming cables replaced |

Use the existing product and drawing images for initial review, then replace the two marked slots with project-relevant photos that help buyers verify installation and delivery readiness.
Why System Integrators Shortlist FB-LINK for MPO Cable Projects
The practical advantage is a cable that matches the reviewed link diagram, arrives with cable-level test evidence and can be reproduced across later sites or project phases.
As a custom MPO fiber optic patch cord manufacturer and OEM supplier, FB-LINK keeps termination, polishing, inspection, optical testing, labels and packing within the same production scope. The value is practical: fewer handoffs between approval and delivery, plus a clearer record when the order is repeated.
Configuration review
Polarity, connector gender and link-loss questions can be resolved before the PO.
Measured performance
3D end-face inspection and per-channel IL/RL results support acceptance.
Component choice
Standard MPO and genuine US Conec MTP® ferrule options cover different project priorities.
Repeat-order control
Drawings, labels, reports and batch records help reproduce the approved assembly.
Questions Procurement Teams Ask Before Ordering MPO Cables
These answers cover the decisions that most often delay an MPO order: application fit, polarity, connector gender, component choice, sample quantity and production lead time.
What is the MPO 12-Core OM4 Fiber Optic Patch Cord used for?
It connects 40GBASE-SR4 and 100GBASE-SR4 transceivers, MPO cassettes and adapter panels in data center and enterprise cabling. One MPO-12 interface carries 12 fibers; the specified OM4 assembly supports 40G SR4 up to 150 m and 100G SR4 up to 100 m.
Which polarity should I order: Type A, Type B or Type C?
Type B is commonly selected for direct SR4 transceiver-to-transceiver links. Type A suits Method A structured systems, while Type C performs the pair flip for Method C duplex systems. The FB-LINK MPO application team can verify the mapping from your transceiver, trunk and cassette sequence before production.
Should the MPO connector be male or female?
Every MPO mating pair requires one pinned connector and one unpinned connector. Because SR4 transceiver ports are generally pinned, a cord plugged directly into the optic is normally female. Confirm the gender of every cassette and adapter before the order is released.
What is the difference between MPO and MTP®?
MTP® is US Conec's enhanced MPO connector design and follows the IEC 61754-7 interface, so MPO and MTP® connectors can intermate. FB-LINK supplies standard MPO for cost-led projects and genuine US Conec MTP® ferrules when the specified build calls for them.
What are the MOQ and lead times for a wholesale MPO-12 OM4 order?
The sample MOQ is one piece. Standard lengths typically ship in 1–3 working days, while custom assemblies typically require 5–10 working days. A bulk quotation is based on the quantity breakdown and final configuration.
What information is required for a custom 12-fiber OM4 patch cord?
Specify fiber count, length, polarity, connector gender, jacket rating, cable construction, labels, packaging and quantity. FB-LINK can prepare a production drawing for approval and provide a pre-production sample for most custom MPO cable configurations.
Request the Right MPO 12-Core OM4 Fiber Optic Patch Cord From FB-LINK
Send the known configuration and quantity. The FB-LINK MPO cable team can return a quotation, drawing and datasheet for technical and purchasing review; if polarity or gender is still open, include the link diagram.
