MPO 12 Fiber OS2 Patch Cord
A 12-fiber OS2 MPO jumper for single-mode cassette and panel patching, built to a fixed polarity.

Product Overview
This 12-fiber OS2 MPO patch cord links cassettes, adapter panels and equipment ports inside high-density racks. Both ends use generic MPO APC female connectors on a yellow 3.0 mm jacket. Polarity is built as Type A, B or C at the factory and is not field-switchable.
Key Features
- Generic MPO connectors on both ends, not US Conec MTP and not SENKO MPO
- 12 fibers, OS2 9/125 μm single-mode, yellow jacket
- APC female (unpinned) default gender
- Factory-set polarity Method A, B or C; not field-switchable
- Factory terminated and inspected before shipment
- Standard lengths from 0.5 m (2 ft) to 15 m (49 ft)
- Jacket options: OFNP, OFNR and LSZH
- OEM labeling, serial numbers and test records available
Applications
Use this 12-fiber OS2 APC assembly for single-mode cassette and panel patching. An MPO-12 ferrule can also carry only 8 active fibers; this page is the full 12-fiber build. Selected PSM4 / DR4 links should use the 8-fiber OS2 page unless the module map is confirmed as 12-fiber.
Typical uses:
- In-cabinet OS2 patching in MDA, HDA and EDA zones
- Cassette-to-cassette and adapter-panel single-mode interconnect
- 12-fiber structured single-mode channels through cassettes
- High-density OS2 interconnect between adjacent racks

- Project configuration by jacket, length, labeling and packaging
- Build-sheet review before production on OEM and project orders
- Serialized IL / RL and polarity records available with the shipment
- One factory path for catalog SKUs and private-label assemblies

Frequently Asked Questions
Which options do I select on this page?
Select polarity Type A, B or C, jacket LSZH / OFNP / OFNR, and length from 0.5 m (2 ft) to 15 m (49 ft). Connector family, fiber count, fiber type, polish and gender stay fixed on this page.
How is this different from a US Conec MTP or SENKO MPO jumper?
This page uses generic MPO connectors. Use MTP, MTP PRO or SENKO names only on pages that install those brands.
What is included when I source this jumper from BWNFiber?
Each assembly is factory terminated and inspected. Project orders can include polarity notes, custom length, cable print, labeled packaging and IL / RL records.
Can I change polarity or pin gender after installation?
No. This is a standard generic MPO assembly. Polarity and gender are fixed when the cord is built. Order the correct Type A, B or C method before production.
Should I use this 12-fiber OS2 jumper for 400G DR4?
Only if the module map is confirmed. Many DR4 ports use 8 active fibers in an MPO-12 interface. This page is the full 12-fiber build. If the link uses 8 live fibers, order the 8-fiber OS2 MPO patch cord or state 8 active fibers in the order notes.
