The MMC portfolio also lists SC, MPO-12, MPO-16 and MPO-24 breakout options, plus 12F and 24F MMC-side configurations. These builds require confirmation of connector quantities, active fibers and channel mapping before quotation.
Choosing the Breakout Interface
- LC Duplex: use for equipment whose optical modules present duplex LC interfaces.
- SC: use only where the equipment or existing distribution interface requires SC.
- MPO-12, MPO-16 or MPO-24: use for migration or interconnection with the matching MPO interface and verified polarity.
Do not select the breakout solely from a transceiver’s package name, such as QSFP-DD or OSFP. Confirm the actual optical receptacle, lane count and reach in the transceiver datasheet.
Equal vs. Staggered Legs
Equal legs simplify assemblies where destination ports are aligned. Staggered legs match different port positions and reduce excess slack in dense racks. Provide the rack elevation or the required leg-by-leg dimensions so the harness can be built and labeled correctly.
