FAQs

Q: Will this interoperate with CWDM4 or LR4?
A: No. PSM4 is a parallel single-mode interface and must link to another PSM4 module.

Q: What connector and fiber are needed?
A: Single-mode fiber with MPO‑12 (MTP) connectors; ensure proper polarity and cleanliness.

Q: Is FEC required?
A: Typically not for 500 m links, but enabling host FEC can provide additional margin.

Q: How many fibers are active?
A: Eight fibers (4 transmit, 4 receive) within the MPO‑12 interface.
