FAQs

Q: Does CWDM4 require FEC?
A: Yes. RS-FEC on the host is required by the CWDM4 MSA to achieve the specified BER.

Q: What wavelengths does CWDM4 use?
A: It uses four CWDM lanes centered at 1271, 1291, 1311, and 1331 nm.

Q: What fiber and connector are needed?
A: Use OS2 single-mode fiber with duplex LC connectors for up to 2 km reach.

Q: Is this a good alternative to PSM4?
A: Yes, CWDM4 provides 2 km reach over duplex LC SMF and simplifies cabling compared to MPO-based PSM4.
