About CWDM4 MSA

Specifications

The CWDM4 MSA targets a common specification for low cost 100G optical interfaces that run up to 2 km in data center applications. The MSA uses CWDM (Coarse Wavelength Division Multiplexing) technology with 4 lanes of 25 Gb/s optically multiplexed onto and demultiplexed from duplex single mode (SMF) fiber.
