Lightwaves2020's MSA compliant gain block is designed for single-channel or banded channel amplification. It is a direct, low-cost drop-in replacement of existing high cost EDFAs.

The EDFA gain block includes a 980 nm pump laser, input monitor and input isolator, output monitor and output isolator, and a reel of optimized erbium-doped fiber. These components are contained within a compact 70 x 90 x 12 mm package.

A user-friendly MSA compatible 20-pin interface is included to enable the device to communicate with control electronics. The MSA EDFA is Telcordia compliant.
