The GB-FMSA011-CB/CP series are compact optical amplifier Gain Blocks in the MSA size, which offers maximum output up to 20 dBm at the C-band. The Gain Blocks can be used for many applications including single channel amplification, DWDM subsystems, optical cross-connect, optical add-drop, channel equalization and pre-emphasis.

Features

● Small package size: 70 x 90 x 12 mm
(Size and shape are MSA gain block compatible)
● C-band up to +20dBm of optical output
● Incorporating control electronics
● ALC / APC mode (ALC: Automatic output signal power control, APC: Automatic pumping power control)
● RS232 command interface with monitoring and control function (Optional)
● Evaluation board available upon request (Optional)

Applications

● Single-channel
● DWDM sub-systems
● Optical cross-connects
● Optical add/drop multiplex
● Channel equalization and pre-emphasis
