PGE 608 21
EDFA Gain Block
for DWDM Applications
Description
The PGE 608 21 C-band EDFA family are 40-channel optical amplifiers
intended to be used as pre-, line- or booster amplifiers in DWDM networks.
It is designed for 1 to 3 pump laser configurations and is based on a dualsourced platform.The gain block has input and output power monitoring. The
input and output ports have isolators to attenuate spurious reflections in the
system.
External electronic circutry is needed for biasing the pump laser and for
controlling the pump laser temperature. Heat sink is provided via the bottom
surface.
