EDFA Gain Block

for DWDM Applications

Applications

• Booster amplifier in single-channel or
DWDM networks

Description

The DWDM gain block is intended to be used as a booster amplifier in WDM/
DWDM networks. 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.
