Erbium-Doped Fiber Amplifier
for Digital Applications
PGE 608 03
Description
The PGE 608 03 is an integrated, output power-locked amplifier. It has
optically isolated input and output ports as well as input and output power
monitoring. The serial and parallel interface is provided through a DB-25
electrical connector. The modules are based on industry standard platforms
and are optimized for single channel SDH/SONET applications.
