OVERVIEW
Finisar's Compact 70x90 mm Variable Gain (VG) EDFA is a micro processor-controlled module
for C-band amplification. The Compact VG module provides drop-in replacement software
and hardware compatibility to line cards already designed to accommodate fixed gain (FG)
EDFA. The VG EDFA, enables a new modular and flexible approach to amplifier design and can
be mixed and matched with FG EDFAs to support all amplifier configurations using the same
line card, including: single stage, dual-stage with mid-stage access, and East/West separation
for ROADM applications. In addition, communication between two modules on a line card
is supported, thus allowing the modules to be operated as a single unit in a master/slave
configuration.
Besides fixed gain and variable gain configurations, this flexible platform can also accommodate
a FG EDFA with VOA for cost reduction and backward compatibility. The Variable Gain Compact
amplifier provides a large dynamic gain range, excellent gain flatness and very low noise figure
over all its operational regimes. The fast automatic gain control (AGC) digital control electronics
allow the amplifier to keep the gain constant and stable particularly in cases when there are
very fast and large changes in the input power.
