This semiconductor based variable optical gain array is intended for use in high bit rate applications (2.5
Gbit/s, 10 Gbit/s and 40 Gbit/s) to provide controllable gain to an array of 8 optical channels.An array of 8
optical amplifiers, a thermistor and thermo-electric cooler are included in a butterfly style package with single
mode fiber ribbon pigtails.
