C+ +Band EDFA
Product Introduction
This document specifies the requirements of a DWDM C-band amplifier. The amplifier modules include one gain unit which can be operated at constant gain (Automatic Gain Control AGC) or constant output power (Automatic Power Control, APC). There are isolators at input and output port. Integrated VOA can be closed control for accurate attenuation, in order to achieve smooth gain spectrum for different target gain.
