This document specifies the requirements of a DWDM C-band amplifier. The amplifier modules can be operated at constant gain (Automatic Gain Control AGC), constant output power (Automatic Power Control, APC). There are isolators at input and output port. Integrated VOA can be automatically adjusted to achieve smooth gain spectrum for different gain value. It can amplify the C-Band signal with or w/o middle stage access (MSA), which brings great flexibility for the network application. Optical supervisory channel (OSC) is optional function integrated in the module.
