OA (Optical Amplifier) used for DCI BOX
OA (Optical Amplifier) The main function of the optical amplifier board is to compensate the power of the signal light in the transmission link, which can simultaneously amplify the optical signal of up to 48 channels (channel interval of 100GHz) or 96 channels (channel interval of 50GHz) in the C-band. It has the characteristics of flat gain, adjustable gain, low noise index, etc. At the same time, the built-in OSC optical monitoring channel of the board supports OSC-based DCN communication, which is an indispensable part of DWDM system and future high-speed system and all-optical network long-distance transmission.
