OA is a family of a DWDM C-band optical amplifier card based on erbium-doped optical fibers (EDFA) including Booster Amplifiers, Line Amplifiers and Pre-Amplifiers. Its working wavelength is normally C-Band (1529~1561nm), special working wavelength range can be discussed with Sino-Telecom.The amplifier card can be operated at constant gain (Automatic Gain Control AGC), constant output power (Automatic Power Control, APC). Because of adopting optimal design of optical path, it can amplify the C-Band signal with or w/o middle stage access (MSA), at fixed gain or variable gain, which brings great flexibility for the network application. There are isolators at input and output port. Integrated VOA can be automatically adjusted to achieve smooth gain spectrum. Optical supervisory channel (OSC) is optional function integrated in the module, it can be dropped or added.

●         Support 96CH DWDM C-band System

●         Integrated Booster Amplifier and Pre-Amplifier module inside

●         Operating wavelength: 1529~1561nm (Extended band is available)

●         Multi-working mode: AGC (default), APC,ACC

●         Excellent gain flatness and NF

●         Embedded OSC channel, for remote management and topology management

●         Optional gain variability, external SFP VOA for adjusting line power

●         Monitor port for power monitoring

●         Support APR function
