OA (BA+PA): EDFA Card for STN6800-D16HE

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).

Overview

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.
