The STN6800-OA1 is a series of DWDM C-Band Amplification Card based on Erbium Doped Fiber Amplifier (EDFA) including Booster Amplifiers (BA), Line Amplifiers (LA), and Pre-Amplifiers (PA). It typically operates in the C-band range (1529~1561nm) and can discuss specific working wavelength ranges with Sino-Telecom. The amplification card can be operated under constant gain (Automatic Gain Control, AGC) or constant output power (Automatic Power Control, APC). Because adopting optimal design of optical path, it can amplify the C-band signals with or without Middle Stage Access (MSA) at fixed gain or variable gain, which brings great flexibility for network applications. Both input and output ports are equipped with isolators. The integrated Variable Optical Attenuator (VOA) can be automatically adjusted to achieve smooth gain spectrum. Optical Supervisory Channel (OSC) is an optional function integrated in the module, it can be dropped or added.
