EDFA-OA is an OTM terminal optical amplification card for the STN6800-D16 platform from Sino-Telecom, which integrates a power amplifier and a preamplifier and supports bidirectional amplification. The EDFA-OA card supports C-band transmission with a transmission distance of 0~120km, and integrates optical signal wavelength and power monitoring, fiber link attenuation and break point testing, 1510nm network management monitoring channel, and intra-station and inter-station adaptive gain equalization (APR).
The power amplifier is a fixed gain amplifier, while the preamplifier is an adjustable gain amplifier.
Complete C-band signal power amplification function, and support gain adjustable function;
The laser can be turned on and off through network management settings, facilitating testing and operation and maintenance;
The board card is equipped with a VOA module, which can be used to automatically adjust the input optical power of the EDFA module.
Complete the receiving, transmitting, controlling, and processing of optical supervisory channel signals;
Realize the multiplexing and demultiplexing of the main optical channel and the optical supervisory channel;
In conjunction with the OTDR board card, it completes the online OTDR detection function, enabling the detection of the fiber status in the optical line system;
Provide an online monitoring port capable of outputting a small amount of optical signal to monitor the spectral performance of the optical signal without interrupting the service;
Support the detection and reporting of optical power;
Support the reporting of single board card alarms and performance events.
