Description
Huawei SSN1BPA Board is Optical Booster & Pre-amplifier Board (-38dBm~-10dBm,22dB;-6dBm~+3dBm,17dBm, LC)
Huawei SSN1BPA Board Product Overview
Huawei SSN1BPA Board consists of 1 power amplifier and 1 preamplifier board. When the optical signal is transmitted over a long distance, the signal attenuation is more. In order for the optical receiver to receive the normal optical signal, it is necessary to add an optical power amplifier board (BA) and a pre-amplifier board (PA).
Huawei N1BPA consists of 2 EDFA optical modules, and N2BPA consists of 1 EDFA optical module, which is used to generate optical amplification effects. The BPA board is an optical power amplifier and preamplifier board. It provides 1 channel power amplifier (BA) and 1 channel preamplifier (PA), which are respectively applied to the sending end and receiving end of OptiX OSN equipment.

Huawei SSN1BPA Board Product Features
- Basic Function
Increase the transmission optical power of the circuit board to + 13dBm ~ + 15dBm or + 15dBm ~ + 17dBm, so that the transmission distance can reach 120km or 130km or more (G.652 fiber, loss is calculated as 0.275dB / km). - Pre-amplification function
Provide PA module to complete the pre-amplification of the received optical signal, which can make the small signal power gain 22dB ~ 25dB (N1BPA), 22dB ~ 33dB (N2BPA). - Support EDFA
Support EDFA (Erbium-Doped Fiber Amplifier) module laser temperature automatic control and optical power automatic control.
Support EDFA module input and output optical power automatic monitoring and optical power query.
Support the protection function of EDFA module. When there is no input light, the laser is automatically turned off. When the input light is restored, the laser is automatically turned on.
Performance monitoring and alarm monitoring
Support the reporting of laser performance parameters. Provide abundant alarms and performance events to facilitate equipment management and maintenance. - software upgrade
Support the smooth upgrade and expansion of software.
