Huawei SSN3SL16A Board Product Overview Huawei SSN3SL16A Board is an optical interface board, which can be used on the OptiX OSN7 500 / OSN3500 / OSN2500 / OSN1500 series equipment to realize the reception and transmission of one STM-16 optical signal. Through this board, Huawei SL16A sends the received optical signals to the cross-side after 0 / E conversion, and at the same time, the cross-side electrical signals are sent after E / O conversion. The SDH line board can form a ring network or a chain network with the SLD16 and SLQ16 optical boards in the system. The Huawei SL16A board consists of a photoelectric conversion module, a MUX / DEMUX module, an SDH overhead processing module, a logic control module, and a power module. Huawei SSN3SL16A Board Product Feature Supports optical loop-level inner loopback and outer loopback functions. Supports VC-4 channel inner loopback function, SSN3SL16A supports VC-4 channel inner loopback function and outer loopback function. Supports soft reset and hard reset.
