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. Functions and features Description Basic skills Receive and send 1 STM-16 optical signal. Optical interface specifications Supports L-16.2, L-16.2Je, V-16.2Je (plus BA), U-16.2Je (plus BA and PA) optical interfaces, of which the characteristics of the L-16.2 optical interface comply with ITU-T G.957 and ITU- T G.692 is recommended. The optical interfaces of L-16.2Je, V-16.2Je (plus BA) and U-16.2Je (plus BA and PA) are Huawei’s custom standards. U-16.2Je is compatible with U-16.2. Supports standard wavelength output that complies with ITU-T G.692 recommendations. The U-16.2Je optical interface can directly access DWDM (Dense Wavelength Division Multiplexing) equipment. N3SL16 supports DWDM color optical interface, and the optical interface adopts LC connector. DWDM optical interface supports 170km and 640km transmission distance. Optical module specifications Supports optical module information detection and query. The optical interface provides laser on and off settings and automatic laser shutdown. Service Supports VC-12 / VC-3 / VC-4 services and VC-4-4c, VC-4-8c, and VC-4-16c cascade services. N2SL16 supports AU-3 service processing. Supports segment overhead processing for STM-16 signals. Supports channel overhead processing (transparent transmission and termination). Supports setting and querying J0 / J1 / C2 bytes. Overhead processing Support 1 ECC communication. Alerts and performance Provides a wealth of alarms and performance events to facilitate equipment management and maintenance.
