Huawei 210305326210B9000065-Y-SSN1CQ101S11 SSN1CQ1 Telecom System Card / Module

The Huawei SSN1CQ1 is a 4-port channelized STM-1 CES (Circuit Emulation Service) optical interface board used in the Huawei OptiX OSN transmission platform family, deployed across SDH/MSTP transport networks carrying mixed TDM and packet traffic. The CQ1 board receives and transmits four channels of channelized STM-1 optical signals and works together with a PEG8 service-processing board to process CES service signals, allowing legacy TDM circuits to be carried transparently as circuit-emulated traffic across a packet-aware SDH network. It is primarily used to transmit and receive channelized STM-1 services on a packet ring and to manage the associated bandwidth allocation. The optical interface on this board is Class 1 laser-safe, with a maximum launched optical power under 10dBm (10mW), keeping it within standard safe-handling limits for field engineers. This unit carries material code 210305326210B9000065-Y and the board designation SSN1CQ101S11, consistent with the CQ1 family used across multiple OptiX OSN chassis variants.
