OSN1800V TNF8SL64D 2-channel STM-64 service processing board, realizes the reception and transmission of 2-channel STM-64 optical signals, completes the photoelectric conversion of STM-64 signals, extracts and inserts overhead bytes for processing, and reports alarms generated on the line. The single board consists of photoelectric conversion module, overhead processing unit, logic control unit and clock unit.TFN8SL64D single board needs to occupy 1 slot. The single board supports gray optical interfaces: I-64.1, S-64.2b, P1L1-2D2, color optical interfaces: DWDM (STM-64, 40km), and supports the processing of segment overhead of STM-64 signals. Provide abundant alarms and performance events for easy equipment management and maintenance. Support 2-channel SDH line clock. Support SNCTP protection. Supports two-fiber bidirectional multiplexing segment ring protection. Supports linear multiplexing segment protection. Supports SNCP protection. Supports online loading function of FPGA.TNF8SL64D supports hot-plugging.
