Client-side Optical Module |
T20X board provides 10 client-side optical transceiver modules, each of which is pluggable packaing module (SFP+). Receiving Direction: Access client services such as STM-64 (OC-192), 10GE and OTU2, and achieve optical-electrical conversion function of service signals. Transmitting Direction: Achieve electrical-optical conversion and output client service signals such as STM-64 (OC-192), 10GE and OTU2. |
|
ODUk Mapping Unit |
Realize the mapping/demapping process of client service electrical signals and ODUk (k=2) signals, and detect and process ODUk overhead. |
|
Service Cross-connect Unit |
Realize the cross-connect function of client service signals of the board, or the client service signals of other boards which are transmitted through the backplane bus. |
|
OTU Framing Unit |
Detect and process the overhead of OTU2 frame, and complete the multiplexing/demultiplexing process of ODUk (k=0, 1, 2) and OTU2 signals. Moreover, realize FEC coding and error correction functions. |
|
Line-side Optical Module |
T20X board provides 10 line-side optical transceiver moduels, which are with pluggable packaging (SFP+), so as to realize optical-electrical conversion and electrical-optical conversion of OTU2 signals. Transmitting Direction: Access OTU2 electrical signals from OTU framing unit, realize electrical-optical conversion and output OTU2 optical signals. Receiving Direction: Realize optical-electrical conversion of OTU2 optical signals and output them to OTU framing unit. |
