Client-side Optical Module

H1L10 board provides 10 client-side optical transceiver modules, each of which is pluggable packaging module (SFP+).

Receiving Direction: Access client services such as STM-64 (OC-192) and 10GE to realize optical-electrical conversion function of service signals.

Transmitting Direction: Realize electrical-optical conversion and output client service signals such as STM-64 (OC-192) and 10GE.

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 OTU4 frame, and complete the multiplexing/demultiplexing process of ODUk (k=2) and OTU4 signals.

Line-Side Optical Module

H1L10 board provides 1 line-side optical transceiver module, which is pluggable packaing module (CFP), so as to realize optical-electrical conversion and electrical-optical conversion of OTU4 signals.

Transmitting Direction: Access OTU4 electrical signals from OTU framing unit, and realize PM-QPSK modulation and FEC coding of signals, and then achieve electrical-optical conversion. After that, OTU4 optical signals are output.

Receiving Direction: Realize optical-electrical conversion of OTU4 optical signals. Then achieve DSP processing and FEC error correction. After that, the signals are output to OTU framing unit.
