M2X16 Functional Unit Description

Item

Description

Client-side Optical Module

M2X16 board provides 16 client-side optical transceiver modules, each of which is pluggable packaing module (SFP).

Receiving Direction: access STM-1/4/16 (OC-3/12/48)and FE/GE services to achieve optical-electrical conversion function of service signals.

Transmitting Direction: Achieve electrical-optical conversion and output STM-1/4/16 (OC-3/12/48) and FE/GE service signals.

ODUk Mapping Unit

Realize the mapping/demapping process of client service electrical signals and ODUk (k=0, 1) signals, and detect and process ODUk overhead.

Service Cross-connect Unit

Realize the cross-connect function of client service signals.

OTU Framing Unit

Detect and process the overhead of OTU2 frame, and complete the multiplexing/demultiplexing process of ODUk (k=0, 1) and OTU2 signals. Moreover, realize FEC coding and error correction functions.

Line-Side Optical Module

M2X16 board provides 2 line-side optical transceiver modules which are with pluggable packaging (XFP), so as to realize the 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 OUT framing unit.
