Overview

T20X is a 10G OTN Transponder board, which adopts electrical-optical-electrical conversion to realize wavelength conversion and signal regeneration, and further to realize encapsulation and decapsulation from 10 channels of 10G services to OTU2.

STN6800-T20X is suitable for STN6800 2U, 5U, 10U chassis.

Features

● The client-side port supports access of 16 channels of services at the rate below 2.5G. The typical services include STM- 1/4/16 and FE/GE.
● The client-side port supports access to 10 channels of 10G services. The typical services include STM-64, 10GE and OTU2.
● The line-side port supports 10 channels of OTU2 signals, with support for standard FEC and enhanced FEC error correction function.
● The board supports cross-connection of OTN services and overhead processing functions.
● The board supports GCC in-band management channel.
● The board supports OTN electrical-layer protection functions.

Specifications

Item	Description
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.
