STN6800-T20X

STN6800-T20X is high density 10G OTN transponder (20 ports 10G) card. It adopts electrical-optical-electrical conversion to realize wavelength conversion and signal regeneration to realize encapsulation and decapsulation from 10 channels of 10G services to OTU2. STN6800-T20X is suitable for STN6800 2U, 5U, 10U chassis.

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 detailed functions of STN6800-T20X:

 The client-side port supports access of 10 channels of 10G services. The typical services include STM-64, 10GE and OTU2.

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.
