Quidway® NetEngine 80E Core Router

OC-3c/STM-1 POS Optical Interface Boards

Overview

The Quidway®NetEngine 80E core router (“NE80E” hereinafter) provides high-density

OC-3c/STM-1 POS optical interface boards to connect with the SDH transmission equipment or

other equipment. The boards provide 155M transmission channels. Currently, they are widely

applied in the networking of carriers, industries and large- and medium-sized enterprises.

CR52-8xPOS/STM1-SFP

The OC-3c/STM-1 POS optical interface boards implement POS frame encapsulation/

decapsulation of data flows and SDH/SONET mapping/demapping of POS frames, provide external

optical interfaces at a rate of 155 Mbps, and provide such functions as loopback, environment

monitoring and information query.

Hot pluggable SFP optical modules are adopted for these boards and the rate can reach 155 Mbps.

Optical modules supporting different transmission distances may be selected depending on the

networking requirements.

Specifications

The NE80E provides two types of OC-3c/STM-1 POS optical interface boards:
