Quidway® NetEngine 80E Core Router
OC-12c/STM-4c POS Optical Interface Board
Overview
The Quidway®NetEngine 80E core router (“NE80E” hereinafter) provides high-density
OC-12c/STM-4c POS optical interface boards to connect with the SDH transmission equipment or
other equipment. The boards may be plugged in any service slots of the NE80E and provide 622M
transmission channels.
CR52-4xPOS/STM4-SFP
The OC-12c/STM-4c 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 622 Mbps, and provide such functions as loopback, environment
monitoring and information query.
They support hot plugging. The user may add or remove them as needed while the equipment is
powered on without affecting the services of the other interface boards. In addition, hot pluggable
SFP optical modules are adopted for plug and play. The rate can reach 622 Mbps. Optical modules
supporting different transmission distances may be selected depending on the networking
requirements.
Specifications
Currently, the NE80E provides one type of OC-12c/STM-4c POS optical interface board:
CR52-4xPOS/STM4-SFP.
