Quidway® NetEngine 80 Core Router

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

Overview

The OC-3c/STM-1 POS optical interface board of the Quidway®NetEngine 80 core router

(abbreviated to NE80) consists of the PIC OC-3c/STM-1 POS optical interface and the Line

Processing Unit (LPU).

The LPU implements processing and encapsulation of link layer protocols, data flow classification

and packet filtering, data forwarding and control packet processing. The OC-3c/STM-1 POS optical

interface mainly implements POS frame encapsulation/decapsulation of data flows and

SDH/SONET mapping/demapping of POS frames, provides 155M external optical interfaces, and

enables such functions as loopback and environment monitoring.

CR-P4CF

The OC-3c/STM-1 POS optical interface board uses hot-pluggable SFP optical modules and

reaches a rate up to 155 Mbps. You can choose optical modules with different transmission

distances according to networking requirements.

Specifications

The NE80 provides two types of OC-3c/STM-1 POS optical interface boards: CR-P4CF and

CR-P8CF.
