Quidway® NetEngine 40 Series Universal Switching

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

Overview

The OC-3c/STM-1 POS optical interface board of the Quidway® NetEngine 40 universal

switching router (USR) series (abbreviated as NE40) consists of the PIC OC-3c/STM-1 POS

optical interface and the line processing unit (LPU). 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, environment monitoring and information inquiry.

CR-P4CF

This board helps NE40 connect with SDH transmission equipment or others by providing

155Mbps transmission channels. It now is widely accepted by operators and large and

medium-sized enterprises.

The board is designed with the SFP optical module that supports hot swapping. Therefore, it

allows you to select optical modules according to transmission distance.

Specifications

The NE40 provides two types of OC-3c/STM-1 POS optical interface boards: CR-P4CF and

CR-P8CF.
