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.
