Quidway® NetEngine 80 Core Router
OC-48/STM-16 CPOS Optical Interface Boards
Overview
The OC-48/STM-16 CPOS optical interface board of the Quidway®NetEngine 80 core router
(abbreviated to NE80) consists of the PIC OC-48/STM-16 CPOS 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-48/STM-16 CPOS
optical interface mainly implements POS frame encapsulation/decapsulation of data flows and
SDH/SONET mapping/demapping of POS frames, provides 2.5-Gbps channelized to 155M optical
interfaces, and enables such functions as loopback, environment monitoring and information query.
CR-P1RZ
The OC-48/STM-16 CPOS optical interface board is used by the router to converge low-speed
POS interfaces, and can be channelized to 16 155M POS interfaces at most. It usually needs to be
used together with a 2.5G SDH transmission ring network for networking.
Specifications
The NE80 provides 1-port OC-48/STM-16 CPOS optical interface boards using fixed optical
modules. In terms of transmission distances, the board can be categorized into the following two
types:
