Quidway® NetEngine 80 Core Router
OC-48c/STM-16c POS Optical Interface Boards
Overview
The OC-48c/STM-16c POS optical interface board of the Quidway®NetEngine 80 core router
(abbreviated to NE80) consists of the PIC OC-48c/STM-16c 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-48c/STM-16c POS
optical interface mainly implements POS frame encapsulation/decapsulation of data flows and
SDH/SONET mapping/demapping of POS frames, provides 2.5-Gbps external optical interfaces,
and enables such functions as loopback and environment monitoring.
CR-P1UZ
The OC-48c/STM-16c POS optical interface board uses fixed optical modules and reaches a rate
up to 2.5 Gbps. You can choose the optical modules according to networking requirements.
Specifications
The 1-port OC-48c/STM-16c POS optical interface board of the NE80 can be further categorized
into four types based on the transmission distances of the used fixed optical modules. The
specifications are listed below.
