Quidway® NetEngine 80 Core Router GE Optical Interface Board
Quidway® NetEngine 80 Core Router
Overview
The GE optical interface board of the Quidway
consists of the PIC Gigabit Ethernet (GE) 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 PIC GE interface
implements Gigabit Ethernet MAC layer processing functions and Physical Medium Dependent
(PMD) sub-layer functions, and provides such functions as loopback and environment monitoring.
The GE optical interface board of the NE80 is mainly applied in Ethernet interconnection, reaching
a rate up to 1000 Mbps. Different GBIC modules can be chosen for different transmission
distances.
Specifications
Currently, the NE80 provides one type of Gigabit Ethernet optical interface board: CR-E4GC.
