Quidway® NetEngine 80E Core Router

10GE Optical Interface Boards

Overview

The Quidway®NetEngine 80E core router (“NE80E” hereinafter) is based on the 10G platform and

can provide 10G wire-speed Ethernet interfaces.

The NE80E 10GE optical interface boards fall into two types: WAN board and LAN board, whose

differences are as follows:

zThe WAN board encapsulates Ethernet MAC frames in the SDH/SONET frame structure and

then transmits them via optical fibers. It can be connected to the interface of another WAN

board or the SDH/SONET transmission equipment. It is mainly applied in WAN interconnection

of the Ethernet.

zThe LAN board conducts electrical/optical (E/O) conversion of Ethernet MAC frames and then

directly transmits them via optical fibers. It can be connected only to the interface of another

LAN board. It is mainly applied in LAN interconnection of the Ethernet.

The 10G LAN board mainly implements 10G LAN processing and interface functions. The interface

complies with IEEE 802.3ae, implements MAC and Physical Coding Sublayer (PCS) functions and

provides functions such as loopback, environment monitoring and information query.

The 10G WAN board mainly implements 10G WAN processing and interface functions. The

interface complies with IEEE 802.3ae, implements MAC, PCS and Wide Area Interface Sublayer

(WIS) functions and provides functions such as loopback, environment monitoring and information

query.

Depending on the optical module types supported by the interface boards, the NE80E can provide

two types of modules: pluggable XFP optical module and fixed optical module. During the

networking, you can select 10G LAN boards or 10G WAN boards based on the differences between

the two types of boards described above and the current condition of the network, and then select

different 10G optical interface boards supporting XFP optical modules or fixed optical modules

according to the transmission distance.

Specifications

Currently, the NE80E provides three types of 10G LAN boards and four types of 10G WAN boards.

Among them, two types support pluggable XFP optical modules while the other five types support

fixed optical modules. The following table lists the specifications:
