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:
