2. Overview
2.1. Introduction
RC800-120B series fiber-optic multiplexers are ideal fiber-optic transmission devices for
point-to-point networks, medium-sized and small capacity networks, such as wireless
communication base stations, private communication networks, and switching networks.
The transmission capacity of each optical port is 4 E1 channels.
RC802-120B*2 and RC804-120B* fiber-optic multiplexers can be installed into RC004-16
16-slot chassis to be deployed at the host site. They are usually used to construct the
network at the host site, and working in pairs with standalone RC801-120B or RC805-120B
at the remote site.
2.2. Main Features
• Very large scale ASIC chips ensures low power consumption; 4-layer PCB ensures
high reliability
• Complete alarm indication that can display local and remote alarms simultaneously
• Alarm lock and E1 channel loop-back test capabilities implements convenient operation
and maintenance
• Provides two independent fiber-optic multiplexer units, each of which provides 1 optical
interface and 4 E1 channels. Each RC802/804-120B*2 module can connect to two
remote multiplexers that may not in the same place. The high integration significantly
saves space.
• With modular design, it can be installed into any slot form 1
st
to 15
th
.
• One modular multiplexer shall correspond to one standalone multiplexer at the remote
site.
• Support SNMP management. It can be managed by the network management module
in the MPU slot of RC004-16 chassis. It also supports the management of standalone
multiplexer at the remote site.
