1 GENERAL INFORMATION
The RA-5200 Tri-Band Remote Radio System (hereinafter called “optical repeater” or “system”)
provides flexible and scalable solution of multi-band, multi-operator coverage extension applications,
such as citywide enhancement, highway, canyons, campus, underground tunnels, airports, convention
centres, etc.
This system consists of Master Optical Unit (MOU) RA-5200-D, Remote Optical Unit (ROU) RA-5200-
O and Remote Radio Unit (RRU) RA-5200-R.
The MOU accommodates slide-in modules that can support up to four RRUs through Fiber Optical
Unit (FOU). The wideband optical link of MOU and ROU can support multiple systems over optical
fiber as well as the O&M communications between ROU and RRU.
The low signal transmission loss of optical fiber is applicable for long distance transmission. This
system can support the optical transmission of up to 15dB signal transmission loss. There is no
isolation problem between TX and RX antennas, which means customer can select the antenna
flexibly according to the real situation, such as directional or omni-directional antenna.
Remote configuration and surveillance is possible through Comba’s OMC remote control and
monitoring system.
Characteristics of RA-5200 are as follows:
•
Broadband optical system: 35MHz for GSM900 band, 75MHz for DCS band, 60MHz for
WCDMA2100 band.
•
High output power with high linearity, which supports multiple carrier operation and ensures the
signal source is of good quality.
•
RF transmission over Fiber Distributed Antenna System – suitable for large scale indoor & outdoor
coverage enhancement.
•
Local Operation and Maintenance Terminal (OMT): operating status and parameters can be set or
monitored by OMT PC locally. And the point-to-point setting and inquiry between MOU and RRU is
realizable through the integrated wireline/wireless modem, which makes it convenient for on-site
configuration.
•
Operation Maintenance Center (OMC): system working parameters and communication
configuration can be set or inquired remotely through the integrated wireline modem. If alarm is
generated, the equipment will dial up to OMC automatically in the mode of SMS or datalink.
•
MOU accommodates slide-in modules that allows flexible and scalable system configuration
•
The ROU and RRU is designed for all-weather outdoor installation - waterproof, damp-proof and
omni-sealed
(IP55).
