The RA-5J00 Tri-band Distributed Antenna System (hereinafter called "RA-5J00") consists of Master Unit
(MU) and Remote Unit (RU). MU is made up of main unit, duplexer unit and optical unit. The system
supports 800MHz and LTE2600MHz which can upgrade 700MHz LTE band in future, suitable for iDEN,
GSM, WCDMA, LTE signal coverage. It‟s advanced monitoring function helps users remotely monitor and
control the device parameter and status inquery through Ethernet, at the same time, users can also locally
configure the device through PC.
The low signal transmission loss of optical fiber is applicable for long distance transmission. RA-5J00 can
support the optical transmission of up to 10dB signal transmission loss.
Main feature:

High power bandwidth linear PA ensures signals no distortion amplification.

Optical fiber transmission with long distance transition at the most path loss of 10dB.

Has AGC function, automatic compensates path loss.

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 MU and RU is
realizable through the integrated wireline/wireless modem, which makes it convenient for on-site
configuration.

Operation Maintenance Center (OMC): real time monitor, set and inquire device status information.

Build-in Li-ion battery ensures that alarm information can automatically report to OMC in case of
equipment power failure.
