1 GENERAL INFORMATION
The ComFlex-4300 Distributed Antenna System (hereinafter called “ComFlex”) consists of Master Unit
(MU) and Remote Unit (RU). The MU includes the MU Chassis, Power Supply Unit (PSU), Fiber Optical
Unit (FOU) and RF Unit (RFU). With a modular design, it can support up to 8 independent RF inputs and
8 Remote Units. The Remote Unit is a module design which supports 4 independent bands, 700MHz
(lower ABC)/700MHz (upper C), 850MHz, 1900MHz and AWS band.
The low signal transmission loss of optical fiber is applicable for long distance transmission. ComFlex can
support the optical transmission of up to 6.5dBo optical loss, equivalent to 8 miles fiber length.
Main feature:
 Modularized Master Unit supports flexible field upgrade and maintenance.
 Independent gain control for each RF source.
 High MTBF and low noise design with modular PSU and convection cooling.
 RF module supports both simplex and duplex.
 Supports multi-operator and mix mode application.
 Optical link auto gain control.
 Web based GUI for intelligent commissioning and configuration.
