Detailed Product Description
Single-Band Fiber Optical Repeater
Model: KR-4365F
Introductions:
The
Fiber Optical Repeater is designed to solve problems of weak mobile signal,
which can expand more coverage than RF repeater and reduce investment for the
areas where is fiber optic cable underground.
The
system consists of two parts: Donor Unit and Remote Unit. The Donor Unit
receives the BTS (Base Transceiver Station) signal via open air RF transmission
or direct coupler closed to BTS, then converts it into optical signal, and
transmits the amplified signal to the Remote Unit via fiber optical cable. The Remote Unit will reconvert the optical signal
to the working frequency and provide the signal to the areas where network
coverage is inadequate. And the mobile signal is also amplified and retransmitted
to the BTS via the opposite direction.
Features
Aluminum-alloy casing with IP65 protection
has high resistance to dust, water and corroding;
Tx/Rx control and alarm can be transmitted by
one fiber optical cable;
Stable and improved signal transmitting quality;
One Donor Unit can support up to 16 Remote
Units to maximize utilization of fiber optical cable;
USB or RS-232 port provides a link to a
notebook for local supervision or to the built-in wireless modem to communicate
with the NMS (Network Management System) that can remotely supervise repeater’s
working status and download operational parameters to the repeater
Applications
To expand signal
coverage or fill signal blind area where signal is weak or unavailable.
Outdoor: Airports, tourism regions, golf courses,
tunnels, factories, mining districts, villages, etc.
Indoor: Hotels, exhibition centers, basements,
shopping malls, offices, parking lots, etc.
