1. Introduction
1.1 Fiber Fed Repeater
The JF43 FFR provides a cost effective solution for cell extension coverage and
increased call quality in shadow areas. It is a RF signal transport system that
provides long range RF coverage where it is impractical to install a BTS.
The JF43 FFR is designed to be strategically placed to overcome difficult zoning
issues by allowing the base stations to remain at a central location while placing
antennas at remote locations. RF signals can be transported to remote locations to
expand coverage into areas not receiving service or to extend coverage into difficult
to reach areas such as canyons, tunnels and underground parking lots and roadways.
The JF43 FFR provides a high-tech, highly-efficient service system which enables
high quality communication at low cost, due to the system’s utilization of one optical
fiber core between the DHU and RU supporting full duplex transmission of signals for
both the DL and UL.
