2 Introduction
The BSF-3604 is a fiber optic fed UHF repeater. It is part of a system that is fed from an Axell
Wireless Optical Master Unit Mk. 2 (OMU II), supporting WDM technology, lowering the number of
fibers needed per system. The maximum optical loss of up to 10dB is allowed over the fiber
interconnecting the OMU II and the most distant last remote unit that the OMU supports. This
offers great flexibility when providing RF coverage in areas where it is not possible to rely on off-air
transmission.
The fiber optic system is easily remotely monitored and controlled by Axell Wireless’ effective
supervision tool, The Axell Wireless Element Manager (AEM).
The BSF-3604 includes automatic optical gain settings, where the gain is adjusted in the downlink
chain by measuring the level of the pilot carrier sent from the OMU II. The level of the received pilot
carrier is continuously monitored.
