AXELL BSF-4004 BSF0038 SERIES REPEATER

PRODUCT DESCRIPTION AND USER’S MANUAL

1 Introduction

The BSF 4004 is a fibre optic fed UHF repeater. It is part of a system that is fed from an Optical

Master Unit (OMU), supporting WDM technology, lowering the number of fibres needed per system.

The maximum optical loss of up to 10dB is allowed over the fibre 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 fibre optic system is easily remotely monitored and controlled by Axell Wireless effective

supervision tool, Axell Wireless Element Manager.

The BSF-4004 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 Optical Master Unit (OMU). The level

of the received pilot carrier is continuously monitored.
