BRMF55 - TETRA OPTICAL MASTER REPEATER

This TETRA master repeater is intended for use to convert signals from RF to optical and supply the remote optical slave repeaters. Typical applications are: long tunnel sections, in-building systems, large area outdoor coverage and long distance feed areas where the cost of the traditional RF cable is more expensive than the economical optical fiber solutions. Using WDM (Wavelength Division Multiplex) technology the uplink and downlink signals are going on he same optical cable. The same optical cable is used for the remote supervision and alarm handling functions, which results a reliable control of communication link. All the slaves (including theirs optional external alarms) and the master unit can controlled through the master unit with a direct connection or by the help of one GSM modem. https://www.bhe-mw.eu/sites/default/files/documents/datasheet/brmf55.pdf
