PBE D-CSF 3604 Optical channel-selective remote unit, frequency 380-385/390-395 MHz, power supply unit -48 VDC, wall-mounted housing, single fibre optic cable, Cobra-B01

Note:

Due to the discontinuation of the old PBE-H40/H50 controllers, this repeater is equipped with the new PBE Cobra controller. This is not compatible with the old controller generation in the OMU.
If this repeater is to be operated on an old existing OMU, the OMU in question must also be equipped with a new Cobra controller. The existing repeaters can still be operated on the OMU.

D-CSF3604

Digital channel-selective fiber optically powered TETRA amplifier with fixed channel bandwidth of 60kHz and 90kHz. 
A later change to other bandwidths is not possible with this model. 
Factory setting is 60kHz and 90kHz. 
The device can also be equipped ex works with a channel bandwidth of 30kHz. Please contact us for more information. 

Main features:

The D-CSF3604 is a channel-selective fiber optically powered amplifier for TETRA. It is part of a system that is fed by an optical master unit (OMU). The maximum permissible optical attenuation is 10dB opt. This corresponds to a fiber length of 20km between the OMU and the furthest supplied fiber optically fed amplifier. This offers great flexibility when implementing radio coverage for areas that cannot be supplied via an air interface. The fiber optically connected system can be both monitored and controlled. This is done with a very effective software application, the Axell Wireless Element Manager.

Automatic optical gain adjustment

The gain adjustment in the downlink is done by measuring the power level of a pilot tone sent by the optical master unit (OMU). This received power level is subject to constant monitoring.
