BriteCell™  FAST is designed to be simple and easy to install and commission. It requires a 
minimum number of tools and equipment. However, it is necessary to observe local regulations 
when planning and implementing an RF system and safety conventions must be strictly adhered 
to at all times. Particular attention should be paid to the presence of optical lasers, which can 
represent the only potential hazard related to the use of BriteCell equipment. A working 
knowledge of optics, and the safety procedures in their use, is required by the installation, 
commissioning and maintenance staff.  

TFLF local units should be placed as near as possible to the BTS or the RF repeater and should 
be easily accessible as they provide visual alarm information for the system maintenance. 
 

ü  The position of the remote unit should be vertical to maximize thermal dissipation. 

ü  There should be easy access to the optical and RF cables.  

 

The most efficient locations for the TFAF remote transceivers will minimise the number of 
antennas required, while maintaining the coverage level goal. 
 

ü  The position of the remote unit should be vertical to maximize thermal dissipation. 

ü  There should be easy access to the optical and RF cables.  

 
The  passive antenna’s placing should be chosen provide the maximum indoor radio coverage, 
and should be mounted at a minimum height of 2.5m from the ground. They should not be 
placed near trees, plants, metal grids or other obstacles, which could disturb their functionality 
and lead to a degradation of the device's performance. 

A  BriteCell™ Fast system has been designed for remote power distribution, but is also possible 
to supply each unit separately at  –48VDC.  A power supply may be distributed in a composite 
cable, copper and fibre, or two separate parallel cables may be run.  A suitable external adapter 
to provide at least 100W at –48VDC must be used. 

 
To avoid damaging the equipment, the following criteria must be used to start up the system: 
 

1. 

Verify all the power supply connections. 

2. 

Verify all the RF connections and power levels at the BTS/Repeater interface. 

3. 

Verify all the optical connections. 

4. 

Switch on the system. 

5. 

Check for alarm status and in case of alarm refer to troubleshooting paragraph. 

 
It is a good rule, when working with the fibre optic components, to always dispose of the 
appropriate screw covers for closure of the optic connectors that are not connected. The 
intrinsic delicateness of an optic connection must be highlighted.  A minimum layer of dust 
causes a notable increase of the insertion loss, therefore: 
 

ü  Always close the optic connectors that are not connected with the appropriate screw covers. 

ü  Always use compressed gas to remove any deposits in the receptacles before closing them. 

ü  Use the appropriate cloths to clean the connectors. 
ü  Do not allow the male connector to come into contact with skin or oily surfaces. 

ü  Should it be necessary to clean the optic connector, only use pure alcohol.
