General Overview

Detail BS24X Series

Semirigid

A minimum bending radius of 10 mm (semi-rigid TX) and 3,5 mm (semi-rigid RX) must be

ensured. Fix the system cables at SMA connectors with a torque wrench set to 1,00 Nm and

at SMC connectors with a torque wrench set to 0,35 Nm. Terminate all unused connectors

of the antenna combiners with 50 Ohm load resistors!

Flexi Cabling

Fix the system cables at SMA connectors with a torque wrench set to 1,00 Nm and at SMC connectors with a torque

wrench set to 0,35 Nm. Terminate all unused connectors of the antenna combiners with 50 Ohm load resistors!

The cables have to be routed in such a way that allows the ease exchange of modules (CUs, Combiners and FANs). For

this reason BTS Base-/Extension cabinets which have been equipped with flexible HF cabling in the factory always, come

with a pair of cableretainers fitted left-and right hand side at the bottom of each sub-rack (exception: lowest subrack of a

cabinet). Route the cables, so that the LED-indications of the modules are visible and the test adapter connectors are

accessible. The task of these cable retainers - which are bended sheet metal parts - is to keep those flexible HF-cables in

a neat position which inter-connect subracks. If a customer decides to retrofit an 1th generation base station - which has

not been equipped with cable-retainers -with flexible HF cables, these cables must be loosely fitted with cable-ties
