Guidance Handling Modules & Cables BS-240 / 240 II / 240 XL / 240XL II
3th March 2015
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
