Cables

In order to install the CFM site, the following types of cables are needed:
•
IDU–ODU cable;
•
Cable to digital multimeter for antenna alignment during the installation;
•
Interface cables (E1, Ethernet, V.35);
•
Power cable to the IDU.
In case of necessity, SAF Tehnika can offer the aforementioned types of cables.
IDU–ODU Cable
IDU–ODU cable is a 50 Ω coaxial cable intended to interconnect the Indoor Unit with the
Outdoor Unit. Any type of 50 Ω cable of good quality can be used, the cable should be equipped
with N–type male connectors on each end. There are two N–type male connectors included in
each radio unit delivery that fit RG–213 cables or other cables with a surface diameter of 10 mm.
As the attenuation of the cable is essential particularly at 350 MHz frequency, its usage is restricted,
- the attenuation of the signal should not exceed 20 dB at 350 MHz. Commonly employing RG–
213 type coaxial cable, its length may reach 100 m, LMR–400 type cable may usually reach up to
300 m in length.
