Cable Requirements
IDU-ODU cable
IDU–
ODU cable is a 50 Ω coaxial cable intended to interconnect the Indoor Unit with the Outdoor
Uni
t. 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.

CFIP PhoeniX IDU-ODU cable
DC power cable
Due to low power consumption of the CFIP PhoeniX split mount system, there are no special
requirements for the cable used to connect the IDU to the DC power source. Any 2 wire power cable
of good quality which fits well in SAF Tehnika’s supplied 2 pole “screw on” power connector could be
used. The power connector is 2 pole, type 2ESDV-02.
1+1 protection cable
Cable used should be rated Cat6 STP or better and length of the cable should not exceed meters.
For pinouts and further details please refer to Chapter 10.6.
RS-232 Serial Connection
The ASCII console must be connected to the RS-232 serial port. This requires a twisted pair (TP)
cable with common shield (foil and plaited shield); the cable must be suitable for DB-9 connector.
Using a proper cable, the operation is guaranteed for up to 10 m of cable.
RSSI BNC
To connect the digital multimeter to the CFIP PhoeniX ODU RSSI port in order to adjust the
antenna alignment, a coaxial cable with BNC connector on one end and appropriate termination on
other end can be used (see example in
Figure 1.10
).
