In addition, Airspan offers an optional third-party outdoor, lightning and surge protector that
protects the ODU-to-IDU CAT 5 cable's power and data signals from any electrical surges due to
lighting strikes.
Note: ProST is designed with a built-in lightning surge protection that complies with the
Surge Immunity standard EN 61000-4-5.
DC Power Source
ProST can be connected directly to a DC power supply unit that supplies 10 – 52 VDC (0.2 to 0.9 A;
15W maximum, assuming up to 100-m cable length between ProST and power source).
The ProST-to-DC power connectivity is supported by a splitter cable. One end of the splitter cable
connects to the ProST (using the RJ45-to-DB15 adapter or connecting directly to the 15-pin D-type
port); the other end of the cable splits into the following two wire groups:
One group for the subscriber's Ethernet interface (four wires for the Tx and Rx signals)
One group for the DC power source interface (two wires for +48 VDC and +48 RTN)
Warning: ProST should be powered by a safety approved Class II limited DC power
source with maximum current of 1A.
