Connecting the Lightning and Surge Protector
The third-party (PolyPhaser) lightning and surge protector for the SDA-1 is implemented in the
following deployment scenarios:
IDU/ODU cable connectivity of 40 meters or more (mandatory)
Deployment of ProST in geographical areas that often experience severe lightning
storms
The lightning and surge protector protects the CAT 5's six used wires (two -48 VDC wires and
four Ethernet Tx and Rx wires) from any electrical surge due to a lighting strike.
The protector is installed outdoors on the CAT 5 cable that connects between the ProST and
SDA-1. In other words, two CAT 5 cables are required: one for the protector-to-ProST
connection and the other for the protector-to-SDA-1 connection.
Warning: Do not install the lightning and surge protector during adverse weather
conditions when the threat of lightning strike is possible.
To install the protector:
1. Connect the protector in the direction according to the labels. The end labeled SURGE
accepts the cable from the ProST; the end labeled PROTECTED accepts the cable from
the SDA-1.
