Cabling and lightning protection
This section describes the cabling and lightning protection components of a PTP 800
installation.
Lightning protection (ODU platforms only)
The PTP 800 has been tested for compliance to the EMC immunity specifications identified
in
The ODUs for the PTP 800 are fitted with surge limiting circuits and other features to
minimize the risk of damage due to nearby lightning strikes. To be fully effective, these
standard features require some additional equipment to be configured as part of the
system installation.
The PTP 800 Series is not designed to survive direct lightning strikes. For this reason the
antenna and ODU should not be installed at the highest point in a localized area. See
Grounding and lightning protection
RFU to CMU connections
The RFU is connected to the LPUs and CMU using CNT-400 coaxial cable (IF cable).
CMU to network connections
The CMU is connected to network equipment using either a copper data port (100baseT or
1000baseT Ethernet) or a fiber interface (1000BaseSX or 1000BaseLX).
Cable grounding (ODU platforms only)
The ODU, LPUs and IF cable must be grounded to the supporting structure at the points
specified in
Grounding and lightning protection
. One cable grounding kit
) is required at each grounding point.
