Horizon Compact Release 1.01.01 Wireless Ethernet Product User Manual – Volume 1
5.2 Optical Interface
In the copper interface version, power is fed to the Horizon using PonE techniques via the Ethernet
connection to Port 1. In the optical version, this is not possible, so power is fed via the connection to Port
2. Port 2 on the optical interface variant is equipped with a weatherproof MIL style multi-pin connector,
which incorporates an Ethernet connection and a power feed (NOT PonE) connection. Connection to Port
2 is achieved using a short ‘Y’ adaptor cable, having an RJ-45 connector on one leg, and power tails on
the other. The Ethernet connection to Port 2 provides for optional out-of-band management and the
power tails allow a power feed to be spliced into circuit. Note that the Ethernet connection and power feed
to Port 2 must be fed via a Transtector unit to protect the network and power systems from transients.
As an alternative, an existing AirPair ODU composite power and Ethernet cable assembly, which is
compatible with the Horizon Port 2 connector, may be used, provided that the RJ-45 connector (grey
CAT5) at the Transtector end is terminated as shown in Figure 5-3. The same Transtector type used in an
AirPair ODU installation may also be used.
