Physical Description

Horizon Compact Release 1.01.01 Wireless Ethernet Product User Manual – Volume 1

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 re-terminated to A T & T GigE standards . The same Transtector type

used in an AirPair ODU installation may also be used.

Table 3-2 Port 2 Power Cable Wire Gauge

These values are true for all radio variants and based on a minimum voltage of 35 V DC at the Horizon.

Distance from Power Supply to Horizon Unit 50 m

100 m

300 m

Minimum wire gauge required (AWG) 20 16 14 12

Note that the power wires in the AirPair ODU modem composite cable are 16 AWG, which supports the

maximum length (100 m) when out-of-band management is employed using the combined CAT5 cable.

3.2 Lightning Protection

The Horizon Compact is protected from cable transients and power surges caused by lightning, or other

sources, by means of internal surge arrestor components and external housing grounding points (See

Section 8.0). For the copper interface variant, protection of the connected network is provided by a

proprietary DragonWave PonE power integrator/surge suppressor unit, into which the Ethernet cables are

plugged. The power integrator/surge suppressor is located outside the network equipment enclosure,

close to the network switch/router connection point .

The optical variant requires the power feed and the Port 2 management connection (if used) to be

connected via a Transtector surge suppressor to protect power and network circuits.

3.3 Dual Polarity Radio Mount (DPRM)

The DPRM system allows two Horizon Compact units to be assembled to a single antenna. The antenna

used is no different to that used for a single unit. One Horizon Compact unit is mounted for horizontal

polarity and the other for vertical polarity. Both units can transmit and receive simultaneously. This allows

a link to carry up to 800 Mbps of Ethernet traffic. Although both units can operate on the same frequency

channels, with 30 dB isolation, it is recommended that different frequency channels be used for each unit.
