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
Minimum wire gauge required (AWG)
Note that the power wires in the composite cable are comprised of two pairs of 20 AWG wire, which
supports the maximum length (100 m) when out-of-band management is employed using the combined
CAT5 cable.

Lightning Protection

Note: For effective protection against lightning-induced surges, proper grounding and shielding
practices MUST be followed for the ENTIRE installation. Consult DragonWave Inc. Technical Note:
HC-TN-001.4 Horizon Compact Plus PonE and Quick Reference Guide before installation!
The Horizon Compact Plus is protected from cable transients and power surges caused by lightning, or
other sources, by means of internal lightning arrestor components and external housing grounding points
(See Section 8.0).
For the Horizon Compact Plus, copper interface variant, protection of the connected network and power
supply is provided by a proprietary DragonWave PonE power injector/Lightning Arrestor unit, into which
the Ethernet cables and power feed are connected. There are two variants of the copper power
injector/Lightning Arrestor unit.
•
Copper interface, outdoor use (see Figure 3-3)
o
may be mounted on the outside wall of the network equipment building
•
Copper interface, indoor use, wall or rack mountable (see Figure 3-4)
o
must be mounted inside the network equipment building

Arrestor
For the Horizon Compact Plus, optical interface variant, or where PonE is not used to power the Horizon,
protection of the power feed and the Ethernet connections is provided by a Lightning Arrestor unit of
similar physical design to those described above. For correct installation procedures see Section 4.0.
