Figure - IDU-CPE-DC top view

IDU-CPE-DC is an indoor DC/DC injector. It greatly reduces complexity of the deployment in the cases where DC source is available thus reducing both capital expenditures and total cost of ownership. It is desinged for all CPE units (Smn and Lmn) and has integrated lightning protection. The source of DC power supply can be +48 V or even -48 V, hence installation of CPE units is possible where other DC or AC power sources are unavailable.
