Clear uninterrupted communication is impossible without a clear uninterrupted power supply. Protecting telecommunication lines from disturbances caused by inadequate or unstable power is as important as protecting computer data flow. Perhaps even more so, because power outages often come hand in hand with natural and other disasters, when the ability to quickly summon help is particularly critical. To protect telecommunication lines from power disturbances, APC by Schneider Electric offers the following two solutions: PowerShield, a DC UPS designed for protecting the customer premise equipment of hybrid fiber-coax, fiber to the home (FTTH), and fixed wireless local loop (FWLL) networks. Magnum VS, a modular, rack-mountable DC power plant for low power wireless, customer premise and distributed network applications.
