Alpha Technologies Ltd. has released two line power products. The next generation Cordex HP LPS36 is a compact, modular DC to DC up-converter system designed for powering distributed communication networks using ±190 VDC (RFT-V circuit) over an existing copper network. It features modular, high efficiency, quad output converter modules along with an intelligent controller. Applications include powering DSLAM’s as well as the Optical Network Terminals (ONT) in FTTH Networks. The Cordex HP LPS36 can be installed in the central office or in a remote OSP cabinet. Line powering uses the CO or RT backup power system as the source, eliminating the need for AC utility or battery backup at the remote site, thus reducing truck rolls and operating expenses.
The Alpha SR-12190 is a compact DC to DC downconverter that transforms ±190 VDC into 12 VDC for powering the ONT in a FTTH network. Designed for outdoor environments, the compact, self-enclosed design is well suited for mounting on the side of the house, nearby the ONT. It is equipped with a built-in capacitor to ensure continuous operation, even during brief electrical surges. Unlike other downconverters, the SR-12190 provides a 12 V output designed specifically for powering ONTs.
