Tyco Electronics Unveils FTTN and FTTC Power Solutions

Tyco Electronics Power Systems Inc. (Dallas, TX) unveiled its new remote-powered offerings for fiber-to-the-node (FTTN) and fiber-to-the-curb (FTTC), the CPS2500D (for the downstream or customer end) and the CPS3200U (for the upstream end). The products use existing twisted pairs to provide remote powering for IP-DSLAMs and other equipment. They deliver power from the upstream site to electronics at the downstream or customer end of a fiber. The CPS2500D and CPS3200U solutions deliver remote power using ±190 V or -190 V at distances to 15,000 ft.

When compared with commercial ac-powered solutions, remote power requires fewer battery/generator sites, thus improving availability while lowering the cost of battery maintenance. It can also speed time-to-market by eliminating the need to run additional ac feeds to each downstream node, and by streamlining the right-of-way approval process with municipal governments.

The CPS2500D is located with the video switching equipment at a site not served by batteries. The equipment is typically placed in a cross-connect cabinet or an optical network unit. The CPS2500D accepts up to 20 power circuits and provides up to 1,300 W. It is designed to operate best from a CPS3200U source, but works with a variety of other upstream equipment as well.

The CPS3200U provides up to 3,200 W to feed multiple downstream nodes. The converter and limiter functions are integrated into one unit. Each module provides two 100 VA, ±190 V or -190 V circuits to exactly match the downstream CPS2500D module. The CPS3200U has full front access for cabling and a simple craft interface to minimize craft training. It is also designed to support easy growth through addition of field-replaceable units, providing greater scalability in shelf or frame configurations.
