Pulse's Twisted Pair to Coaxial Cable Balun Enables Signal Conversion to Support IPTV Deployments


SAN DIEGO --(Business Wire)-- Pulse, a Technitrol Company (NYSE:TNL), a worldwide leader in electronic component and subassembly design and manufacturing, introduces its Excelsus brand B-V175 twisted pair to coaxial balun that allows digital subscriber line (DSL) or home phoneline networking (HPN) frequencies to be transmitted from twisted pair to coaxial mediums, and vice versa, to support VDSL2 and HomePNA(TM) deployments. The balun is easily installed with simple plug-in connections. It matches a 100 Ohm twisted pair cable, which is a balanced signal, to a 75 Ohm coaxial cable, which is an unbalanced signal, without degrading the signal.



Telephone companies transmit their signals over twisted pair wiring. This is the existing home wiring that normally is supplied to a house by the telephone company. A balun is a passive electronic device that converts between balanced and unbalanced electrical signals. With the Excelsus B-V175, the twisted pair telephone or VDSL2 connectors are plugged into one end of the balun and a coaxial cable that is connected to the other end of the balun is plugged into a set-top box. The signal from the phone/VDSL2 line is then able to be used to supply the set-top box and the TV with Internet protocol television (IPTV).

The B-V175 can pass frequencies from 25 kilohertz (kHz) to 30 megahertz (MHz) from twisted pair to coaxial cable with less than 1.5 decibel (dB) insertion loss across the entire frequency band. In addition, the B-V175 has a filtered phone port for plain old telephone service (POTS) telephones.


"This is the first consumer installable balun product on the market to support VDSL2 and HomePNA deployments," said Chad Oblak, Pulse Telecom Division product manager. "With the Excelsus baluns, the telephone company can now utilize coax or twisted pair for VDSL2 and HomePNA deployments."

The B-V175 is the first product in Pulse's family of Excelsus brand twisted pair to coaxial balun family. The product family will include baluns that support the 12MHz to 28MHz and 36MHz to 52MHz HomePNA frequency bands along with custom frequency bands and applications. In addition, Pulse is currently developing baluns for applications such as closed circuit television (CCTV) for security and surveillance.

The B-V175 meets FCC Part 68 standards. The parts are packaged in individual polybags, with prices of $6.50 for volume orders. Unit price may vary depending on configuration and shipping destination. Contact Pulse directly for samples and high-volume pricing. Detailed specifications are available on data sheet EX100 at http://www.pulseeng.com/products/datasheets/EX100.pdf on the Pulse website.

The HomePNA(TM) Alliance develops triple-play home networking solutions for distributing entertainment data over both existing coax cable and phone lines. The Alliance creates internationally recognized, open and interoperable standards and best practices. By providing data rates up to 320 Mbps with guaranteed Quality of Service (QoS), HomePNA technology enables service providers to meet - and drive - the growing demand for new multimedia services such as (IPTV) and Voice over Internet Protocol (VoIP) to the home. HomePNA technology also provides consumers with the many benefits of "no-new-wires" home networking.
