Pulse introduces its Excelsus brand B-V175 twisted pair to coaxial balun that allows DSL or home phoneline networking frequencies to be transmitted from twisted pair to coaxial mediums, and vice versa, to support VDSL2 and HomePNA 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 IPTV.

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

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 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.
