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.

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.
