Milpitas, California and Chicago, June 6, 2006 –JDSU today announced the addition of a 30 MHz (VDSL2) copper test option, available as a field upgrade to existing units, to the widely adopted HST-3000 handheld triple-play services tester.  Specifically designed to meet the test needs of field technicians who install and maintain VDSL access networks, the HST-3000 now enables the deployment of higher bit-rate triple play services, including IPTV and HDTV.  The HST-3000 is also designed to address the challenges of deploying VDSL, typically the “last mile” technology in FTTx networks, across copper networks.  The product will be introduced at GlobalComm 2006 in Chicago, June 4-8 (booth 67040).

The JDSU HST-3000 meets the test applications required by field technicians responsible for access network service installation and maintenance.  It is designed to provide maximum flexibility, through software options and field swappable “service interface modules” or SIMs, to meet specific work group needs.  The HST-3000 can be easily upgraded as technology evolves and its automation features improve work force efficiency in the more complex environment of triple-play service support.

Challenges associated with the deployment of VDSL services emerge because the VDSL technology uses frequency bands in the copper plant outside of the current ADSL usage spectrum.  This makes VDSL services more susceptible to impulse noise (unwanted electrical signals of short duration) and short bridge taps.  Bridge taps are copper wires connected to, but not part of, a direct electrical path between the central office and the user premise.   Detection of short bridge taps 20 feet to 100 feet in length is critical because they dramatically impact digital services carried across copper lines by introducing unwanted disturbances that increase electrical loss.  

“Service providers are introducing IPTV to a growing number of markets, with service levels and reliable performance fast becoming the differentiating factors,” said Jerry Gentile, general manager of JDSU’s telecommunication field services (TFS) Test and Measurement group.  “The addition of VDSL copper test functionality to the HST-3000 puts greater testing power in the hands of field technicians to address the challenges of IPTV deployment.”
