Service tester troubleshoots 30MHz VDSL2
Using the UltraFED and an HST-3000, only one technician is needed or VDSL pre-qualification and troubleshooting.
JDSU has added the UltraFED 30MHz far-end device (FED) its range of triple-play service testers Designed to meet the test needs of field technicians who install and maintain VDSL access networks, the UltraFED is fully interoperable with the JDSU HST-3000 and enables the troubleshooting of 30MHz VDSL2, typically the "last mile" technology in FTTx networks

Visible solid-state laser adopts telecomms design
The FCD488 is the first telecomms-based visible solid-state laser designed for biomedical, industrial and semiconductor applications.
The UltraFED combines copper FED test features and process improvement applications using a variety of user-configured test states and modes.
In the past, two high-end test instruments (like the HST-3000) operated by two technicians at each end of the circuit were required for VDSL pre-qualification and troubleshooting.
Using the UltraFED and an HST-3000, only one technician is needed.
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's premises.
Detection of short bridge taps 6 to 30m in length is critical because these gaps dramatically affect digital services carried across copper lines, introducing unwanted disturbances that increase electrical loss.
"The increase in broadband access speeds to accommodate services like IPTV and the associated need to pre-qualify and troubleshoot high-bandwidth copper access networks, have created an ever-increasing strain on service provider field teams", said Jim Nerschook, Vice President and General Manager of JDSU's Telecommunication Field Services (TFS) Communications Test and Measurement business segment.
The JDSU UltraFED puts greater testing power in the hands of field technicians and enables them to turn up and troubleshoot with 'one man out'".
