The JDSU HST-3000 equipped with the Wideband Copper II (WBII) Service Interface Module (SIM) delivers comprehensive copper testing, including the special requirements of very high-speed digital subscriber line (VDSL), in a rugged, modular platform ideal for field use.
Providers face a significant challenge when implementing VDSL as part of various fiber (FTTx) deployments because the copper plant traditionally has not been qualified to withstand the stringent needs of VDSL service delivery. The new spectrum that VDSL uses expands the use of the installed plant into unfamiliar territory. Early VDSL testing has shown that the plant is susceptible to impulse noise not encountered in the current ADSL usage spectrum. In addition, the detection of short bridged taps, which create a much greater impact on VDSL signals than on asymmetric digital subscriber line (ADSL) signals, becomes much more critical in VDSL testing.
While experts disagree on the merits of pre-qualification of copper loops in preparation for service deployment, until now most have considered any wideband qualification in ADSL deployments cost prohibitive. However, in VDSL deployments where high-value triple-play services are carried, pre-qualification generally is considered possible and required for the access plant. The HST-3000 incorporates a rugged, weather-resistant design and long battery life that are ideally suited for use in the field and its modularity allows for field upgrades to support new testing requirements. The HST-3000 is easily upgradeable with technologies and advanced options that support the changing needs of service installers and its dynamic configurability allows it to be used by different technicians with different responsibilities to perform a variety of tests. Standard Ethernet,
Universal Serial Bus (USB), and serial connections offer flexibility to easily download software and offload captured test data.
