JDSU Solution Allows Critical Fiber Tests Without Service Disruption

  • JDSU
MILPITAS, CA - JDSU introduced a test solution that allows network operators to conduct critical fiber optic network testing without disrupting customer service. Available on the T-BERD/MTS-8000 field test platform, JDSU's In-Service PMD analyzer qualifies fiber optic networks and tests polarization mode dispersion (PMD), a common impairment factor, without having to shut down links or reroute live traffic.

Measurement of PMD is critical because it impacts the speed with which data can be transmitted and causes problems such as increased bit error rate and packet loss. Unlike competing solutions that require extra equipment and traffic to be shut down or rerouted, JDSU's I-PMD can measure PMD inside live traffic streams without suspending voice, video or data services, reducing operating expenses while improving customer service.

JDSU's I-PMD was developed in collaboration with a leading U.S. Tier-1 telecommunications service provider. The I-PMD test analyzer can be placed anywhere in the network at any time and gathers data on PMD, in-band optical signal noise ratio and transmission problems. It simplifies fiber optic network testing at a time when a growing number of high-bandwidth applications and the migration to 10G, 40G and 100G transmission speeds are adding network complexity.

"With new applications being delivered to customers every day, communication service providers are requiring a more sophisticated way to measure key performance metrics from live traffic in order to deliver the highest-caliber customer experience," says Enzo DiLuigi, vice president and general manager in JDSU's Communications Test and Measurement business segment. "JDSU's I-PMD solution quickly identifies risks to service degradation and outages and virtually eliminates network downtime, which are top priorities for network service providers."

In addition to its unique capability to monitor a network without shutting it down, JDSU's I-PMD also captures all relevant data in a single snapshot, reducing the time it takes to troubleshoot an issue. I-PMD cuts the number of technicians required to troubleshoot a problem in half and reduces the number of test instruments for a technician to carry by three.
