JANUARY 25, 2007 -- JDSU (search for JDSU) has introduced the OTU-8000, a rack-mounted, remote test unit for its optical network management system (ONMS) that integrates the latest optical time-domain reflectometry (OTDR) and optical switch technologies. Based on JDSU's MTS/T-BERD 8000, a single OTU-8000 can test hundreds of fiber links within a large (40,000 km2) area and report any faults relative to the nearest physical landmark.
The JDSU OTU-8000's wide range of applications help carriers decrease operational costs by eliminating erroneous field technician dispatches, reducing mean-time-to-repair (MTTR), and anticipating service disruption by detecting fiber degradation before service is affected, according to the company. The product also monitors the long-term performance of installed fibers and, for organizations concerned about network security, detects and locates fiber tapping.
"JDSU's ONMS is already ahead of the competition because it ensures that what the telecommunications or cable operator sees in its network map is the same as what is actually in the network," said Enzo di Luigi, general manager of JDSU's Fiber Optics Communications Test and Measurement group. "By adding the powerful OTU-8000, network operators can attain a higher level of reliability, efficiency, and cost savings using a compact test unit that has low power consumption."
The OTU-8000 can house two field-interchangeable OTDR modules and monitors active fibers using a 1625-nm module designed to take into account factors such as the Raman effect of the optical amplifier. The dual-power feeds provide an alternative power input in the event of one power source failure. All configurations are saved on the OTU-8000's solid state disk, and when the server is not available alarms can still be sent directly to the user via e-mail or SMS. Provisioning of the OTU-8000 is easily accomplished using any on-site or remote web browser.
