JDSU introduces all-in-one test tool for metro and FTTX deployments

DECEMBER 17, 2009 -- JDSU has introduced a field-interchangeable, single-slot optical time-domain reflectometer (OTDR) module for the T-BERD/MTS-4000 platform.

DECEMBER 17, 2009 -- JDSU has introduced a field-interchangeable, single-slot optical time-domain reflectometer (OTDR) module for the T-BERD/MTS-4000 platform. According to the company, the module supports cost-effective deployment and support of metro and FTTX by combining OTDR, power meter, and laser source capabilities in a single instrument.

With all the features of the T-BERD/MTS-4000 -- including a large transreflective touch-screen display, visual fault locator (VFL), and inspection scope -- the metro access (MA) mid-range OTDR adds the following performance characteristics:

  • a stabilized light source and power meter option for insertion loss measurement, to help reduce the number of tools in the field
  • PON-optimized dynamic range for testing through splitters
  • the ability to perform in-service testing -- all OTDR lasers are coupled into one port so a separate port is not required for live fiber testing (a filtered version tests live fibers at 1,625 nm or 1,650 nm)
  • traffic detection that will alert the user if they have connected to a live fiber and inhibit the transmission of any test pulse down the fiber
  • an automated bend detection mode that enables immediate identification and location of macro and micro bends


"JDSU continues to bring to market innovative fiber field test solutions that meet the performance requirements of FTTX, CWDM, and triple-play services being deployed worldwide," says Enzo di Luigi, general manager in JDSU's Communications Test and Measurement business segment. "As a result, our T-BERD/MTS family of products has become the industry-leading solution for field service teams worldwide and our OTDRs are already successfully deployed at many of the world's largest telecom operators."
