JDSU adds handheld tunable laser source to ROADM field test lineup

OCTOBER 8, 2007 -- JDSU (search for JDSU) has announced what it touts as the industry's first handheld, battery-powered tunable laser source, the TLS-55 Smart Optical tester. Designed to support ROADM network test applications, the tester is fully compatible with the JDSU optical spectrum analyzer for the T-BERD/MTS-8000, which uses a new, highly accurate method for measuring the true optical signal-to-noise ratio (OSNR) in reconfigurable optical add/drop multiplexer (ROADM) networks.

JDSU says the TLS-55 is the industry's smallest and most lightweight tunable laser source. The tester is designed for channel routing applications, such as wavelength tracking, in ROADM networks.

The TLS-55 is available in two models. The TLS-55C covers all ITU-T frequencies from 1528.384 nm to 1563.863 nm based on a 50-GHz grid. The additional wavelength of 1510 nm ensures testing of optical supervisory channels (optional). The TLS-55L is the complementary laser source to address applications in the L-band from 1570.42 nm to 1608.76 nm. Additional features of the TLS-55 include an adjustable output power level; a power supply management system with three-way powering; a USB port for remote operation; a robust, shock-proof, and splash-proof design for field operation; and quick-start operation, requiring no warm-up time and reducing testing time.
