Module masters optical dispersion
measurement
Plug-in module is claimed as industry's most compact and integrated dispersion solution dedicated to field testing fibre optic networks.
JDSU has added an optical dispersion measurement (ODM) module to the options for its T-BERD/MTS-6000 and T-BERD/MTS-8000 Offering chromatic dispersion (CD), polarisation mode dispersion (PMD) and attenuation profile test functions in a single plug-in module, the ODM is the industry's most compact and integrated dispersion solution dedicated to field testing fibre optic networks

Visible solid-state laser adopts telecomms design
The FCD488 is the first telecomms-based visible solid-state laser designed for biomedical, industrial and semiconductor applications.
The module includes a patented solution for CD measurement.
Measuring CD, PMD and attenuation is essential during fibre characterisation, a series of tests performed to identify fibre viability for very high-speed transmission systems (10GigE, 40Gbit/s and higher) in both the installation and maintenance phases.
If not properly managed, CD, PMD and attenuation cause severe performance effects on transmission quality that must operate at peak performance in order to deliver reliable broadband services.

New features for optical fibre test instrument
New additions to an optical fibre test instrument include an optical spectrum analyser, and testers for optical transport network interfaces, and Ethernet transported over SONET or SDH (EoS)
The ODM module's combination of CD, PMD, and attenuation test functions allows technicians to validate the fibre link's compatibility with high-speed CWDM/DWDM systems, including reconfigurable optical add/drop multiplexers (ROADMs).
The performance of each individual function also makes the ODM module ideal for characterising fibre at 40Gbit/s and higher.
"As cable and telecom network operators continue to deploy fibre networks to meet the world's increasing broadband needs, they need the right tools to ensure fibre links operate as flawlessly as possible", says Enzo di Luigi, General Manager of JDSU's Fibre Optics Test and Measurement Group.
"The ODM module meets this challenge by enabling efficiency through an integrated solution and offering the best dispersion performance available in a field test solution - which is needed to test most fibre networks, from short or long distance unrepeated networks to aerial and amplified networks".
Additional performance highlights of the ODM module include the industry's only full-band CD analyser with measurement points in the lower bands (1260-1460nm), very fast CD acquisition time (45 to 70s), test capability through nonbidirectional components (EDFA, filters, and similar components), internal and on-line wavelength referencing, accurate zero-wavelength characterisation on G652 fibre, a single input port for any test configuration, and compatibility with plug-in or battery-powered handheld broadband sources at the far end of the fibre under test.
