The test and measurement business of Yokogawa has launched three new optical time-domain reflectometer (OTDR) modules for its AQ7280 series. These new modules expand the range of applications that the Yokogawa AQ7280 OTDR can address.

The Yokogawa AQ7280 OTDR satisfies a broad range of test and measurement needs when analysing optical networks, and is designed to enable field technicians to make fast and precise measurements of optical fibres with confidence.

The three new modules are;

Yokogawa has expanded its multi-application test system (MATS) with a range of optical attenuation and switch modules for applications involving GI50 multimode optical fibre.

Multimode optical fibre has a much larger core diameter than singlemode fibre, which simplifies connections and allows the use of lower-cost electronics such as light-emitting diodes (LEDs) and vertical-cavity surface-emitting lasers (VCSELs) operating at 850nm and 1300nm wavelengths. It is ideally suited for communication over short distances, such as within a building or on a campus.

Yokogawa has introduced a new version of its successful AQ6373 optical spectrum analyser incorporating a new monochromator with a sharp passband filter edge plus a number of new features including a double-speed measuring mode, a multipeak/bottom search function and a data-logging function.
