The new Yokogawa AQ1210 optical-time domain reflectometer (OTDR) has been re-engineered internally to bring the features and user-friendly operation of the AQ7280 flagship OTDR to the installers and testers of passive optical networks (PON) and fibre to the antenna (FTTA).
The new AQ2200-232 from Yokogawa is a high-performance optical sensor head which joins the company’s range of optical power meter modules (AQ2200-215 and AQ2200-221).
Used in conjunction with the dual-port AQ2200-202 interface module, the AQ2200-232 sensor head is targeted at making accurate measurements in challenging applications such as power testing of laser chips in free space light, I/L curve measurement of laser-diode modules and multicore fibre measurements (with an MPO connector adapter).
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.
The Winter edition of Fibre Systems dispelled some myths when it comes to multimode fibre, and looked at the opportunities it currently presents to the data centre market.

The Covid-19 pandemic has and continues to affect every-day life throughout the world. In the optical communications industry, the first obvious signs were when events began to postpone, cancel and reschedule.
After more than a decade’s work, the prospect of full quantum networks exploiting entangled photons is drawing closer. That’s thanks to the work of researchers like Hee Su Park from the Korea Research Institute of Standards and Science (KRISS).
