Yokogawa has unveiled its AQ1210D dual-purpose OTDR (optical time domain reflectometer) for both single-mode fiber and multimode fibre networks.
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.
Latin America continues to be a prolific market with very real possibilities of expansion for FTTH deployment.

The unique challenges brought by the pandemic and modern technology are driving significant and varied changes worldwide in how cable television network operators use technology.
Broadband networks are undeniably at peak demand, with the current global crisis providing the industry with its own ‘new normal’, with consumer’s altered perception of ‘normal’ bandwidth levels.
Complementary metal-oxidesemiconductor (CMOS) technology has come a long way since its invention in 1963 by Frank Wanlass during his time employed at Fairchild semiconductor.
While there has long been a recognised need for fair and reliable connectivity for all, the current pandemic has accelerated the urgency at which this must take place.
