Yokogawa adds four new models to AQ1200 Series of handheld multi-function OTDRs

Yokogawa has added four new models to its AQ1200 Series of handheld multi-function OTDRs (optical time-domain reflectometers), bringing the total number of products in the range to seven. The new instruments, which include one triple-wavelength model and three high dynamic range versions, are particularly relevant to FTTx (fibre to the home etc.) applications, and mean that Yokogawa can now offer a complete product line up to satisfy virtually all the differing requirements for installation and maintenance testing of the various types of optical fibre networks in different European countries.

The new AQ1200E is a triple-wavelength instrument that offers testing at the standard in-service wavelengths of 1310 and 1550 nm for testing network quality at the installation stage. In addition, for maintenance test purposes and to prevent interference with in-service signals on active networks, a third wavelength of 1625 nm is used in conjunction with a cut-off filter. As a result, it provides a complete cost-effective package for both installation and maintenance applications on live networks.

The other three new models - AQ1205A, AQ1205E and AQ1205F - are high dynamic range versions, and all provide up to 42 dB dynamic range for operational testing in passive optical networks (PONs) incorporating up to 64-way splitters. The AQ1205A offers wavelengths of 1310 and 1550 nm, while the AQ1205E and AQ1205F are triple-wavelength models, each with two ports: one for the communication wavelengths and the other for the maintenance wavelength.

A new feature in the AQ1200 Series is the measurement assist function, which incorporates a macro bending search capability, multi-trace analysis, an event marker edit mode, and a multi-core measurement function. In addition to the standard OTDR and fault location functions, the AQ1200 Series offers a number of options including visual fault location, optical loss testing with a light source and an optical power meter, and an Ethernet “ping” test.

Even though a large, easy-to-see 5.7-inch colour LCD display is incorporated, the instruments are small (A5 size) and lightweight (1 kg) for ease of field use.
