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.
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 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” colour LCD display is incorporated, the instruments are small (A5 size) and lightweight (1 kg) for ease of field use.
