AMERSFOORT, Netherlands, Oct. 1, 2012 — Four models have been added to Yokogawa Test & Measurement’s AQ1200 series handheld optical time-domain reflectometers (OTDRs) for FTTx applications.
The triple-wavelength AQ1200E operates at the standard in-service wavelengths of 1310 and 1550 nm for testing network quality at the installation stage. For maintenance test purposes and to prevent interference with in-service signals on active networks, a third wavelength of 1625 nm is used with a cut-off filter.
The AQ1205A, AQ1205E and AQ1205F provide up to 42-dB dynamic range for operational testing in passive optical networks 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 measurement assist function incorporates a macro bending search capability, multitrace analysis, an event marker edit mode and a multicore measurement function.
The systems perform visual fault location, optical loss testing with a light source and an optical power meter, and an Ethernet “ping” test.
