OTDR Multi Field Testers

Yokogawa Meters & Instruments Corporation announces that it will release the AQ1200E,
AQ1205A, AQ1205E, and AQ1205F multi field testers in markets other than Japan on June
29. These are new additions to the AQ1200 OTDR*1 series of multi field testers, which are
used to test the physical condition of fiber-optic telecommunications networks.

Featuring high performance and easy handling, our AQ1200 OTDR series multi field testers
are compact, lightweight, and moderately-priced, with all the functions needed in the field.
Among the new models announced today, the AQ1200E, AQ1205E, and AQ1205F each
support three different wavelengths, so that even a single unit can cover installation and
maintenance work for an entire access network (a network between the station and
subscribers). The AQ1205A, AQ1205E, and AQ1205F also feature a wide dynamic range*2
and enhanced waveform quality, ensuring accurate measurements with fiber-optic
communication networks that have a large-port-count optical splitting device with a high
insertion loss.
