Meters & Instruments Corporation has
released the AQ1200E, AQ1205A, AQ1205E, and AQ1205F multi field testers. These
are new additions to the AQ1200 OTDR 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 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.
Development Background
To respond to the growing volume of
video and other types of data transmitted over networks, high-speed and
large-capacity fiber-optic telecommunications networks are being installed all
over the world. There is strong demand for OTDRs in emerging countries like
China and India that are rapidly expanding their fiber-optic networks. In
countries such as Japan and South Korea where the fiber-optic communication
infrastructure is already well established, OTDRs are also increasingly in
demand for maintenance work that will ensure communication quality and stable
operation.
Yokogawa also offers a high performance
OTDR fiber-optic tester, the AQ7275. This versatile high-end model can be used
in the installation and maintenance of trunk lines that connect large cities to
access networks. However, for operations that mainly involve the field
maintenance of access networks, a smaller and lighter measuring instrument is
needed.
To satisfy this need, Yokogawa released the compact, lightweight, and
moderately-priced AQ1200 OTDR series in February 2010. Each of the initial
three models in this series has a different measuring wavelength and dynamic
range.
Product Features
All AQ1200 OTDR series multi field
testers are compact (A5 size), lightweight (approximately 1 kg), and come with
various essential functions for the field maintenance of fiber-optic
communication networks. They are just half the size and one-third the weight of
the AQ7275.
These testers all support passive
optical network (PON) systems that branch out optical fibers from stations
using an optical splitter and connect them to multiple subscribers. With PON
systems, a measurement waveform tends to deform due to the attenuation of
optical signals at a splitter. The AQ1200 OTDR series multi field testers can
determine whether any problem is caused by a line failure or signal
attenuation, and can accurately pinpoint failure locations, if any.
The features of the new models are as
follows:
- Supporting three different wavelengths
The AQ1200E, AQ1205E, and AQ1205F models each support two wavelengths for the installation of telecommunication networks and another wavelength for maintenance. Thus, each of these testers can cover both installation and maintenance of an access network.
These testers also have a filter in their optical port that blocks the communications wavelength so that it does not disturb measurements made with the maintenance wavelength. This means that even if OTDR measurement is being performed on a network while it is in use, the maintenance work will not affect communication quality and the network operation will not influence the measurement accuracy.
- Accurate measurement of PON systems
The AQ1205A, AQ1205E, and AQ1205F have a wide dynamic range and enhanced waveform quality, enabling accurate measurements even with PON systems that have a large port count splitter.
