AQ7275 PON-OTDR
The Yokogawa AQ7275 PON-OTDR is a passive optical network (PON) version of the company's AQ7275 portable, optical time-domain reflectometer (OTDR).
The instrument is designed to overcome the problems traditionally encountered in FTTH (fibre-to-the-home) networks, incorporating passive optical components such as 1 x 32 or 1 x 64 splitters.
Under normal conditions, the losses in trace data across the splitter can compromise the accuracy of the measurements, but with the PON-OTDR, the smooth, low-noise trace ensures quality measurements.
Three models of the AQ7275 PON-OTDR are available to support wavelengths of 1310, 1550 and 1625nm, allowing use at the installation and in-service maintenance stages.
A filter option for the 1625nm version makes it possible to directly check the inline optical network in troubleshooting applications.
A real-time mode function offers a rapid test capability that makes it easy to check the PON network condition within a period of 1sec.
It also allows the user to change parameters such as wavelength, distance and pulse width during real-time operation.
All versions of the AQ7275 PON-OTDR offer a maximum dynamic range of 40dB.
