Ando AQ7250 with AQ7254B Single-mode mini-OTDR
● Wide dynamic range and short dead zone
The AQ7255B Single-mode Fiber Optical Unit (wavelength: 1.31/1.55μm) provides a dynamic range of 45/43 dB (typ.), enabling measurement of cables over extra-long distances, a function not available on previous models. In addition, the instrument’s short dead zone can detect reflection as close as three meters away and loss measurement at eight meters.
● High-speed, single-button measurement
Automatic measurement with single-button operation in just over 10 seconds (B-type unit).
● Fast response
The screen updates a minimum of two times per second in preview mode, and allows real time checking of changes in the state of optical fibers in less than a second (twice as fast as previously).
● Measurement of lines with large reflection
Reflections too large to be measured became measurable (using average rate of divided high reflection). The Singlemode Fiber Unit can measure return loss of near-end up to approximately 18dB.
● Compact and lightweight
The compact B5 file-size AQ7250 weighs only 3 kg (approx.).
● Large color LCD
The large 7.2-inch color LCD allows easy viewing of measurement values and waveforms. Background color of the display can be selected.
● Long battery life
On batteries, the instrument has an operational life of approximately eight hours under normal service conditions, allowing a full day’s work on one charge. Recharge time is approximately four hours.
● Corresponds to various fibers and wavelengths
• Three-wavelength unit corresponds to 1.625 μm
This unit can measure 1.625 μm WDM line, as well as 1.31/1.55 μm.
• Multi-mode unit corresponds to 0.85/1.30 μm
● Overview display function
The overview display function visually indicates which portion of a data waveform under measurement is being displayed.
This function is useful for observing enlarged waveforms.
● Stabilized light-source mode
In stabilized light-source mode, the instrument can also be used as a light source.
● Stores huge volumes of measurement waveforms
The use of a PCMCIA hard disk card (option) and IC memory card (option) makes up for any shortfall in the storage capacity of the floppy disk for measurement waveforms.
● Simplifies data processing
Use of the optional AQ7931B OTDR measurement data tabulation software allows you to reproduce waveform data recorded by the OTDR on a PC screen for analysis. In combination with the report preparation function (another built-in feature), this software makes it easy to prepare reports. The measurement data can also be output in a format compatible with commercial tabulation software.
● Also supports a keyboard and mouse
The main unit can be operated using an optional mouse.
● Supports a range of optical connectors
Various optical connector adapters can be used to enable quick and easy swapping of optical connectors
