Simultaneous Display of Trace and Event Table

J012 Tm Aq7260 02 After performing an Auto Event Search, the trace and event table are simultaneously displayed on the screen. Alternatively, you can choose to display just a trace or event table on the screen. In the event table, symbols enable you to identify the types of events.

Auto Mode Measurement

By combining Auto Set and Auto Save functions, you carry out achain of processes automatically such as the following:

Measurement procedure

J012 Tm Aq7260 03a Automatically detects the conditions of the fiber being measured and automatically sets the optimum measurement condition.
J012 Tm Aq7260 03b Starts measuring the average automatically when the measurement conditions are set.
J012 Tm Aq7260 03c Automatically detects the reflection values, positioning (distance) and the loss incurred when the threshold value exceeds the preset values.
J012 Tm Aq7260 03d Stores the measurement results automatically Into the specified memory.

Trace Fix Function

Tm Aq7260 04 Can quickly and easily compare traces with the trace fix function. This is a convenient function to observe the characteristic differ- ences in multi-core fibers by core, and quickly check where the core was bended, and theloss characteristics.

Multi Wavelength Continuous Measurement

Select the Wavelength to be measured
Tm Aq7260 06
Multi wavelength continuous measurement is a function that allows you to switch the wavelength being measured while keeping the same measurement conditions. This is convenient when you need to measure two wavelengths in a single fiber.

AQ7269 MMF/SMF Module


Tm Aq7265 01Tm Aq7265 01AQ7269 MMF/SMF Module is a measurement module for AQ7260 that supports both multimode and single mode fiber in one unit. As this AQ7269 module supports the measurement of multimode and single mode fiber in one unit, unlike our conventional modules, there is no need to exchange the measurement module when installing, maintaining and evaluating the production of both MMF/SMF optic fibers.

* Supports both multimode/single mode fiber in one unit
* Supports measurement wavelengths of MMF850nm/1300nm and SMF1310nm/1550nm
* The same operations as the modules in the past

AQ7265 SMF Module

Tm Aq7265 01The AQ7265 SMF Module is a measurement module for the AQ7260 that offers support for high dynamic range measurement. The AQ7265 joins the earlier AQ7261 (cost performance model) and AQ7264 (standard model) as an addition to the AQ7260 series lineup. This new module enables long-distance optical fiber measurements and evaluations useful during manufacturing, installation, and maintenance that were not possible with the conventional models.

* OTDR measurement module for 1310 nm/1550 nm at AQ7260 OTDR
* High-end model of dynamic range 45 dB (1310 nm)/43 dB (1550 nm)
* The same operations as the modules in the past
* The same weight and size as the modules in the past
* With built-in stabilized Light source
