Smart Mapper

Single button measurement. Comprehensive network characterization. Easy to read report Measurement acquisitions with multiple pulse widths and smart-algorithm enable users to detect and comprehensively characterize network events by pressing one single button. Simple, icon-based map view for easy interpretation of network events. Immediate PASS/FAIL judgment
based on user-defined thresholds.
Easily toggled trace view for manual supplementary analysis.

Enhancing productivity
Managed by a highly efficient operating system, multiple functions can be performed simultaneously.
Now, users can perform OTDR measurements on a particular fiber core while simultaneously checking the power level, connector surface quality and visible fiber ID/bending on three other fibers.



High-speed, high-performance real-time measurement

When detecting/identifying the position of a fiber end point or bend of an installed optical fiber network, a user, according to the operating environment, can choose among the two modes: the high-speed mode with less measuring time and the high accuracy mode that is capable of reproducing a high-quality waveform.

PDF reporting

Built-in post-processing software for generating OTDR reports in PDF format. Flexible configuration of report template to meet users’ report requirements.


File transfer and remote control

File transfer
The AQ1210’s data files can be transferred to a smartphone or tablet through Wi-Fi using a web browser or the OTDR data transporter, or a WindowsTM PC through Wi-Fi or LAN using a web browser or the AQ7933 Emulation software.

Remote control
The AQ1210 can be controlled remotely by a smartphone or tablet using a web browser and by a WindowsTM PC using a web browser, the AQ7933 Emulation software, or remote- control commands through Wi-Fi or LAN.

Connector quality assurance

Using a video fiber inspection probe*, fiber connector surface is visualized for inspection of scratches and dirt. The Fiber Surface Test function (option) can automatically analyze scratches and dirt and makes PASS/FAIL judgment based on IEC61300-3-35 compatible or arbitrary decision criteria.
*Recommended probe: DI-1000-B2 (Lightel)

Connector quality assurance


Macro bending detector

Macro bending events along a fiber under test can be identified and located automatically by OTDR measurements using multiple wavelengths trace comparison and event analysis based on user-defined thresholds.

Advanced trace analysis

Multi-trace analysis
Up to four traces can be overlaid on the display for analysis and comparison. This is useful for evaluating the locations and loss of connections after installing multiple fibers.

2-way trace analysis
Averages the two traces measured from one end of fiber link and the other to nd the connection loss properly and accurately. When only measured from one end, the connection loss may be shown incorrectly due to the difference in the backscatter coefficient between the connected fibers.

Differential trace analysis
Displays the difference between two specified traces. Makes it simple to check aging of fibers or connection points, or variation in loss among fibers, and other phenomena.

Section analysis (Return loss)
Finds the total return loss in specific section of fiber link. It is often required because the multiple reflections from optical fiber networks can affect the optical communication signal from transmitters of CATV for instance.


OTDR view mode

The OTDR view can be switched between the trace and the map by simply tapping the icon. The trace is a traditional view with an OTDR waveform and event markers, and the map is an icon-based view for easy interpretation of network events, which is also used for the Smart mapper function.

Enlarging the trace window

By simply tapping the dedicated icon, the trace display window can be enlarged for easy viewing and manipulation.

Direct data saving

Simply pressing “Direct save” icon, measured data can be saved in SOR, PDF, or both formats according to users’ prior selection.


Optical loss test using light source & optical power meter

Optical loss test is performed by adjusting the optical output power (P1) at the end of launch fiber and measuring the output power of fiber under test (P2) afterward.

Total fiber loss = P1 − P2 (dB)

Auto loss test function
The AQ1210 can transmit the wavelength information of light source to the other AQ1210 placed at the other end to set the same wavelength for the optical power meter, and they are capable of switching the wavelengths (1310 and 1550 nm) automatically; therefore, the loss measurements can always be performed at right wavelengths
*/SPM or /HPM option is required.

Auto loss test function


High power measurement

The high power optical power meter (/HPM option) can measure the high optical power up to +27 dBm. It allows to measure video services and long distance transmission lines where an optical amplifier is used to boost the optical signal power.


Multi-fiber loss test

The Multi-fiber loss test function incorporates two AQ1210s as master and slave through the communication fiber in the cable under test. They share a test project information including fiber numbers to be tested and measurement conditions, so that you can ensure the measurement is performed properly for each fiber of the cable under test. */SPM or /HPM option is required.

PON power measurement

Simultaneous power measurement at 1490 & 1550 nm
The PON power meter can measure the optical power both at 1490 nm and at 1550 nm simultaneously by separating those wavelengths. It is a suitable tool for measuring the optical power of OLT and V-OLT.
*/PPM option is required.
