PON optimized

Excellent hardware performance and advanced analysis algorithm enable the AQ1210 to accurately characterize Passive Optical Networks (PON) through high-port-count splitters (up to 1 × 128)*.
The AQ1210 assists beginner/expert users in simply configuring OTDR measurement settings based on PON topology information for optimal results. Short event dead zone and high sampling resolution enable users to detect as close as 0.5 meters (<20 inches)*.
*Typical, with AQ1215A/E/F and AQ1216F

From completely OFF to measurement ready in under 10 seconds!


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 trace.

High-speed, high-performance real-time measurement

Yellow: Real-time (Hi-Speed), Blue: Real-time (Hi-Reflection), Red: Averaged (Hi-Reflection)


Multi-fiber measurement

Measurement conditions of up to 2000 cores are managed in a table, allowing efficient measurement of multi-fibers.
For each core number, OTDR measurement, loss measurement and fiber core surface image can be saved.
Cores that have been measured are highlighted in color and saved data can be shown in the preview window by selecting the core number in the table. This prevents unintended omission in core measurements and reduces your working time at a site.

OTDR view mode

traceThe 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 trace 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.

OTDR view mode


Loss test

Use the light source and optical power meter to measure optical loss.*1

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.


Auto loss test function*2

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 automatically; therefore, the loss measurements can always be performed at right wavelengths.

Auto loss test function


Multi-fiber loss test*2

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.

Multi-fiber loss test

*1: /SPM or /HPM option is required.
*2: AQ1210, AQ1200, and AQ1100 with /SPM or /HPM option can be used.


PON power measurement*3

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.
*3: /PPM option is required.

File transfer and remote control

AQ1210s can be controlled remotely by using an external device through a USB cable or Wired/Wireless LAN*.
* Conversion adapter using USB port is required

File transfer and remote control

Web browser function

The AQ1210 series have a web server feature, so file transfer and remote control are possible using a web browser on an external device without worrying about the OS of the external device.

AQ7933 Emulation software

Software to display and analyze the trace data measured on an OTDR. It can also create and output reports of analysis results on a PC. Equipped with the remote controller and file transfer applications, this is a more powerful tool to assist your work.

Data transporter

By using the data transporter, the AQ1210’s data files are able to be saved to cloud storage or be attached to an email by a mobile device connected to the AQ1210 with wireless LAN.

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.


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: Dl-1000-B2/ Dl-2000-B2 (Lightel)

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.

Smart Mapper



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.



Enlarging the trace window

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