AQ7282M
For multi-mode fibers
The AQ7282M is useful for short-distance measurements where many multi-
mode fibers exist, such as structured cabling in factories and data center networks. As the optional stabilized light source has a guaranteed stability of ±0.15 dB at both 850 nm and 1300 nm wavelengths, it can be combined with the power meter module to measure optical loss.
AQ7286A, AQ7286H, AQ7286J
For optical fiber research and manufacturing
These models guarantee a center wavelength of ±15 nm at all wavelengths, which meets the stringent light source requirements for optical fiber and cable manufacturing. Optionally, a center wavelength of ±10 nm (compliant with IEC 60793-1-40) can be specified. In addition, this model guarantees measurement accuracy and reproducibility for research and manufacturing applications and enables stable inspection measurements.
Proven reliability
PON optimized
Quickly, easily, and correctly measure networks with large losses, such as Passive Optical Network (PON) systems.
In PON mode, simply choose the configuration of the route to be measured on the screen, and the OTDR automatically determines the suitable measurement conditions to set the optimal values. Combined with the high SNR (HSN) mode, the AQ7280 OTDR series ensures high trace quality, even immediately after a large loss caused by an optical splitter.

The AQ7280 OTDR series enables easy file transfer and remote control*1 via USB cable or wired LAN*2. Engineers can add an OTDR to their company’s local network and regularly check the status of an OTDR performing continuous measurement from a distance. If engineers are in an environment that allows external connection to the company’s internal network, they can check the OTDR status regardless of their location.
*1 With a web browser, the AQ7933, or remote command.
*2 /LAN option of the OTDR main frame is required.
Much more than an OTDR
Available for both single tasks or multi-tasks, measurement functions that are required for optical fiber installation, replacement, and maintenance can be installed on the AQ7280 OTDR series of instruments, along with application software to support analysis.
Stabilized Light Source (OTDR unit option)
LS
The light source feature via the OTDR port modulates and outputs light at OTDR wavelength and is used for measuring optical loss in combination with an OPM module or as a light source for optical fiber identification.
*/SLS option is required
Visible Light Source (VLS module)
VLS
Using a visible and continuous/modulated red light laser is an invaluable test option that checks the continuity of patch cords, launch fibers, and short fiber trunks. Breaks and bends in the fiber can easily be identified through visual inspection, as the visible light exits the fiber at the fault events. And since this feature uses a separate port from OTDR/OPM, another fiber is searchable while the OTDR/OPM is in use, which improves work efficiency. A flashing light emission is also available.
*Available on AQ4780, AQ2780V, or AQ2781V
Power Checker (OTDR unit option)
OPC
dB/dBm/mW
Power Checker is an optical power meter integrated via the OTDR port and is used to check optical power before making an OTDR measurement. As it uses the same port as the OTDR, there is no need to switch ports.
*/PC option is required
Only port 1 supports this feature, however AQ7282M, AQ7286A, AQ7286H, and AQ7286J are not supported
Optical Power Meter (OPM module)
OPM
dB/dBm/mW
Fiber inspection probe
Fiber surface image display (standard feature)
Scratches and dirt on a fiber connector's surface can cause communication network failures, optical fiber deterioration, and can significantly affect OTDR measurement results. A video fiber inspection probe* enables visualization of a fiber connector's surface for inspection of defects.
Fiber surface test function (option)
This feature automatically analyzes scratches and dirt on the fiber's surface and makes a PASS/FAIL judgment based on either IEC 61300-3-35-compatible criteria or other decision criteria dictated by the user. The surface image and judgment results are savable and available as PDF reports.
*/FST option and a recommended optical fiber inspection probe are required
*This feature is not available for multi-tasking
A modular optical power meter that attaches to the main frame, the OPM module supports a wide range of applications such as wavelength setting in 1 nm increments, modulation signal measurement, and multi-fiber measurement. It is usable with the stabilized light source (OTDR unit) for loss measurement and can also measure video services such as CATV and long distance transmission lines where an optical amplifier is used to boost the optical signal power.
*Available on AQ2780, AQ2781, AQ2780V, or AQ2781V
Multi-tasking
Functions other than OTDR can be used at the same time by activating them from the OTDR measurement screen. This unique multi-tasking feature reduces measurement idle time during and revolutionizes the test process by enabling simultaneous parallel testing instead of serial testing. Stabilized light source, visible light source, power checker, optical power meter, fiber surface image display, and optical switch box are available for multi-tasking.
*The OTDR, the stabilized light source and power checker functions cannot be used simultaneously. Fiber surface image display and optical switch box functions cannot be used simultaneously.

AQ3550 Optical Switch Box
The AQ3550 12-ch optical switch box for SMF works in conjunction with an OTDR. Control and power supply are performed from the OTDR main frame, while the optical switch box enables continuous measurement of all or a selection of the 12 channels. It is useful when measuring multiple fibers, such as optical fiber tape, under the same conditions.
*AQ3550 is not available with AQ7282M
AQ7933 Emulation software
The AQ7933 emulation software displays and analyzes trace data measured on an OTDR and creates and outputs analysis reports via PC. Users can upload up to 1000 traces and the SOR software function sets events or markers on all loaded traces collectively.
*The AQ7933 can be downloaded from the YMI website. We offer a trial version of the software, in which all the functions are available for free for a trial period.
AQ7940 Optical fiber monitoring software
The AQ7940 optical fiber monitoring software enables monitoring and detection of momentary interruptions on optical fiber networks. It detects interruptions of 200 ms or longer and automatically saves trace data before and after the detection. This PC application software allows users to search for the location of an interruption, something that previously was tedious and difficult to do.
*Use USB or Ethernet to connect a PC and the AQ7280. To use Ethernet, /LAN option of the OTDR main frame is required
