The AQ1200 Multi Field Tester OTDR is a compact and lightweight handheld OTDR optimized for the installation and maintenance of optical fiber cables. Designed with ease of use in mind to simplify field testing, improve work efficiency and ensure qualify results. Seven models are offered, each with unique wavelength(s) based on their specific application.

Product Lineup

AQ1200A1310/1550 nmStandard model with the same wavelengths used for communication services.
Applicable for installation and maintenance
AQ1200B1625 nmModels with a wavelength dedicated for maintenance of live fibers.
A built-in cut filter isolates the maintenance wavelength from the communication
wavelength in order to perform accurate measurements in live networks.
AQ1200C1650 nm
AQ1200E1310/1550, 1625 nmThese tri-wavelength models has two ports. One port offers the communication
wavelengths while the other port is dedicated for the maintenance wavelength. Thus this model is ideal for use in both installation and maintenance applications.
AQ1205A1310/1550 nmThis High dynamic range model can accurately measure the trace even after the splitter in a PON system.Thus this standard wavelength model is highly suited for high port count PON networks with up to 64 ports splitters.
AQ1205E1310/1550, 1625 nmThese tri-wavelength models offers high dynamic range and has two ports. One port offers the communication wavelengths while the other port is dedicated for the maintenance wavelength. Thus this model is ideal for use in both installation and maintenance applications. The high dynamic range feature can accurately measure the trace even after the splitter in a PON system. Thus this is highly suited for high port count PON networks with up to 64 ports splitters.
AQ1205F1310/1550, 1650 nm

In Passive Optical Network (PON) System used in FTTH (Fiber To The Home) it is important to quickly and correctly find a fault in the drop cable that is installed after the splitter. The AQ1200 MFTOTDR’s PON measurement mode (*) is a mode optimized for the measurement of PON with a high-port-count optical splitter and can ensure a quality waveform even if there is a big loss of optical splitter in the line. With a short dead zone, the AQ1200 can distinguish connectors placed as closely as 0.75 m in FTTx, home or office networks.

Find a fiber break point easily and rapidly
Pressing one button initiates a measurement and event search and then clearly indicates the location of a fiber break.
Waveform analysis can be done by simply switching over to OTDR function.

Manual Loss test using light source & optical powermeter *1,*2
After adjusting the optical output power (P1) at the end of launch fiber, measure the output power of fiber under test (P2).

Total fiber loss = P1 - P2 (dB)

High power measurement *2
Allow to measure the high power output of optical amplifier, which is used for video services, such as CATV, and long distance transmission.
*1 : /SLT option is required to use this function. *2 : /HLT option is required to use this function.

light source

Loss measurement with LS & OPM interlock
AQ1200’s light source can transmit wavelength information, so that AQ1200’s optical powermeter can make measurements at a right wavelength at the other end. Moreover, the AQ1200A’s light source and optical powermeter can switch between two wavelengths (1310 and 1550 nm) automatically; therefore, the optical powermeter can make measurements at right wavelengths, changing the wavelength along with the light source.

Measurement result storage and report output
Measurement results can be saved in the internal storage or external USB storage media, and the measurement report can be generated in CSV format.
* : /SLT or /HLT option is required to use this function.

Work as Master & Slave using the
communication fiber

The master unit can share the project information such as the core number table and measurement conditions with the slave unit by sending them through the communication fiber in the cable under test.
* : /SLT or /HLT option is required to use this function.

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

Visual fault location and Fiber identification
The visible light source enables to identify a single core out of multicore fiber and find a break point in a launch area visually.
This feature works even when OTDR is in use, so that you can search for a next fiber to test, while OTDR is measuring one fiber.
* : /VLS option is required to use this function.

The Multi fiber measurement function automatically performs measurements and data-filing according to a pre-established file name table. At worksite, you can execute it by simply selecting a fiber number in the table. The saved waveform can be easily shown in the preview window by selecting the core number in the table. The OTDR Project File Editor included in AQ7932 Emulation Software greatly saves time to create file name table.

If there is a bend in the optical fiber, the long wavelength loss is higher at the location of the bend.
This function uses this characteristic to locate macro bends by measuring the same line at multiple wavelengths.

Remote Control using the same GUI
The AQ1200 can be remotely controlled from a personal computer (PC) through Ethernet* or USB interface.
The remote control software displays a front panel image of AQ1200 on PC, so you can control the AQ1200 with mouse in the same manner as operating the actual instrument.
* : /LAN option is required to use this function.

Fiber end inspection
With a video fiber inspection prove connected to USB interface, the AQ1200 can show an image of the fiber end on the screen to visually inspect scratches and dirtiness. The video image can be saved in the internal memory or external USB storage media.
* : Recommended probe: CI-1100B-YOK or DI-1000-B2 (Lightel)

Event Mapper Function
The Event Mapper is a new function which automatically detects and characterizes events in the fiber under test. In a few seconds, events are displayed on the screen as easily recognizable icons together with their data. The position in the fiber of the detected event is clearly shown in the upper part of the display.
