Safety Precautions
Make sure to comply with the precautions below. Not complying might result in injury or death, or damage to the instrument.
WARNING
Use the Correct Power Supply
Before connecting the power cord, ensure that the source voltage matches the rated supply voltage of the AC adapter and that it is within the maximum rated voltage of the provided power cord.
Use the Correct Power Cord
Use only the power cord that comes with the instrument. Do not use it for other devices.
Use the Correct AC Adapter
Use only the AC adapter specified for the instrument. Do not use it for other devices.
Use Only the Designated Battery pack
Use only the battery pack specified for the instrument. Do not use it for other devices.
Use only this instrument or a charger specified by YOKOGAWA to charge the battery pack. If the fast charge does not finish after three hours or more, stop charging the battery pack immediately.
Because the electrolyte solution inside the battery pack is alkaline, harm can be done to the clothes or skin, if the battery pack leaks or explodes and the solution comes in contact. If the electrolyte solution enters the eye, it can cause blindness. In such cases, do not rub the eye. Rinse thoroughly with water and immediately consult your eye doctor.
To prevent the possibility of electric shock and accidents, always turn OFF the power switch and remove the AC adapter power supply from the instrument when replacing the battery pack.
Do not throw the battery pack into fire or apply heat to it. This can cause dangerous explosions or spraying of the electrolytes.
Do Not Look at the Laser Light
Do not look at the laser’s direct ray, reflected ray from a mirror, or indirect ray without the proper protective eyewear. In addition, avoid being exposed to the laser light. It can cause blindness or damage to the eye.
Do Not Operate in an Explosive Atmosphere
Do not use the thermocouple in a location where any flammable or explosive gas/ vapor is present. Operation in such an environment constitutes a safety hazard.
Do Not Remove Covers
The covers should be removed by YOKOGAWA’s qualified personnel only. Opening the cover is dangerous, because some areas inside the instrument have high voltages.
Carrying and Moving the Instrument
Remove all power cords and connection cables from the main unit before moving the instrument. When carrying the instrument, hold it firmly by the handle.
Also, if storage media is inserted into the instrument, always remove the storage media before carrying or moving the instrument. Never leave the media inserted when carrying or moving. The storage media can become damaged.
Apply Correct Signals to the Optical Connectors (PORT1 and PORT2)
Do not apply light that is —5 dBm or greater to the AQ7270/AQ7275 optical connectors (PORT1 and PORT2).
Doing so may damage the AQ7270/AQ7275.

Safety Precautions
CAUTION
When Measuring with the Same Wavelength as the Communication Light
Most instrument models use the same wavelength for measurement as is used for communication. If communication light is present in an optical fiber being measured, this has an affect on the communication itself. Take sufficient precautions to avoid interruption of communications. The measurements by the
instrument may also be incorrect, therefore the measuring environment (presence or absence of communication light, etc.) should be carefully considered.
When Measuring with a Wavelength Different from the Communication Light (1625/1650 nm)
When there is communication light in the fiber under test, use a wavelength different from the communication light for measurement.
If no cutoff filter of 1625 nm or 1650 nm is installed in an instrument connected to the system under test, or depending on the instrument’s lightfastness power rating or characteristics of the cutoff filter such as its attenuation, the pulse light output from the instrument can, in the worst case, damage the instrument. Check that an appropriate cutoff filter is installed and that there is no problem with the instrument’ s ratings, then take sufficient caution during use.
When Using the Angled PC SC Connector (Suffix Code:-ASC)
•Use the same type of angled PC SC connector for the connected optical fiber cable as well.
The ferrule end of the angled PC SC connector is polished to an angle.
If other types of connectors are used, the end face of the connector may become damaged.
•You can replace the AQ7270/AQ7275 connector, but only with an SC type.
See below for operating environment limitations.
CAUTION
This product is a Class A (for industrial environments) product. Operation of this product in a residential area may cause radio interference in which case the user will be required to correct the interference.

Safety Precautions
Safety Precautions for Laser Products
This instrument uses a laser light source. This instrument is a Class 1M laser product as defined by IEC60825-1 Safety of Laser Products-Part 1: Equipment Classification, Requirements and User’s Guide. In addition, the AQ7270/AQ7275 complies with
21 CFR 1040.10 except for the items that deviate from the standard as a result of complying with Laser Notice No.50 dated on June 24, 2007.
Laser Class 1M Label
If the laser output is observed at a distance of 100mm or less from the laser beam emitting part by means of optical method (loupe, magnifying glass, microscope, etc.), this may cause eye injury.
INVISIBLE LASER RADIATION DO NOT VIEW DIRECTY WITH OPTICAL INSTRUMENTS CLASS 1M LASER PRODUCT (IEC 60825-1:2007)
Laser Class 3R Label
Avoid direct eye exposure
VISIBLE LASER RADIATION AVOID DIRECT EYE EXPOSURE CLASS 3R LASER PRODUCT (IEC 60825-1:2007)

Chapter 2 Measurement Overview
2.1Measurement Configuration
Overview of the AQ7270/AQ7275
The AQ7270/AQ7275 is an optical time domain reflectometer that measures optical fiber lengths and losses and identifies failure locations. It is mainly used in the optical fiber installation and maintenance servicing of access networks (communications links
between telephone exchanges and telephone poles) and user networks (communications links between user sites and telephone poles). The light source and optical power monitor functions can also be used as options.

Analysis Using the Emulation Software
The waveform data that is measured by the AQ7270/AQ7275 can be analyzed on your PC using the AQ7932 OTDR emulation software (version 3.0 or later). The software comes with a report creation wizard that is convenient in creating construction reports.
Precautions for Measurement
When Measuring with the Same Wavelength as the Communication Light
Most instrument models use the same wavelength for measurement as is used for communication. If communication light is present in an optical fiber being measured, this has an affect on the communication itself. Take sufficient precautions to avoid interruption of communications. The measurements by the instrument may also be incorrect, therefore the measuring environment (presence or absence of communication light, etc.) should be carefully considered. For details on fiber-in-use alarm function, see section 6.1.
When Measuring with a Wavelength Different from Communication Light (1625/1650 nm)
When there is communication light in the fiber under test, use a wavelength different from the communication light for measurement.
The instrument is designed to allow measurement that impacts communication as little as possible in such cases, but be sure to install a cutoff filter of 1625 nm or 1650 nm in system under test. If measurements are taken without a cutoff filter installed, communications can be affected and measurements may not be correct. Always check the configuration of the system under test before use (presence or absence of an appropriate cutoff filter, attenuation characteristics, etc.).

* Do not bend the optical fiber cable.
There are two optical connectors on the top panel of the AQ7270/AQ7275.Because the connector that delivers the optical pulse is fixed depending on the wavelength, connect the cable to the appropriate connector according to the condition of the optical fiber cable to be measured. You can view the indicator shown on the display (see page 1-5) to choose the appropriate connector.

This also applies when using the optional optical power monitor or light source function.
Note
•The 735021 outputs 1650 nm from PORT1.
•The 735029 outputs 850 nm and 1300 nm from PORT1.
•The /PM option supports only PORT1. PORT2 (MMF) and 1650-nm wavelength are not supported.
When Using the Angled PC SC Connector (Suffix Code:-ASC)
•Use the same type of angled PC SC connector for the connected optical fiber cable as well.
The ferrule end of the angled PC SC connector is polished to an angle.
If other types of connectors are used, the end face of the connector may become damaged.
•You can replace the AQ7270/AQ7275 connector, but only with an SC type.
