Chapter 3: Safety
Prior to operating the equipment in any way, it is highly suggested the user reads all safety information.
The information in this chapter pertains to safety consideration of OTDRs in general. This product has been designed and tested
in accordance with the manufacturer’s safety standards, and has been supplied in a safe condition.
Information contained in this document must be followed by the user to ensure safe operation and to maintain the functionality of
the product. Failure to follow these safety warnings and cautions may result in harm to the user and/or damage to the instrument.
WARNING
Personnel should always be aware when working with fiber optic test equipment that active fibers may be present and
therefore, infrared optical energy may be present.
WARNING
Never look directly into the end of a connected fiber optic cable or the fiber optic interface of optical test equipment; to
do so may expose the user to laser radiation and may result in personal injury.
WARNING
To Prevent Fire or Shock Hazard:
• Do not install battery types other than those supplied by the manufacturer.
• Do not use the charger without the proper batteries installed.
• Do not expose the battery charger to rain or excessive moisture.
• Do not use the AC adapter when there are signs of damage to the enclosure or cord.
• Ensure that you are using the correct charger for the local line voltage.
• Do not use any other charger than the one provided with this instrument.
• Do not puncture batteries.
• Do not incinerate batteries.
• All batteries should be disposed of in a proper manner.
Failure to follow these caution statements may cause unsafe conditions for the operator and/or equipment, and may void
the warranty.
CAUTION
Fiber-optic connectors are easily contaminated or damaged. The connection to the OTDR is by physical contact types of
connections. Dirty or damaged connectors may impair the instruments capabilities at a minimum, and at worst, result
in the need to return the OTDR to the factory for unwarranted repairs. Prior to making any connection to the unit, ensure
that all proper cleaning procedures have been followed. Use APC Finish Connectors Only -- DO NOT insert UPC connectors
into the optical ports.
CAUTION
The OTDR is equipped with a protection circuit to avoid damage from live fiber connections. Therefore, the instrument
will not operate properly with active fibers. Even with circuit protection, high power output from EDFA’s or other
equipment can damage detectors and should never be connected to the OTDR. If a live fiber is connected to the OTDR
and a scan is attempted, a warning dialog will be displayed as in Fig. 3.1. Immediately remove the live fiber from the OTDR
and press select to clear the message.
