    Optical Precautions

    • Terminate all laser transceiver outputs properly before connecting laser inputs.
    • Disconnect the input end of an optical fiber jumper cable before disconnecting the output end.
    • Handle glass fiber with care. Glass fiber can be broken if mishandled.
    • Protect skin from exposed glass fiber. It can penetrate the skin.
    • The BTI7800 Series equipment should be used in a controlled access area. Limit the number of personnel that have access to the optical transmission systems. Personnel should be properly trained on laser safety and authorized, if access to laser emissions is required.
    • Limit the use of laser test equipment to authorized, trained personnel during installation and service. This precaution includes using optical loss test (OLT) set, optical spectrum analyzer (OSA), and optical time domain reflectometer (OTDR) equipment.
    • Exclude any unauthorized personnel from the immediate laser radiation area during service and installation when there is a possibility that the system might become energized. Consider the immediate service area to be a temporary laser-controlled area.
    • The BTI7800 Series system functions in the 850-nm to 1620-nm wavelength window that is considered invisible radiation. Laser light being emitted by a fiber, a pigtail, or a bulkhead connector cannot be seen by the naked eye. Use appropriate eye protection during fiber-optic system installation or maintenance whenever there is potential for laser radiation exposure, as recommended by the company’s health and safety procedures. Observe this precaution whether or not warning labels have been posted.
    • During installation or service, a broken optical fiber or non-terminated connector should only be viewed with an indirect image converter or with a filtered optical instrument of optical density sufficient to reduce the exposure levels below the appropriate maximum permissible exposure, unless it has been verified that all optical transmitters are turned off and will remain off during the installation or service operation.
    • During all splicing operations that require viewing the end of a fiber of an SG3a, SG3b or SG4 optical-fiber communication systems, the laser source on the fiber involved shall be de-energized or viewing the systems incorporating personal protection shall be employed. A responsible person(s) shall verify that the system is de-energized before splicing proceeds. Where applicable, ensure compliance with lockout/tagout requirements of OSHA Standard 29 CFR Part 1910.147.
