Laser Radiation
When handling optical fibers, do not stand close to or look into the optical fiber outlet directly without eye protection.
Use of controls or adjustment or performance of procedures other than those specified herein may result in hazardous radiation exposure.
- A laser transceiver is used in optical transmission system and related test tools. The laser transmitted through unterminated optical fibers or connectors has very high power density and is invisible to human eyes. A beam of light can cause damage to the retina.
- Looking into the end of an exposed optical fiber or broken optical fiber without eye protection from a distance of more than 150 mm (5.91 in.) will not cause eye injury. However, eyes may be damaged if an optical tool such as a microscope, magnifying glass, or eye loupe is used to view a bare optical fiber end.
- Observe the following precautions to avoid laser radiation hazards:
- Only trained personnel are authorized to operate the laser.
- Wear protective goggles during laser or optical fiber operation.
- Disconnect the light source before disconnecting optical fiber connectors.
- Use optical fiber caps to protect the disconnected optical fiber connectors.
- Use an optical power meter to measure optical power and verify that the light source is disconnected.
- Do not look into an exposed optical fiber or connector terminal until the light source is off. Immediately install dust-proof caps onto exposed optical fiber connectors.
- Ensure that the optical fibers and light source are disconnected before fiber cutting or splicing.
- Ensure that there is no laser radiation before opening the front door of the optical transmission system.
- Do not view optical fiber terminals or connectors with a microscope, magnifying glass, or eye loupe.
