Using Lasers Safely

Using Lasers Safely

When installing and maintaining the equipment, follow the laser safety precautions to ensure the safety of personnel and equipment.

Laser safety precautions include:

  • Personal injury
  • Equipment damage

Personal Injury

The laser emitted by the optical transceiver is invisible infrared ray, which may cause permanent damage to human eyes. Do not look into the optical transceiver during device maintenance.

Equipment Damage

To prevent equipment damage when you handle the equipment, be aware of the following precautions:

  • The optical transceivers on the equipment or the cables, which are not used, must be covered with protective caps.
  • When removing the cable that connects to the optical transceiver on the equipment, cover the optical transceiver on the equipment and the cable with protective caps.
  • When you perform the hardware loopback test by connecting the cable to the optical transceiver, add an attenuator to avoid damage to the optical transceiver as a result of strong optical power.
  • When using the optical time domain reflectometer (OTDR), disconnect the cable between the peer equipment and the local equipment to avoid damage to the optical transceiver as a result of strong optical power.
  • Do not remove or insert the optical transceiver connecting to cables at will.
