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 module is an invisible infrared ray, which may cause long-lasting damage to human eyes. Do not look into the optical module during device maintenance.

Equipment Damage

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

  • When not in use, the optical interfaces on the equipment and fiber connectors on fiber jumpers, must be covered with protective caps.
  • After removing the fiber jumper that connects to the optical interface on the equipment, cover the optical interface and the fiber jumper connector with dust-proof caps to prevent dust.
  • When you perform the hardware loopback test by connecting the fiber jumper to the optical interface, add an attenuator to avoid damage to the optical module caused by strong optical power.
  • When using the Optical Time Domain Reflectometer (OTDR), disconnect the fiber jumper between the peer equipment and the local equipment to avoid damage to the optical module caused by strong optical power.
  • Unless necessary, do not remove or insert the modules connecting to fibers at will.
