Safety Precautions for Laser Protection
When installing or maintaining equipment, follow the laser safety precautions to ensure the safety of personnel and equipment.
Laser safety risks include:
- Personal injury
- Equipment damage
Personal Injury
The laser emitted by an optical module is an invisible infrared ray, which may cause permanent eye injury. Do not look into the optical module during device maintenance.
Equipment Damage
To prevent equipment damage when you handle the equipment, follow these precautions:
- When not in use, the optical interfaces on the equipment and fiber connectors on fiber jumpers must be covered with dust-proof caps.
- After removing a fiber jumper that connects to an optical interface on the equipment, cover the optical interface and the fiber jumper connector with dust-proof caps.
- When performing a hardware loopback test by connecting a fiber jumper to an optical interface, add an attenuator to prevent the risk of damage to the optical module caused by excessively 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 excessively strong optical power.
- Unless necessary, do not remove or insert the modules connecting to fibers.
