Safety Information
Laser Safety
• Detailed description
① Keep the optical ports of the module clean, and cap them when they are not used.
② Prevent the end faces of the optical interfaces of the module from being damaged by hard objects.
③ Exercise caution when removing and reinserting the fibers for the SC optical ports on the module. Do not damage the
ceramic sockets of optical components.
④ The goldfinger unit of the module supports no more than 50 times of removal and reinsertion.
⑤ Laser products that are safe during use, including long-term direct intrabeam viewing, even when exposure occurs
while using optical viewing instruments (eye loupes or binoculars). Class 1 also includes high power lasers that are
fully enclosed so that no potentially hazardous radiation is accessible during use (embedded laser product).Intrabeam
viewing of Class 1 laser products which emit visible radiant energy may still produce dazzling visual
effects,particularly in low ambient light.
⑥ Do not look into fiber end faces without eye protection using an optical meter (such as magnifier and microscope)
within 100 mm, unless you ensure that the laser output is disabled. When operating an optical meter, observe the
operation requirements.
• Output average power
Under normal circumstances, the maximum optical output average power of the optical module is 8.0dBm. In
the abnormal case, output average power of the optical module is less than 11 dBm.
