While this DCM is a totally passive device, it typically handles high light levels that can present a hazard,
Laser Safety Procedure
ALWAYS read the product data sheet and the laser safety label before powering the product. Note the operation
wavelength, optical output power and safety classifications.
If safety goggles or other eye protection is used, be certain that the protection is effective at the wavelength emitted by the
device under test BEFORE applying power.
ALWAYS connect a fiber to the output of the device BEFORE power is applied. Power should never be applied without
an attached fiber. If the device has a connector output, a connector should be attached that is connected to a fiber. This will
ensure that all light is confined within the fiber waveguide, virtually eliminating all potential hazard.
NEVER look at the end of the fiber to see if light is coming out. NEVER! Most fiber optic laser wavelengths (1310nm
and 1550nm) are totally invisible to the unaided eye and will cause permanent damage. Shorter wavelengths lasers (e.g.,
780nm) are visible and are very damaging. Always use instruments, such as an optical power meter, to verify light output.
NEVER, NEVER, NEVER look into the end of a fiber on a powered device with ANY sort of magnifying device. This
includes microscopes, eye loupes and magnifying glasses. This WILL cause a permanent and irreversible burn on your
retina. Always double check that power is disconnected before using such devices. If possible, completely disconnect the
unit or transmitter from any power source.
