Spectrum measured by CCS175.
Important Notes:
1. The maximum ratings mean the limitation over which the laser should not be operated even instant
time.
2. Do not clean the fiber connector when the diode is in operation. The laser should be off when
plugging or un-plugging the connector.
3. To protect the laser diode from damage due to static electricity (ESD), please follow proper ESD
handling precautions.
4. Do not pull or fold the fiber. The fiber is very fragile and easily broken. Avoid handling the fiber by
the rubber “boots” of the black housing and connector ends of the pigtail.
5. To ensure safe operation use only with a suitable power source that complies with the pertinent
requirements for laser systems as specified in IEC-60825-1 “Safety of Laser Products.”
6. Due to the nature of Fabry-Perot laser diodes, the spectrum output will be affected by several factors
such as current, temperature, and feedback to the laser. Thus, although the center wavelength will be
within the specified tolerance, please note that the peak will vary.
