Notes:
1. SFF transceivers may be water washed. However, the process must be followed by a baking step at
80°C for one hour, to ensure the drying of any water which may be trapped inside then shells of the
modules.
VII.
Regulatory Compliance
Finisar transceivers are Class 1 Laser Products and comply with US FDA regulations.
These products are certified by TÜV and CSA to meet the Class 1 eye safety
requirements of EN (IEC) 60825 and the electrical safety requirements of
EN (IEC) 60950. Copies of certificates are available at Finisar Corporation upon request.
