FDA/CDRH laser classification
The following table provides an overview of laser classes for wavelengths of 1310 nm
and 1550 nm in accordance with the FDA/CDRH regulations.
Laser class Wavelength Max. output power of laser radiation
I 1310 nm 1.53 mW +1.85 dBm
1550 nm 8.52 mW +9.3 dBm
IIIb 1310 nm 500 mW +27 dBm
1550 nm 500 mW +27 dBm
IV 1310 nm > 500 mW > +27 dBm
1550 nm > 500 mW > +27 dBm
Explanatory note: In the United States, lasers and laser systems are assigned to one of
the following classes: Roman numerals I, IIa, II, IIIa, IIIb, and IV. Classes I, IIIb, and
IV apply to lasers of all wavelengths. Classes IIa, II, and IIIa apply only to those lasers
operating within the visible wavelength range (400-700 nm). Alcatel-Lucent laser
products typically operate in the infrared wavelength range (greater than 700 nm) and,
therefore, are primarily in the Class I or Class IIIb classifications.
IEC laser classification
The following table provides an overview of laser classes for wavelengths of 1310 nm
and 1550 nm in accordance with the IEC 60825-1 Ed. 1.2 (2001) standard. The precise
power limits depend on the mode field diameter and the numerical aperture (NA) of
the laser source.
Laser class Wavelength Max. output power of laser radiation
1 1310 nm 15.6 mW +11.93 dBm
1550 nm 10 mW +10 dBm
1M 1310 nm 50.84 mW +17.06 dBm
1550 nm 121.20 mW +20.84 dBm
3R 1310 nm 86 mW +18.92 dBm
