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

IIIb
1550 nm
1310 nm
IV
1550 nm
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 whereas classes IIa, II and
IIIa apply only to those lasers operating within the visible wavelength
range (400-700 nm). Lucent Technologies 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.
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.

Notes:
1 Class 3R only exists if the maximum power is within five times the
Accessible Emission Limit (AEL) of Class 1.
