3. Class 3B requires strict engineering controls.
4. Classification is under single fault conditions.
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
I 1310 nm
1550 nm
IIIb 1310 nm
1550 nm
IV 1310 nm
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. 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 standard.
Laser class Wavelength
1 1310 nm
1550 nm
3A 1310 nm
