* The FT82041 and FR82041 modules are classified by the FDA as Class 1 laser products. For 850 nm, the Class 1 laser limit is <0.78 mW. For 1310 nm, the Class 1 laser limit is <15.6 mW. For 1550 nm, the Class 1 laser limit is <10.0 mW.

When using 50/125 μm multimode fiber, subtract 3 dB from the optical power budget.

Maximum transmission distance is limited by fiber bandwidth.

§ Maximum transmission distance is based on attenuation of 0.5 dB/km plus a 5 dB buffer for connector and splice losses.

NOTES:

Single-mode FC connector is available upon request. Contact the factory for additional information.

For conformal coated models, replace the first letter F in the model number with the letter C. The conformal coated version of FT82041MSTR-1, for example, is CT82041MSTR-1.

For models with higher optical power budgets, contact the factory.
