§
*The FT82011 and FR82011 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 FT82011MSTR-1, for example, is CT82011MSTR-1.
• For models with higher optical power budgets, contact the factory.
