* 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.
