* The FT85011A transmitter and compatible receivers are classified by the FDA as Class 1 laser products.
† 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:
• For conformal coated models, replace the first letter F in the model number with the letter C. The conformal coated version of FT85011AMSTR, for example, is CT85011AMSTR.
• For models with higher optical power budgets, contact the factory.
