*The FT8308 transmitter and the FR8308 receiver 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 FT8308MSTR, for example, is CT8308MSTR.
• For models with higher optical power budgets, contact the factory.
