*The FX82052 module is classified by the FDA as a Class 1 laser product. For 1310 nm, the Class 1
laser limit is <15.6 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 connectors are 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 FX82052MSTR-4, for example, is CX82052MSTR-4.
• For models with higher optical power budgets, contact the factory.
