FAQs

Q: What is the difference between IR-1 and LR-1 optics?
A: IR-1 (I-16.1) targets intermediate reaches around 15 km at 1310 nm, while LR-1 (L-16.1) supports longer spans around 40 km at 1310 nm.

Q: Does this optic require dispersion compensation?
A: For typical IR-1 distances (up to ~15 km at 1310 nm), dispersion compensation is not required.

Q: Is this suitable for outdoor cabinets or industrial sites?
A: Yes, the industrial-temperature rating supports deployment in extended environmental conditions.

Q: Can I mix IR-1 optics with LR-1 on the far end?
A: Both ends must meet optical budget and wavelength/standard alignment. Mixing can work if the link budget and standards are compatible.
