FAQs

Q: Do I need the same optic on both ends?
A: Yes. Use matching 1G 1310 nm long-reach LC optics on both ends to ensure link stability.

Q: What fiber is recommended?
A: Use low-loss OS2 single-mode fiber and low-loss LC connectors for long distances.

Q: Will this work with a ZX (1550 nm) optic at the other end?
A: No. Both ends must use compatible wavelength and standard (e.g., 1310 nm EX to 1310 nm EX/LH).

Q: Is attenuation control needed for short links?
A: On very short SMF runs, optical attenuators may be required if receiver overload occurs. Check device specs.
