Usage Guidelines & Best Practices
Fiber Choice: Works only with OS2 single-mode fiber. Multimode fiber is not compatible with this 1310nm CWDM4 module.
Optical Attenuator Required for Short Links: For testing or short-distance connections (<15km), connect a 15dB–20dB optical attenuator to the RX port to prevent damaging the receiver.(<25km,connect 10-15dB optical attenuator)
Cleanliness & Dust: Keep dust caps on whenever unattached. Clean fiber end-faces with a optical cleaning pen before insertion; dust causes over 80% of optical link failures.
Installation Specification: Hot-swap supported. Follow ESD anti-static procedures and keep LC connectors clean for stable links.
Operating Environment: 0°C–70°C commercial temperature range. Ensure cabinet ventilation to avoid optical power attenuation from overheating.
