Frequently Asked Questions

What fiber cable works best with the 140NRP31200?

• The 140NRP31200 supports multi mode fiber with 50/125 µm or 62.5/125 µm core sizes. Use 50/125 µm for distances up to 2000 meters. Use 62.5/125 µm for distances up to 3000 meters.

How do I interpret the attenuation specifications?

• Attenuation indicates acceptable signal loss through the fiber. For 50/125 µm cable the range is -23.5 to -14 dB. For 62.5/125 µm cable the range is -20 to -14 dB. Staying within these ranges ensures reliable communication.

Can this module operate outdoors?

• The 140NRP31200 carries FM Class 1 Division 2 certification for hazardous locations. However the operating temperature range is 0 to 60 °C. Protect the module from direct exposure to weather extremes.

What does the -45 dBm detected silence value mean?

• Detected silence at -45 dBm tells the receiver when the optical signal drops below usable levels. This helps the system recognize link failures and manage network redundancy effectively.

Does the 140NRP31200 require software configuration?

• No software configuration is necessary. The 140NRP31200 operates as a physical layer media converter. Simply connect the fiber and copper cables correctly and the module works immediately.

What do the LED indicators tell me during operation?

• Green RDY means the module powers up correctly. Red ERR signals an internal fault. STS1 and STS2 indicate active fiber links. FX1 ACT and FX2 ACT flash during data transmission on each channel.
