Connector Fibre type Wave length Typical max.
length
1)
Permitted path attenuation
2)
LC MM 62.5/125 or 50/125 μm 1300 nm 2 km <8 dB
LC
SM 9/125 μm
3)
1300 nm 20 km <8 dB
1) Maximum length depends on the cable attenuation and quality, the amount of splices and connectors in the path.
2) Maximum allowed attenuation caused by connectors and cable altogether
3) Use single-mode fiber with recommended minimum length of 3 m to connect RED615 to the pilot wire modem RPW600.
