-  Two mono-mode fibres are required per network section.
 -  The fibers must be connected directly without interruption (e.g. no connection via multiplexers permitted)
 -  Fiber type E9/125 μm
 -  max. permitted attenuation of 17 dB corresponds to a length of approx. 20 km or
 -  Fiber type E10/125 μm
 -  max. permitted attenuation of 17 dB corresponds to a length of approx. 20 km
 -  Up to 16 optical fiber paths per essernet network are possible with a transmission rate of 62.5 kBd
 -  Up to 31 optical fiber paths per essernet network are possible with a transmission rate of 500 kBd
