I would like to use a fiber connection to send data between two nodes. The nodes would typically have a 8 or 32 bit micro controller. I need data rate of 2 Mbps or higher and distance is about 100 meters. What are some cost effective ways of achieving this? Can full duplex communication be achieved with single fiber as is the case with fiber from various ISPs?

    \$\begingroup\$ You probably want to look at "industrial fiber optics" possibly using plastic optical fiber (POF) although 100 m might be a bit long for POF. \$\endgroup\$ – The Photon Feb 2 '18 at 15:51
  • \$\begingroup\$ Happen to be at the digikey site POF 250m = $411 with 200dB/KM I have no idea how easy it is to splice POF yourself... \$\endgroup\$ – Oldfart Feb 2 '18 at 15:56

    \$\begingroup\$ I know every little about this but my gut feeling is that electrical transport might be simpler, cheaper and just as reliable. Why not ask: what electrical protocol/system lets me transport 2Mbs over 100m. \$\endgroup\$ – Oldfart Feb 2 '18 at 16:34
  • \$\begingroup\$ Are you worried that cable comms cannot easily hack 100 metres at that snail rate of 2 Mbps? XY problem? \$\endgroup\$ – Andy aka Feb 2 '18 at 16:50
