Can a single optic fibre installation transmit multiple connections,

For example, There are two networks, each network sends and receives data to or from. My question is can both the two networks be transmitted through a wired optic fibre?

Please correct me if am wrong


I think you don't really understand what you are asking. A fiber is a layer-1 link and it will transmit network traffic. It doesn't matter the what the source or destination addresses are on the layer-3 packets; the fiber neither knows or cares what network traffic it carries.

What matters is that you use routers. Routers route traffic between networks. You terminate the fiber with a router on each end, and use a routing protocol between the routers to share routes between the routers.

  • Oh please correct me if am wrong, so that means any amount of network traffic can be transmitted as long as the fiber can handle it? On the end of the fiber can there be multiple routers? or it's only one router that should route the traffic to corresponding networks Nov 20 '16 at 7:57
  • A single fiber link (usually two fibers: one for transmit, and one for receive) will have one router on each end, but a router can have links to other routers, so that you can have unlimited networks on each end. That is how networks, including the Internet works.

  • Crystal clear! your a genius Sir. Nov 20 '16 at 21:41
  • I'd add that there are ways to share fibre which are not routing. Foreign wavelengths in Wave Division Multiplexing are extensively used by telcos and large ISPs wishing to share fibre optical links.
