Isn't Token Ring pretty much dead now? Back in the 90s it provided better performance than Ethernet, as there were no collisions and there was also the move to 16 Mb TR. But when switches and then 100 Mb Ethernet became popular, Token Ring was left in the dust.I believe it's used in bidirectional fiber-optic communications. To what extent, I'm not sure and to be honest I just looked that up.
Are you referring to FDDI? If so, that's also obsolete. I have worked with fibre and when a single fibre is used, different wavelengths are used for each direction.
