Controllable Fast Ethernet Switch

I'm trying to implement a system that would switch from an Optical Ethernet Link to an RF link during periods of heavy fog/rain.

The Optical Modem has an output 'A' that goes high when the signal is lost.

What I'm looking for is an off the shelf Fast Ethernet switch that could be used to switch an incoming 100baseT signal from the Optical to the RF modems given the value of A.

If someone has a better solution, that may be accepted as well.

Regards,

James K. Fegan

This may not be exactly what you are looking for, but here goes:

It may be possible that there are transceivers that will convert the RF and optical signals to fast ethernet over cat 5, in which case they can be hooked up to any off-the-shelf switch supporting spanning tree algorithms. The priority could be set to favor the optical link, but fail over to the RF link when needed.

Hope that helps,

My company built the transceiver, so we can't change that. I'm trying to find an off-the-shelf switch that can work with the design we have. Thanks for trying though.
