Does anyone know of a product to run token ring over fiber optic cable without using a fiber optic MAU? We have a router located in the basement of a large building and fiber optic cable running vertically throughout. To connect to an Ethernet we use fiber adapters from Fibermux to extend the 50 meter drop cable length to connect a thick Ethernet on the 11th floor to the router in the basement. We have succesfully connected 24 Ethernets in this building using this method. A token ring using an IBM MAU exists on one of the floors. Is there any way to do the same thing with Token R ing? -- ___________ jim brunetti brunetti@alw.nih.gov

Are you planning to put TR's on each floor? If so, you may want to consider putting a backbone ring vertically with access centers for separate rings on each floor (perhaps one ring could span a couple of floors). There are many considerations in designing this set up such as wiring type, ring speed, number of stations etc. We do have some TR products available(including those that have fiber ring ports ant twisted pair station ports on the same board) and would be happy to assist you.
