Looking for advice: ST FDDI fiber plants but trying to go 10G.

I'd like to go 10g from my MDFs to my IDFs. Several of my sites are FDDI only with ST connectors. No single mode.

My hardware is Cisco across the board. The SFP-10G-LRM can do this but requires a mode conditioning cable over FDDI. Cisco offers the CAB-MCP-LC, which is a 1m LC-SC mode conditioning cable. In fact all of Cisco's options are SC related.

All of the Cisco options are 1 meter long. In some cases my switches are near the bottom of the racks while the fiber is at the bottom or vice-versa.

This is a headache. Here are my options as I see them:

1) Find a different mode conditioning cable. I am not married to the idea of using Cisco branded mode conditioning cables, but I can't quite seem to find others. If you can suggest one I'll check it out.

So other than getting different mode conditioning cables, here are the other options I think I have:

2) Build a breakout panel of SC-SC adapters - Populate that with SC-ST patch cables back to my fiber plant. I can adjust the length so that it is is in range of my distribution. Mostly will look like crap, but gets the job done. Adds another point of failure.

3) Swap adapter panels with ST-SC adapters - Prettiest option as it moves the panels to SC yet doesn't make me re-terminate hundreds of connections. However there are at least three different brands and models of patch panels, all over 10 years old that I will have to find model#s and adapter plates. I can't seem to find a quantity discount for the SC-ST adapters.

4) Re-terminate all of our patch panels to SC and re-box all fiber - Since the plates used in the various racks across the buildings are really old, simply buying the right inserts isn't going to work. Will look better but doesn't fix the length issues, so I will have to move my distribution switch.

5) Replace my cable plant - Someone will suggest it, and they aren't wrong. This is not really an option since I am sure I would get shot down budget wise. If I could do it, I'd go SC and SM. Or MTP and SM.

Any other ideas out there or advice on this?
