Re: Wiring new home - use that extra SM fiber after all?
I would say no. For little distances like that, you would want multi-mode, not single-mode. I'm looking at using fiber too (since I have a crap-ton of extra fiber around, and the gbics for the switches), but using multi-mode. Also, if you do use single-mode equipment, you'll probably either need a lot of attenuators, or bend the fiber to reduce the light strength yourself. If the light level is too high going into the receive on a device, you can fry the optics, reducing the lifespan of the device. | |

I think that would be an issue unless he attenuated properly for the media converters, which shouldn't be too hard to do. MM isn't a "must" for short distances, there are plenty of short-reach, SM cards/GBICs/SFPs in use across a wide variety of equipment. | |

Yep, it's not rare to link two SONET nodes in the same bay with only few feet of optical cable
