We need about 700' of cat 3 outside premise cable to connect buildings on either side of a public road. Whoever installed the existing cable used indoor type cable which is now rotting in the pipe. I've priced it at about $1,200 which is mighty expensive for us. Do any of you on this forum in the San Francisco Bay area happen to have a spool lying around? I work for a 4 year non-profit college (accredited by WASC).

Check with businesses in your area for ones who might do educational contributions. Check with the Chamber of Commerce for recommendations on businesses to approach.
I wouldn't be too hard on the original installer. I have an almost identical situation to yours. The original cable and pipe was laid because the cost of an off premise phone cabinet and T1 link to a bldg. 1300' away for 18 mo. and the cost of laying the cable was a wash. Additionally at the end of the 18 no. we would have been stuck with phone equipment we didn't need. The cable was intended to be a throwaway. Problem is, that was 8 years ago.
What seems like a good decision can certainly look boneheaded later, but sometimes you don't know how much the situation has changed from when the decision was made.

Hey.
I'd like to add something to this.
As I understand it, copper cable should not be run to link buildings with separate power inlets because the buildings will have different earthing levels. The hazard as I understand it is that one building can be earthed into the other via your data flex. Therefore fibre should be run.
Is this wrong or can someone clarify the point, a little more technically?

The indoor cable we have is, of course, not shielded. :-(
I've been punching the unused pairs to ground at both ends. Seems to help with noise and stray currents.
