Please log in for more thread options If only one off, I'd be temped to go with pre terminated cables. It's been a while, but when I used to buy fibre cables, I usually had them terminated by the supplier. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

The lowest-tech fiber you can still buy is an old 160MHz/km-bandwidth multimode 62.5/125 micron, which is going to support 2000 meters at 100Mbit/s, so 600' are not a problem at all. There are even older types available exclusively from eBay's surplus dealers, such as 100/140 micron multimode fiber. No matter how cheap, don't even think of getting these: no way to buy connectors anymore. Anything relatively recent would be for 125 micron outside diameter. The costs hugely depend on the type of jacket the cable is going to have, not so much the fiber itself. The OP did not specify the environment, but I think it would be wise to install an indoor-outdoor cable with at least 4 fibers (though only two will be utilized right away) or, better yet, 6. It would probably run you roughly 50 cents per foot. Plus installation. Expect to pay anywhere from $50 to $75 per connector if you hire a pro. Very small job, so per-item costs are going to be very high. > Also the URL for the economy model transceivers appropriate to convert

These guys are as "economy" as it gets to the best of my knowledge, but don't take my word for it - do a Google search: http://www.ramelectronics.net/html/fiber_hubs.html > What are the cost/distance/speed tradeoffs for 10Mb and faster, up to

At this point in time there is no price difference between 10 and 100Mbit/s (if you can still find 10, of course) Good luck! -- Dmitri Abaimov, RCDD http://www.cabling-design.com Cabling Forum, color codes, pinouts and other useful resources for premises cabling users and pros http://www.cabling-design.com/homecabling Residential Cabling Guide ------------------------------------- ##-----------------------------------------------## Article posted with Cabling-Design.com Newsgroup Archive http://www.cabling-design.com/forums no-spam read and post WWW interface to your favorite newsgroup - comp.dcom.cabling - 1309 messages and counting! ##-----------------------------------------------## | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

I need to pull cable from the second floor of a building through a (properly designed) chase, then through a (properly designed) underground conduit for about 400 feet, then through a chase into a second building. We currently have 10-Base-2 and want to up the speed. Your specific suggestions, and rough cost estimates, based upon the information I have provided would be most welcome.
