The fiber cable itself is finicky and ideally you would buy it from a<br>
supplier who will cut it to the right length and put the right<br>
connectors on it for you (because doing this in the field requires<br>
custom equipment, trained personnel, and is slightly hazardous with<br>
tiny bits of glass fiber that can get under your skin). Fiber cables<br>
can't be bent as much as cat5 cables (or the glass fibers inside<br>
break) so you have to take some care installing them. Unfortunately<br>
there are no standards for fiber connectors, or rather there are<br>
dozens, so you'd have to pick one connector type (e.g. "LC"<br>
connectors) and get the cable and the SFP that have those connectors.<br>
There are half a dozen 1000Base-something standards for fiber<br>
ethernet, too, for different kinds of fiber cables and different<br>
distances, so you have to specify which standard your SFP's will use.<br>
You may need a pair of cheap attenuators too, if your fiber run is<br>
short (to reduce the intensity of the light in the fiber). Compared<br>
to just getting cat5e or cat6 cables and plugging them into a cheap<br>
and standard switch, fiber is much more complicated and expensive.<br></blockquote><div><br></div><div>It depends on the port count and how managed it is.<br><br>Netgear has at least one semi-fancy switch (8 port PoE+2 port SFP) for $150.

they burn (e.g. when the building catches fire), they don't release<br>
