Right now you need GBICs, a splicing cassette, and a splicer 
(a 10 k$ device). The future looks very bright for polymer fiber,
which can be processed with a simple sharp knife (100 MBit/s
Ethernet kits + converters are reasonably cheap, 1 GBit/s 
is being developed -- 10 GBit/s might be rather challenging,
unless there's photonic crystal technology).
