> I need to know your opinion about fiber to desk i.e. pros and cons..

If one needs fiber for distance, electrical isolation, 
limited space/cooling for access switches, etc., one
may want to look at various FTTx technologies (xPON and
friends) which can provide fiber to "near" the desk with a
relatively low cost drop to copper (the ONT) at the desk.
Note that FTTx is (mostly) a residential subscriber type
of solution (more bandwidth *to* the desk than from it),
and that may not meet the needs of servers or "power
users" (that are really more like servers).  As with all
else, your particular situation will vary.

A presentation by Sandia at the Internet2/ESCC Joint
Techs meeting in Indiana in June of 2009 discussed their
particular FTTx plans (and may provide some thoughts):
