[c-nsp] Fiber

[madunix]

am just trying to take advantage of using light technologies in LAN
for our new building, due to long distance between the offices over
90m, i know fiber is fast expensive and copper gigabit still far
cheaper, and fiber to desktop isn't required for a majority of
applications.

Thanks

Also Desktop fiber aggregation is much more expensive in terms of line cards, diversity of switch choices, lack of desktop NICs. Usually I hear FTTD being done to "future proof" the wiring. Most of the times the fiber never ends up being used. Cat6a is backwards compatible with 5e, so if you are doing a new wiring plant, that's enough "future proof" for the next reasonable term.
