We have an extensive fiber to the desk network. The pros are that it allowed us to centralize equipment much farther away from the clients than the 100m distance limitation of twisted pair. This allowed for better port utilization, better environmentals (power and cooling in one place rather than lots of closets) The current plant we're on has supported us from 10BaseFL, 100BaseFX, ATM155, and will continue to support us through 1000BaseX (though we might run into some distance limitations on some of our stations). So, the plant has last much longer than a copper plant would have. Cons: The electronics are more expensive: fiber switchports will cost mor and you'll need media converters or fiber NICs, the fiber patch cords are more expensive. Connectors: There has been one copper connector for twisted pair ethernet, while we have several for fiber No speed negotiation: we do have some devices that are 10Base-T only or 100Base-T only, so that presents a challenge (different client equipment to allow for rate adaptation. New problems that are arising: No realistic PoE option: we have a growing demand for network powered devices (APs and phones). There are power injecting media converters, but they are more expensive. What specifically is leading you to FTTD? -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkr8J7AACgkQQr/gMVyFYyRmFwCgiZ1XuiekECwHV8j/dIotw9e6 oJoAn19+LKKiZ8lfp0HpKZZabvDw7KEI =6iNY -----END PGP SIGNATURE----- _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
