100 base on bnc cable

hello who ever is reading this.... i ahve been looking around for a network card both a RJ45 on it and a BNC socket which runs at 100bps... coudl some one shed some light on me and tell me such a think as 100 base networkd cards with a BNC port...

thank you
 
3COM had/has some NICs with both, but I'm pretty sure the BNC connector was 10Meg only (10BASE-2). I'm not aware of any 100 meg Ethernet-over-coax NICs.

Good Luck in your search.

Although BNC cable is certainly capable of data rates higher then 10Mb, I've never seen a card that supported it.

Bandwidth limitations? Um...the scrappiest, crummiest coax can handle bandwidth well beyond anything UTP can do. UTP was adopted because (at least at the time) it was less expensive, and the concept of structured cabling adapted well to that media. Plus in the meantime, people have become so coax-phobic it'd never sell.

You wanna hear ugly? Try Gigabit/Ten Gig over TWINAX...it's been / being considered....makes ya crimge don't it?

Coax (from an electrical standpoint) is far superior to UTP. 100 Meg on coax is trivial. The stuff you use for your TV or satellite feed goes to over 900Meg. Implementing it for networking as a structured cabling component is the bad part...hard to find coax telephones.


FWIW
