RE: [expert] CAT-5 10BaseT cable max length
Not really, given wasted bandwidth due to collisions and other issues. The best case scenario (only two machines for instance) yields a statisticall 70% utilization or 7 megabits or .875 MegaBytes. Usually is less than that, be happy with 60%. By the way this applies to any collision detection ethernet protocol so the same with 10BaseT and 100BaseT although if you are switching at the hub you are going to be a bit more efficient. > -Original Message- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, November 10, 1999 10:36 PM > To: [EMAIL PROTECTED] > Subject: Re: [expert] CAT-5 10BaseT cable max length > > > > > 10 megabits that's the reason its called 10base-X > > > > > Ian Douglas <[EMAIL PROTECTED]> on 11/11/99 04:01:49 AM > > Please respond to [EMAIL PROTECTED] > > To: [EMAIL PROTECTED] > cc: (bcc: Hamka B Hj Suleiman/SKO/PCSB/Petronas) > Subject: Re: [expert] CAT-5 10BaseT cable max length > > > > > Speaking of 10base2 ... what is the maximum bandwidth on > coax?

I believe the maximum theoretical > length is like 1200 feet or something. Well, the official spec in the RFC is 105 meters for coax, but the STP will go farther. Intense planning effort is necessary to protect the cable ends from g-force in a longitudinal direction. A hub on top of a bookshelf with its interconnecting STP Cat-5 cabling in the drop ceiling above it was moved by overzealous renovators resulting in a fall that jerked the cable ends. The result? Short. Hub replaced for excessive ringing. Ethernet card replaced for excessive ringing, and three hours of my time figuring out the fault and replacing cable in a ceiling. I have hubs linked by a 10base2 backbone and it works acceptably. the runs are 8 to 15 meters on the cat 5 and 15 meters between hubs using coax for a total of 45 meters of coax. Civileme
Re: [expert] CAT-5 10BaseT cable max length
Total length for a single run of cat5 is 100m. Of course you have some room to play in this number if you are not looking for an actual cat5 certification. Long runs parallel to flourescent lights may see attenuation prior to 100m while long runs through warehouses away from electrical interference may go 110 - 120m safely.

IF you are at 10 Mbps use the 5-4-3 rule: No more that 5 segments between any two nodes, no more than 4 repeaters (hubs) and no more than 3 segments can have end stations on them. For 10-baseT that last rule is superfluous. -- Stephen Carville [EMAIL PROTECTED] There are two kinds of people: those who do the work and those who take the credit.

RE: [expert] CAT-5 10BaseT cable max length
A lot will depend on the data rate and the device on the cable, but I'd say 100-200 meters on CAT5 UTP. You might get away with a little longer on 10base - but if you're running 100, Gig, or ATM you might see "issues". Another consideration is proximity to power sources if you run UTP - AC current = bad. I have also seen data errors on cabling that had been bent too much repeatedly! Lemme tell you how fun that was to trace down carrier does not always mean transmission.

Re: [expert] CAT-5 10BaseT cable max length
Lee, 10BaseT cable lengths for a ethernet network should not exceed 100 meters. (That is the rule we use and the standard for 10BaseT) See Ya Darryl Lee Wilson wrote: > Anyone know how long I can got with Cat-5 10BaseT cabling and not have > attenuation errors or lost data, etc?
Re: [expert] CAT-5 10BaseT cable max length
Lee, I think it is 35 feet...I do not remember, but to be on the safe side I would place a hub or router after 30 feet... again I do not remember the exact length, it also depends on the quality of the cable as well.
