A quick search of the IEEE 802.3 spec didn't turn up any matches for 1 m as being the minimum length for 10BaseT (nor even 10Base2). There is a reference in the document however in Section 14 - "Twisted Pair Medium Attachment Unit (MAU) and baseband medium, type 10BaseT" has a clause that indicates that the MAU has a characteristic that it provides for operating over "0 m to at least 100 m (328 ft.) of twisted pair without the use of a repeater". Now I might be interpreting this wrong, but I'd say that 10BaseT has no minimum length... -- Leigh Anne -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Murphy, George Sent: Saturday, July 21, 2001 11:00 PM To: [EMAIL PROTECTED] Subject: RE: Ethernet Trivia mostly, Need an EE's answer probably.

[7:13199] We all hear about max cable lengths for Ethernet. But is there a minimum? If the TX pair of one side connects to the RX pair of the other, then collisions, if any, happen at the ingress of the hub or switch in the buffer, or on the buffer of the nic if just using a really short cross over, is this right? I've looked and looked, and haven't been able to get an answer that says "the minimun length of a Category 5 100Base connection is x feet" even the spec seems to be silent on it. What am I missing in my knowledge of physics and electronics? p.s. My foot long patches between hosts and a hub don't seem to cause errors. I'll stick a sniffer in this week and see if I see any. I'm manufacturing these 3 inch patch cables for my test.
