[comp.protocols.tcp-ip] Standard cable lengths

greg@duke.cs.unlv.edu (Greg Wohletz) (12/16/89)

To quote from some cabletron documentation:

	When making up networks requiring shorter cable run, Ethernet
standard length 23.4m, 70.2m, and 117 meter cable sections should be
used.  These cable sections may be connected together to form a cable
segment by using a barrel connector.  Use of non-standard cable
lengths may result in impedance mismatches causing reflections to
occur.  These reflections may cause data errors.


My question is how critical is this?  I have some cable runs that will
probably be around 100 meters, should I be sure they are 117 meters?
