The document that I send did not attached so It should be
The distance is measured between the Catalyst 2900 LRE XL switch and the
Cisco 575 LRE CPE. In the throughput measurement it is assumed the the bit
rate is full duplex channel. In ideal conditions, the performances are:
15 Mbps symmetric (30 Mbps aggregated) up to 3500 feet
10 Mbps symmetric (20 Mbps aggregated) up to 4000 feet
5 Mbps symetric (10 Mbps aggregated) up to 5000 feet

Subject: Long Reach Ethernet
Hello groupstudy,
Does anyone know if there is a minimum distance
physical
limitation of long reach ethernet.
The only thing I find on CCO is 3500 feet and above. At our network, we are
running it on a telephone wire
that is less than 200 feet and I was wondering whether this could actually
be
hindering performance. You
don't want to know the reasons of why this is being done, for it is beyond
the
limits of rational thought. I
already had a TAC engineer check and they couldn't find anything [ yet ]
Any comments welcome.
