Ethernet IP networks are prolific within both the business and home environments.
Fibre Technologies already supplies some of the world's most well known service providers with demarcation products for 10Mb, 100Mb, 1Gb and 10Gb Ethernet,
to use on the end of their fibres, so they can in turn offer their end customers an Ethernet service.
These LAN extension products can offer either a copper or a fibre optic interface, depending on the speed that is needed and where in the network it is required. They can also be managed by the end customer, the service provider or even by a support and maintenance company, to enable performance monitoring, remote testing and rate limiting.
Layer 2 switches available with multiple copper or fibre ports (or a combination of both), are another network performance monitoring tool.
Similar products are available for Fibre Channel protocols that currently support 1, 2, 4, 8 and 10GB and in the near future FCoE.
