These devices employ a variety of transmission technologies and physical media wireless, copper wire, fiber optic cable, coaxial cable . The extender forwards traffic between LAN s transparent to higher network layer Communications protocol protocols over distances that far exceed the limitations of standard Ethernet. Options Extenders that use copper wire include 2 and 4 wire variants using unconditioned copper wiring to extend a LAN s. Network extenders use various methods line encodings , such as TC PAM , 2B1Q or Discrete multitone modulation DMT , to transmit information. While transmitting over copper wire does not allow for the speeds that fiber optic transmission does, it allows the use of existing voice grade copper or CCTV coaxial cable wiring. Copper based Ethernet extenders must be used on unconditioned wire without load coil s , such as unused twisted pairs and alarm circuit s. Connecting a private LAN between buildings or more distant locations is a challenge. Wi Fi requires a clear line of sight, special antennas, and is subject to weather. If the buildings are within 100m, a normal Ethernet cable segment can be used, with due consideration of potential grounding problems between the locations.

unreferenced date December 2006 Fibre Channel Switched fabric , switching fabric , or just fabric , is a Computer network network Network topology topology where network nodes connect with each other via one or more network switch es particularly via crossbar switch es, hence the name . The term is popular in telecommunication , Fibre Channel storage area network s and other high speed networks, including InfiniBand . The term is in contrast to a broadcast medium, such as early forms of Ethernet . Switched fabrics can offer better total throughput than broadcast networks, because traffic is spread across multiple physical links. Similarly, some modern computers use a switched fabric, such as PCI Express , HyperTransport , or Intel QuickPath Interconnect QuickPath , instead of a Bus computing bus . Again, the advantage of the switched fabric is performance. Switched fabric in Fibre Channel Image Switched fabric.svg thumb 320px right Example topology of a Fibre Channel switched fabric network Image Dual fabric.gif thumb 320px right A storage area network built with two separate switched fabrics red and blue to increase reliability. In the Fibre Channel switched fabric topology called FC SW , devices are connected to each other through one or more Fibre Channel switch es. This topology allows the connection of up to the theoretical maximum of 16 million devices, limited only by the available address space 2 sup 24 sup . Multiple switches in a fabric usually form a mesh network , with devices being on the edges leaves of the mesh. While this topology has the best scalability properties of the three FC topologies, it is also the most expensive, the only one requiring a costly fibre channel switch . Visibility among nodes in a fabric is typically controlled with Fibre Channel zoning zoning . Most Fibre Channel network designs employ two separate fabrics for redundancy engineering redundancy .
