Introduction to Fast Ethernet

For years, Ethernet has proven itself inexpensive, fast and reliable local area network technology.  In 1972 Bob Metcalfe and D.R. Boggs developed Ethernet Technology and it was published in 1980 under the IEEE 802.3 set of specifications. Ethernet is a vendor-neutral computer networking standardized technology and major local area network standard.  Fast Ethernet is an Ethernet standard that supports data transfer rate at the speed of 100 Mbps against the standard Ethernet that supports 10 Mbps.  It is also referred as 100BaseT. 

 

The other relevant standards are 100 Mbps Twisted-Pair, Type 100Base-TX, 100 Mbps Fiber Optic, Type 100Base-FX, 100 Mbps Twisted-Pair, Type 100Base-T4, 1000BaseT (Baseband Ethernet over category 5 UTP Cable, 1000Base-X (generic name for the 1000 Mbps Ethernet System.  Fast Ethernet is ten times faster than the normal Ethernet 10-BaseT.  There are different cabling schemes that can be used with the fast Ethernet such as, two pair twisted pair cables, four pair twisted pair cable and fiber optic cables. It is a standard for LAN and based on the CSMA/CD local area network access method and it works with the twisted pair or fiber optic cables. 

 

Today many LAN cards support both Ethernet standards such as 10-BaseT and 100BaseT and these LAN cards are known as 10/100 Mbps. These LAN cards sense the data transfer speed and adjust it automatically.   The well known manufacturers of LAN cards are D-Link, RealTek, 3Com, LinkSys, Intel and BayNet.  There is another standard of the Ethernet known as Gigabyte Ethernet and it supports data transfer rate up to 1000 Mbps.

 

Ethernet works at the physical and data link layers of the OSI model and it supports IP protocol and other all the higher level protocols.  The most common standard of the Fast Ethernet is the 100Base-TX and it is supported by all the major Ethernet supported computer hardware.

The other relevant Ethernet technologies are Ethernet Switching, Ethernet Bridging and Ethernet VLANs.  In the 100Base-TX standard, the cable length is limited to100 meters this means that each network segment can have a maximum distance of 100 meters from the Hub/Switch.

Following list provides the detail about the other common standards of the Fast Ethernet.

100Base-TX

Operates over two pairs of category 5 Cable.

100Base-T4

Operates over four pair twisted pair cable.

100Base-T2

Operates over two copper pairs.
100Base-FX

It uses 100 NM infrared light wavelength over two strands of multi node fiber optic cables.

100Base-SX

It requires two strands of multi node fiber optic cable for data transmission.

100Base-BX

Single-mode fiber is used with the multiplexer.

Fast Ethernet provides the optimized performance to a local area network and cost-effective solutions to the businesses.  With the increased and simultaneous usage of the computer network servers and other resources, bottleneck is created so fast Ethernet with Gigabyte Ethernet as a backbone provides high performance and greater bandwidth.  Fast Ethernet switches can be upgraded to the Gigabyte Ethernet switches and the network servers can be directly connected to the Gigabyte switches that supports the data speed up to 100/1000 Mbps.
