Fast Ethernet vs Gigabit Ethernet | Difference between Fast Ethernet and Gigabit Ethernet

Fast Ethernet and gigabit ethernet are two types of ethernet that are extremely fast. The following are the key difference between fast ethernet and gigabit ethernet.

What is Fast Ethernet?

Fast Ethernet is also known as 802u. it was developed to compete with the LAN protocol FDDI. As a successor to 10 base T ethernet, it is entirely based on 10 base T ethernet. It was popular due to its ease of implementation, management, and upkeep. Backward compatibility is an advantage of fast ethernet. It is ten times faster than its predecessor and can provide data speeds of up to 100 Mbps.

What is Gigabit Ethernet?

Gigabit Ethernet was designed to provide higher transmission rates of up to 1 Gbps. The initial plan was to create technology that could be used with existing networking equipment. It is built on top of ethernet protocols such as CSMA/CD. It like fast ethernet support both full-duplex and half-duplex modes.

  • Fast ethernet is the successor of 10 base T ethernet, while the gigabit ethernet is the successor of fast ethernet.
  • Fast ethernet speed is up to 100 Mbps, while the gigabit ethernet speed is up to 1 Gbps.
  • Fast ethernet is simple to configure, while the gigabit ethernet is quite complex to configure.
  • Fast ethernet generates more delay, gigabit ethernet generates less delay than fast ethernet.
  • The fast ethernet coverage limit is up to 10KM while the gigabit ethernet coverage limit is up to 70KM.
  • Fast ethernet round trip delay is 100 to 500-bit times, while the gigabit ethernet round trip delay is 4000-bit times.
