Fast Ethernet (FE) is a term of Ethernet in computing networking, which stands for carrying on the traffic at the speed of 100 Mbps. It came into the market in 1995 with the IEEE 802.3u standard and the original version was at the rate of 10 Mbps. Fast Ethernet makes use of 100BASE-T, 10BASE-T, 100BASE-TX and so on. 100BASE-T is the most common Fast Ethernet, whose cable’s segment length is limited to 100m. 100BASE-TX is the predominant form of Fast Ethernet, and each network segment can have a maximum cabling distance of 100m. Besides, Fast Ethernet has different features such as several PHY layers, and both full duplex and half duplex modes are supported by it.
Another type of Ethernet offers 1000Mbps in computing networking, therefore, got the name gigabit.
Gigabit Ethernet (GE) was released only a few years after Fast Ethernet coming about, but was not widely used until the internet demands increased around 2010. It uses a frame format of 803.2 and also runs on half duplex and full duplex modes. The maximum length of this system can be up to 70km, therefore most universities and companies use it. GE has different versions such as 1, 10, 40 and 100 gigabits. There are several typical varieties of Gigabit Ethernet, for example, 1000BASE-CX is an initial standard for Gigabit Ethernet connections with maximum distances of 25m, 1000BASE-KX is part of the IEEE 802.3ap standard for Ethernet operation over Electrical Backplanes and its specified distance is 1m, 1000BASE-SX is an optical fiber Gigabit Ethernet standard for operation over multi-mode fiber using a 770 to 860 nanometer, near infrared (NIR) light wavelength.
- The simplest difference between Fast Ethernet vs Gigabit Ethernet is their speed. Fast Ethernet runs at the maximum speed of 100 Mbps and Gigabit Ethernet offers up to 1 Gbps speed which is 10 times faster than Fast Ethernet.
- Round-trip delay of Fast Ethernet is 100-500 bit times. As against, Gigabit Ethernet has the delay of 4000-bit times.
- Configuration problems in Gigabit Ethernet are more complicated than Fast Ethernet. Sometimes Gigabit Ethernet needs high-compatibility fiber switch to work with, for instance, 10gbe switch.
- The distance covered by Fast Ethernet is at most 10 km. However, the Gigabit Ethernet has the limit of 70 km.
- Gigabit Ethernet is more expensive than Fast Ethernet. Upgrading of Fast Ethernet from Standard Ethernet is easy and cost-effective while upgrading of Gigabit Ethernet from Fast Ethernet is complex and expensive.
- Gigabit Ethernet requires specifically designed network devices that can support the standard 1000Mbps data rate like Gigabit Ethernet switch. Fast Ethernet requires no specific network devices.
