The SFP replaced the larger gigabit interface converter (GBIC) in most applications, and has been referred to as a Mini-GBIC by some vendors. [3] SFP transceivers exist supporting synchronous optical networking (SONET), Gigabit Ethernet, Fibre Channel, PON, and other communications standards.
Router with two dozen 10 Gigabit Ethernet ports and three types of physical-layer module. 10 Gigabit Ethernet (abbreviated 10GE, 10GbE, or 10 GigE) is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. It was first defined by the IEEE 802.3ae-2002 standard.
The Ethernet physical layer has evolved over its existence starting in 1980 and encompasses multiple physical media interfaces and several orders of magnitude of speed from 1 Mbit/s to 800 Gbit/s. The physical medium ranges from bulky coaxial cable to twisted pair and optical fiber with a standardized reach of up to 80 km.
Switching media converters can connect different speed network segments. For example, existing half-duplex hubs can be connected to 100BASE-TX Fast Ethernet network segments over 100BASE-FX fiber. When expanding the reach of the LAN to span multiple locations, media converters are useful in connecting multiple LANs to form one large campus area ...
Newer routers, hubs and switches (including some 10/100, and all 1-gigabit or 10-gigabit devices in practice) use auto MDI-X for 10/100 Mbit connections to automatically switch to the proper configuration once a cable is connected. Gigabit and faster Ethernet links over twisted pair cable use all four cable pairs for simultaneous transmission ...
Supermicro AOC-SGP-I2 dual-port Gigabit Ethernet NIC, a PCI Express ×4 card. 1000BASE-T (also known as IEEE 802.3ab) is a standard for Gigabit Ethernet over twisted-pair wiring. Each 1000BASE-T network segment is recommended to be a maximum length of 100 meters (330 feet), [5] [a] and must use Category 5 cable or better (including Cat 5e and ...
