Hvad er 10GBE?

10-gigabit Ethernet (10GBE) er den hurtigste Ethernet-standard for fast kablede lokalnetværk (LANS) siden 2005. Det kroner det seneste i en lang liste over Ethernet-teknologier, der er standardiseret af Institute of Electrical and Electronics Engineers (IEEE) i deres specificering 802.3x. The 10GbE network operates at a rate of 10 gigabits per second (gbps), or ten times faster than standard GbE. Ethernet cabling is used to connect computers to hard-wired networks used in businesses, on campuses, and in homes. I årenes løb har teknologien til transmission af digitale signaler på tværs af Ethernet -kabling, inklusive selve kablingen, udviklet sig for at muliggøre hurtigere dataoverførselshastigheder.

Ethernet -standarder henvises ofte til i forkortet form. Hastigheden er indikeret først, efterfulgt af ordet "base" for baseband , og til sidst en 2-cifret forkortelse for den anvendte kabelteknologi. When referring to a level of Ethernet without specifying the cable type, a simple “X” is usedto be inclusive. At a glance, this abbreviation reveals which type of Ethernet network is being referred to. For example:

• 10Base-X – Standard Ethernet at 10 megabits per second (mbps)
• 100Base-X – FastEthernet at 100 mbps
• 1000Base-X – Gigabit Ethernet at 1,000 mbps, or 1-gigabit per second (gbps), also known as GbE
• 10GBase-X – 10-Gigabit Ethernet at 10 gbps, also known as XGbE

10GbE is ten times faster than GbE and has many competing standards that will likely shake down to a few over time. Most types of 10GbE use single or multi-mode optical fiber cabling. Single mode optical cable is used for 10GBase-LR (long range) and 10GBase-ER (extended range). Multi-mode optical fiber cable is used for 10GBase-SR (short range), 10GBase-LX4, and 10GBase-LXM. Wide area networks (WANs) have their own varietiess of 10GbE: 10GBase-SW, 10GBASE-LW og 10GBASE-EW.

For at køre korte afstande med 10GBE er der den billigere 10GBASE-CX4, et kobberalternativ. Dette bruges ofte til broer, såsom ledningsrouter til at skifte. En traditionel type 10GBE, der bruger snoede par kabler, skal standardiseres af IEEE i 2006, som 10GBASE-T . Det snoede par kabling, der bruges til 10GBE, skal opfylde tekniske specifikationer, der kræves af kategori 6A kabel, eller "CAT-6A" kort.
