10/100Mb - Denotes that this device can support both Ethernet (at a data transfer rate of 10Mpbs) and Fast Ethernet (at 100Mpbs).

10/100/1000T - Denotes that this device can support both Ethernet (at a data transfer rate of 10Mpbs) and Fast Ethernet (at 100Mpbs) and Gigabit Ethernet (at 1000Mpbs).

10/100TX - the same as 10/100Mb, the TX is an abbreviation of the standard for 100Mb Ethernet - 100Base-TX

100Base-BX10 - A standard of Fast Ethernet which is over a single strand of Single Mode fibre is capable of a distance of up to 40km. Uses 1310nm & 1550nm wavelengths, one to transmit, one to receive.

1000Base-BX10 - A standard of Gigabit Ethernet which is over a single strange of Single Mode fibre is capable of a distance of up to 10km. Uses 1310nm & 1490nm wavelengths, one for transmit, one for receive.

1000Base-CX - A version of Gigabit Ethernet over twinnax cable supporting a distance of up to 25m

1000Base-LH - Also known as 1000BaseLX10, a Gigabit Ethernet standard which due to higher quality fibre optics can achieve a longer distance (up to 10km) over Single Mode fibres than the 1000Base-LX Gigabit Ethernet standard

100Base-LX10 - A standard for 100Mbps over Single Mode fibre cable, using a pair of fibres and having a range of 10km. Uses 1310nm wavelength.

1000Base-LX - A Gigabit Ethernet standard over fibre optic with a maximum length of 50km for Single Mode fibre and 550m for Multi Mode fibre.

100Base-FX - A version of Fast Ethernet over multi-mode optical fibre with a maximum length of 400 metres for half-duplex connections and 20km for full duplex connections. Uses 1310nm wavelength

1000Base-T A Gigabit Ethernet standard over copper wiring using Category 5 or better cable with a maximum length of 100m. Is uses all 4 pairs of copper conductors.

100Base-TX - A standard for 100Mbps over copper cable. This can be any category of cable above 5e and uses 2 pairs of conductors. The maximum distance is 100m.

1000Base-TX - A Gigabit Ethernet standard over 2 pairs of copper, requiring Category 6 or better cable with a maximum length of 100m. There are very few products using this standard, it's sometimes quoted incorrectly.

100Base-SX - A standard for 100Mbps over Multi Mode fibre cable, which uses less expensive optics than 100Base-FX, but has a shorted range of 550m. Uses 850nm wavelength.

1000Base-SX - A version of Gigabit Ethernet over optical fibre using two strands of Multi Mode optical fibre to receive and transmit operating up to a distance of between 220m and 900m depending on the OM type of fibre used. Wavelength varies between 770nm-860nm.

10GBASE-ER - A 10Gb Ethernet standard for 'Extended Reach' connectivity over Single Mode fibre. The range is specified as 30km or 40km over engineered links. Uses 1550nm wavelength

10GBASE-LR - A 10Gb Ethernet standard for 'Long Reach' connectivity over Single Mode fibre. The range is specified as 10km however some devices can go up to 25km. Uses 1310nm wavelength

10GBASE-LRM - 'Long Reach Multi Mode' 10Gb Ethernet standard, enabling connectivity up to 220m over any type of Multi Mode fibre. This is especially useful if using over OM1 62.5/125 FDDI grade cable which is still widely used. Uses 1310nm wavelength.

10GBase-SR A 10Gb Ethernet standard for 'Short Range' connectivity over Multi Mode fibre. The range is limited from 33m to 400m depending on the type of fibre used. Uses 850nm wavelength

10GbE 10 Gigabit Ethernet - a version of Ethernet with a data of 10Gbit/s, 10 times faster than Gigabit Ethernet.

1Gb 1 Gigabit.

1RU One Rack Unit - measurement denoting the height of equipment for mounting in a 19" rack, 1 Rack Unit or 1U = 1.75" or 44.45mm in height. More commonly referred to as 1U.
