10BASE-F

10-Mbps baseband Ethernet specification that refers to the 10BASE-FB, 10BASE-FL, and 10BASE-FP standards for Ethernet over fiber-optic cabling. See also 10BASE-FB, 10BASE-FL, 10BASE-FP, and Ethernet.

10BASE-FB

10-Mbps baseband Ethernet specification using fiber-optic cabling. 10BASE-FB is part of the IEEE 10BASE-F specification. It is not used to connect user stations, but instead provides a synchronous signaling backbone that allows additional segments and repeaters to be connected to the network. 10BASE-FB segments can be up to 2000 meters long. See also 10BASE-F and Ethernet.

10BASE-FL

10-Mbps baseband Ethernet specification using fiber-optic cabling. 10BASE-FL is part of the IEEE 10BASE-F specification and, while able to interoperate with FOIRL, is designed to replace the FOIRL specification. 10BASE-FL segments can be up to 1000 meters long if used with FOIRL, and up to 2000 meters if 10BASE-FL is used exclusively. See also 10BASE-F, Ethernet, and FOIRL.

10BASE-FP

10-Mbps fiber-passive baseband Ethernet specification using fiber-optic cabling. 10BASE-FP is part of the IEEE 10BASE-F specification. It organizes a number of computers into a star topology without the use of repeaters. 10BASE-FP segments can be up to 500 meters long. See also 10BASE-F and Ethernet.

10BASE-T

10-Mbps baseband Ethernet specification using two pairs of twisted-pair cabling (Category 3, 4, or 5): one pair for transmitting data and the other for receiving data. 10BASE-T, which is part of the IEEE 802.3 specification, has a distance limit of approximately 100 meters per segment. See also Ethernet and IEEE 802.3.

10Broad36

10-Mbps broadband Ethernet specification using broadband coaxial cable. 10Broad36, which is part of the IEEE 802.3 specification, has a distance limit of 3600 meters per segment. See also Ethernet and IEEE 802.3.

10 Mbps

Millions of bits per second. A unit of information transfer rate. Ethernet carries 10 mbps.

100BASE-FX

100-Mbps baseband Fast Ethernet specification using two strands of multimode fiber-optic cable per link. To guarantee proper signal timing, a 100BASE-FX link cannot exceed 400 meters in length. Based on the IEEE 802.3 standard. See also 100BASE-X, Fast Ethernet, and IEEE 802.3.

100BASE-T

100-Mbps baseband Fast Ethernet specification using UTP wiring. Like the 10BASE-T technology on which it is based, 100BASE-T sends link pulses over the network segment when no traffic is present. However, these link pulses contain more information than those used in 10BASE-T. Based on the IEEE 802.3 standard. See also 10BASE-T, Fast Ethernet, and IEEE 802.3.

100BASE-T4

100-Mbps baseband Fast Ethernet specification using four pairs of Category 3, 4, or 5 UTP wiring. To guarantee proper signal timing, a 100BASE-T4 segment cannot exceed 100 meters in length. Based on the IEEE 802.3 standard. See also Fast Ethernet and IEEE 802.3.

100BASE-TX

100-Mbps baseband Fast Ethernet specification using two pairs of either UTP or STP wiring. The first pair of wires is used to receive data; the second is used to transmit. To guarantee proper signal timing, a 100BASE-TX segment cannot exceed 100 meters in length. Based on the IEEE 802.3 standard. See also 100BASE-X, Fast Ethernet, and IEEE 802.3.

100BASE-X

100-Mbps baseband Fast Ethernet specification that refers to the 100BASE-FX and 100BASE-TX standards for Fast Ethernet over fiber-optic cabling. Based on the IEEE 802.3 standard. See also 100BASE-FX, 100BASE-TX, Fast Ethernet, and IEEE 802.3.

100VG-AnyLAN

100-Mbps Fast Ethernet and Token Ring media technology using four pairs of Category 3, 4, or 5 UTP cabling. This high-speed transport technology, developed by Hewlett-Packard, can be made to operate on existing 10BASE-T Ethernet networks. Based on the IEEE 802.12 standard. See also IEEE 802.12.
