General ETHERNET transmission standards
For transmitting data the ETHERNET standard supports numerous
technologies with various parameters (e.g., transmission speed, medium,
segment length and type of transmission).
Tab. 4-1: ETHERNET Transmission Standards
Beyond that there are still further transmission standards, for example:
100Base-T4 (Fast ETHERNET over twisted conductors), 100Base-FX (Fast
ETHERNET over fiber-optic cables) or P802.11 (Wireless LAN) for a
wireless transmission.
The media types are shown with their IEEE shorthand identifiers. The IEEE
identifiers include three pieces of information.
The first item, for example, “10”, stands for the media.
The third part of the identifier provides a rough indication of segment type or
length. For thick coaxial cable, the “5” indicates a 500 meter maximum length
allowed for individual thick coaxial segments. For thin coaxial cable, the “2”
is rounded up from the 185 meter maximum length for individual thin coaxial
segments. The “T” and “F” stand for ‘twisted pair’ and ‘fiber optic’, and
simply indicate the cable type.
Uses a 24 AWG UTP (twisted pair cable) for a 1Mbps baseband signal for
distances up to 500 m (250 m per segment) in a physical star topology.
Uses a 5 mm 50 Ohm coaxial cable for a 10Mbps baseband signal for distances
of up to 185 m in a physical bus topology (often referred to as Thin ETHERNET
or ThinNet).
Uses a 10 mm 50 Ohm coaxial cable for a 10Mbps baseband signal for distances
of up to 500 m in a physical bus topology (often referred to as Thick
ETHERNET).
Uses a fiber-optic cable for a 10Mbps baseband signal for distances of up to
4 km in a physical star topology.
(There are three sub-specifications: 10Base-FL for fiber-optic link, 10Base-FB
for fiber-optic backbone and 10Base-FP for fiber-optic passive).
Uses a 24 AWG UTP or STP/UTP (twisted pair cable) for a 10Mbps baseband
signal for distances up to 100 m in a physical star topology.
Uses a 75 Ohm coaxial cable for a 10Mbps baseband signal for distances of up
to 1800 m (or 3600 m with double cables) in a physical bus topology.
RJ45-connectors. A maximum segment of 100 meters may be used.
