1.2 Terms explanation
10BASE-T
A term in IEEE 802.3 for Ethernet over CAT-3 or better twisted pair,
based on Manchester coding and running at 10Mbps.
100BASE-TX
A term in IEEE 802.3 for Fast Ethernet over CAT-5 twisted pair, based on
4B/5B coding and running at 100Mbps.
1000BASE-X
A term in IEEE 802.3 for Gigabit Ethernet over fiber, based on 8B/10B
coding and running at 1000Mbps.
Auto
Negotiation
The auto negotiation procedure is: the port at one site adapts its bit rate
and duplex mode to the highest level it and the opposite site device both
support according to the bit rate and duplex mode adopted by the remote
site device, that is, the connected devices on both site adopt the fastest
transmission mode they both support after the auto negotiation process.
Full Duplex
A communication pattern that allows communication in both directions
simultaneously.
Half Duplex
A communication pattern that allows communication in both directions,
but only one direction at one time.
RJ-45
The 8 position modular connector applied in twisted pair cable link
MDI
Medium Dependent Interface, the name for the connector physically and
electrically connects the media converter and the media segment.
MDIX
Medium Dependent Interface Crossover, it sends the transmitting signal
of a device to the receiving port of the opposite device and vice versa.
