Glossary
- 4B/5B
A block encoding scheme used to send Fast Ethernet data. In this signal encoding scheme, 4 bits of data are turned into 5-bit code symbols for transmission over the media system.
- 4D-PAM5
A block encoding scheme used for 1000BASE-T twisted-pair Gigabit Ethernet that transmits signals over four wire pairs. This coding scheme translates an 8-bit byte of data into a simultaneous transmission of four code symbols (4D) that are sent over the media system as 5-level Pulse Amplitude Modulated (PAM5) signals.
- 50-pin connector
A connector that is sometimes used on 10BASE-T hubs as an alternate twisted-pair segment connection method. The 50-pin connector is used to connect 25-pair cables used in telephone wiring systems, which are typically rated to meet Category 3 specifications. Commonly referred to as a Telco, CHAMP, or “blue ribbon” connector.
- 8-pin connector
A twisted-pair connector that closely resembles the RJ45 connector used in US telephone systems, but has significantly better electrical characteristics than typical telephone-grade RJ45 connectors.
- 8B6T
A block encoding scheme used in 100BASE-T4 systems, based on translating 8-bit (binary) data patterns into 6-bit code symbols that are transmitted as 3-level (ternary) signals.
- 8B/10B
A block encoding scheme used in 1000BASE-X Gigabit Ethernet systems, in which 8-bit bytes of data are translated into 10-bit code symbols.
- 10BASE-T
10 Mb/s Ethernet system based on Manchester signal encoding transmitted over ...
