2. Twisted pair - Wikipedia

   en.wikipedia.org/wiki/Twisted_pair

   Twisted pair cabling is a type of communications cable in which two conductors of a single circuit are twisted together for the purposes of improving electromagnetic compatibility. Compared to a single conductor or an untwisted balanced pair , a twisted pair reduces electromagnetic radiation from the pair and crosstalk between neighboring pairs ...

3. Differential signalling - Wikipedia

   en.wikipedia.org/wiki/Differential_signalling

   The pair of conductors can be wires in a twisted-pair or ribbon cable or traces on a printed circuit board. Electrically, the two conductors carry voltage signals which are equal in magnitude, but of opposite polarity. The receiving circuit responds to the difference between the two signals, which results in a signal with a magnitude twice as ...

4. Telephone line - Wikipedia

   en.wikipedia.org/wiki/Telephone_line

   Cross section of telephone cable of 1,800 twisted pairs, 1922. A telephone line or telephone circuit (or just line or circuit industrywide) is a single-user circuit on a telephone communication system. [1] It is designed to reproduce speech of a quality that is understandable. [2]

6. 25-pair color code - Wikipedia

   en.wikipedia.org/wiki/25-pair_color_code

   The 25-pair color code, originally known as even-count color code, [1] is a color code used to identify individual conductors in twisted-pair wiring for telecommunications. Color coding [ edit ]

7. Ethernet over twisted pair - Wikipedia

   en.wikipedia.org/wiki/Ethernet_over_twisted_pair

   Ethernet over twisted-pair technologies use twisted-pair cables for the physical layer of an Ethernet computer network. They are a subset of all Ethernet physical layers . Early Ethernet used various grades of coaxial cable , but in 1984, StarLAN showed the potential of simple unshielded twisted pair .

8. Low-voltage differential signaling - Wikipedia

   en.wikipedia.org/wiki/Low-voltage_differential...

   Basic LVDS circuit operation showing current flowing in a loop back to the driver and the resulting lower radiated emission (EMI) due to field coupling within the differential pair Low-voltage differential signaling ( LVDS ), also known as TIA/EIA-644 , is a technical standard that specifies electrical characteristics of a differential , serial ...

9. Wire wrap - Wikipedia

   en.wikipedia.org/wiki/Wire_wrap

   It is unique among automated prototyping techniques in that wire lengths can be exactly controlled, and twisted pairs or magnetically shielded twisted quads can be routed together. Wire wrap construction became popular around 1960 in circuit board manufacturing, and use has now sharply declined.
