3. Cable tester - Wikipedia

   en.wikipedia.org/wiki/Cable_tester

   A simple tester for BNC and twisted pair cabling. A cable tester is an electronic device used to verify the electrical connections in a signal cable or other wired assembly. Basic cable testers are continuity testers that verify the existence of a conductive path between ends of the cable, and verify the correct wiring of connectors on the cable.

4. Wire speed - Wikipedia

   en.wikipedia.org/wiki/Wire_speed

   In computer networking, wire speed or wirespeed refers to the hypothetical peak physical layer net bit rate (useful information rate) of a cable (consisting of fiber-optical wires or copper wires) combined with a certain digital communication device, interface, or port. For example, the wire speed of Fast Ethernet is 100 Mbit/s [1] also known ...

5. Time-domain reflectometer - Wikipedia

   en.wikipedia.org/wiki/Time-domain_reflectometer

   It is only after this round-trip delay that the short can be detected by the TDR. With knowledge of the signal propagation speed in the particular cable-under-test, the distance to the short can be measured. A similar effect occurs if the far end of the cable is an open circuit (terminated into an infinite impedance).

6. Copper cable certification - Wikipedia

   en.wikipedia.org/wiki/Copper_cable_certification

   The propagation delay test tests for the time it takes for the signal to be sent from one end and received by the other end. Delay skew. The delay skew test is used to find the difference in propagation delay between the fastest and slowest set of wire pairs. An ideal skew is between 25 and 50 nanoseconds over a 100-meter cable. The lower this ...

7. Optical Carrier transmission rates - Wikipedia

   en.wikipedia.org/wiki/Optical_Carrier...

   Transmission rates are defined by rate of the bitstream of the digital signal and are designated by hyphenation of the acronym OC and an integer value of the multiple of the basic unit of rate, e.g., OC-48. The base unit is 51.84 Mbit/s. [2] Thus, the speed of optical-carrier-classified lines labeled as OC-n is n × 51.84 Mbit/s.
