A network technician is assembling custom Category 6 patch cables to connect desktop computers to wall outlets. After terminating a newly cut cable, the technician uses a wire mapper to test pin continuity and discovers that pins 1, 2, 3, and 6 on one connector map to pins 3, 6, 1, and 2 respectively on the opposite connector. Which error did the technician make during cable termination?
- The technician wired one end of the cable using the T568A standard and the other end using the T568B standard.Cevap
- BThe technician attached unshielded RJ45 connectors to a shielded Category 6 twisted-pair cable run.
- CThe technician stripped too much outer cable jacket, leading to excessive near-end crosstalk between pairs.
- DThe technician used legacy Category 5e RJ45 modular plugs instead of Category 6 rated connectors.
Cevap
The technician wired one end of the cable using the T568A standard and the other end using the T568B standard.
Combining T568A on one end of an Ethernet cable and T568B on the opposite end transposes the orange and green wire pairs. This results in pins 1 and 2 connecting to pins 3 and 6, which creates a crossover cable rather than the intended straight-through connection.
