Which of the following cables has a hard plastic cross inside the cable to separate each pair of wires?
The correct answer is D. CAT6a. CAT6a (Category 6a) cable often includes a hard plastic cross-shaped separator called a spline or star separator that physically divides the four twisted pairs inside the cable. This internal structure reduces alien crosstalk (interference from adjacent cables), which is…

Explanation
CAT6a (Category 6a) cable often includes a hard plastic cross-shaped separator called a spline or star separator that physically divides the four twisted pairs inside the cable. This internal structure reduces alien crosstalk (interference from adjacent cables), which is critical for CAT6a's support of 10 Gbps at up to 100 meters. Coaxial cable has a single conductor with a shielding layer. CAT3 and CAT5 are older UTP cables with twisted pairs but no internal plastic separator.
