Drag and Drop Question Drag and drop the characteristic from the left onto the cable type on the right. Answer:
The correct answer is uses a single wavelength of light; has a core diameter of 9 microns; is comprised of shielded and unshielded twisted pairs; contains a conductor, bedding, and sheathing. Single-mode fiber optic cable uses a single wavelength (mode) of light and has a narrow core diameter of 9 microns, which together minimize signal dispersion over long distances. Screened/hybrid copper cabling (such as ScTP or mixed cable bundles) is comprised of both shielded an

Explanation
Single-mode fiber optic cable uses a single wavelength (mode) of light and has a narrow core diameter of 9 microns, which together minimize signal dispersion over long distances. Screened/hybrid copper cabling (such as ScTP or mixed cable bundles) is comprised of both shielded and unshielded twisted pairs. Coaxial cable is constructed with a central conductor, bedding (dielectric insulator), and an outer sheathing, distinguishing it from twisted-pair and fiber options.
