A fiber run stays inside one building and is specified for many paths of light rather than a single laser path. Which fiber matches that specification?
Select an answer to reveal the explanation.
Short Explanation
The specification wants many light paths inside one building, not one laser path across a long haul. You use multimode fiber. A single path, a copper coax line, and a shielded copper pair are not that fiber.
Full Explanation
Multimode fiber carries multiple paths of light and is the usual choice for a short run inside a building. The specification asks for many paths rather than a single laser path, so multimode is the match. Single-mode is the single path, used for long runs. Calling it the many-path design reverses the two. Coaxial cable carries an electrical signal, not paths of light. Shielded twisted pair is copper built to reject interference. It is not fiber. Exam caveat: the optic on each end has to match the fiber. A single-mode optic on multimode fiber is not a completed link. Operational check: install the multimode run, connect matching optics, and confirm the link light at both ends. Label both ends so the next person does not patch a single-mode cord onto this run.
