Which of these cable types transmits data the greatest distance?
A . Multi-mode fiber
B . Single-mode fiber
C . Cat5e
D . Cat6
Answer: B
Explanation:
When working with distances up to 2 km, use multimode optical-fiber cable. Like multi-mode optical fibers, single mode fibers do exhibit modal dispersion resulting from multiple spatial modes but with narrower modal dispersion. Single mode fibers are therefore better at retaining the fidelity of each light pulse over longer distances than multi-mode fibers.
Incorrect: Cat5e and Cat6 max cable length is 100 metres.
