Fiber optic cabling is a high-speed medium capable of spanning large distances. However, there are different types of fiber optic cables. This video distinguishes between multimode and single mode fiber optics and gets into the science of how light waves are carried within a fiber strand.
"Fiber Optics" is a sample excerpted from Cisco CCENT ICND1 100-101 (Complete Video Course), a comprehensive, 17+ hour training course that brings Cisco CCENT exam topics to life through the use of real-world demonstrations, animations, live instruction, and configurations, making learning these foundational networking topics easy and fun.
