Practical Applications of Graded Index Multimode Fiber

Posted by Jonathan Benfield on Tue, Aug 3, 2021 @ 09:08 AM

Communications engineers face many complicated decisions when selecting the most appropriate type of fiber optic cabling for their specific needs. Should the fiber be single mode or multimode? If it is multimode, should it be step index fiber or graded index? Those are just two of the multitude of questions that need to be answered when selecting the best fiber solution.

What is Wavelength Division Multiplexing (WDM)?

WDM is a technology approach that allows for the combining ("mux") of multiple individual light wavelengths (signals/channels) from multiple lasers on a single fiber using a passive component for transmission to another location. At that receiving location, WDM components then work in the reverse, demultiplexing ("demux") the combined wavelengths back into individual signals and routed to their respective receivers.
