Wavelength division multiplexing greatly improves performance

Known for its ability to enhance the utility and performance of fiber optic cables, WDM has become a reliable method for increasing bandwidth while maintaining seamless connectivity. Current solutions are limited by trade-offs between channel spacing, crosstalk, insertion. In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.
