The basic design of a 980/1550nm Fused WDM involves carefully controlled fiber fusion and tapering processes. These components use specialized optical fibers that, when properly fused together, create precise wavelength-selective coupling regions. The light from each fiber is first collimated. Wavelength division multiplexing is a method of modulating multiple signals at different wavelengths (channels) to transmit them on a single waveguide or fiber. To begin with, we assume that we have the element.
