Almost every wavelength (often referred to as hue or frequency) between roughly 670 nm and 1550 nm may be found in real light. Less expensive LEDs were used by fiber optic data
How Wavelength Division Multiplexing (WDM) Works
Each data stream is first converted into pulses of laser light, with each stream assigned a unique, precise wavelength, comparable to assigning a specific radio frequency to each radio station.
Wavelength division multiplexing
For this system, there is some cross-talk between the channels, and the results can be improved by modifying the ring modulators/resonators to have a larger FSR, and increasing the bandwidth of each
Wavelength Division Multiplexing
Wavelength division multiplexing is a technology where multiple optical signals with different wavelengths are combined for transmission through a single optical fiber and are later separated.
