OWDM is an evolution of traditional Wavelength Division Multiplexing (WDM), which combines multiple optical signals at different wavelengths onto a single fiber to increase bandwidth and network capacity . Unlike conventional WDM, where channels are separated by fixed wavelength spacing and may suffer from crosstalk if spacing is too narrow, OWDM uses orthogonal spectral channels. This orthogonality ensures that even closely spaced channels do not interfere with each other, allowing denser channel packing and higher spectral efficiency.
OWDM is particularly useful in high-capacity optical networks, including:
In essence, OWDM extends the concept of WDM by using orthogonal channels, allowing optical networks to achieve higher capacity and efficiency while minimizing interference. It represents a key technology for next-generation optical communication systems where spectral efficiency and high data throughput are essential .

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.e., colors) of laser light.
