Single-mode fiber optic cable consists of a single glass or plastic core with a diameter of about 8–10 microns, surrounded by cladding with a lower refractive index . This small core allows only one mode of light to propagate, minimizing signal attenuation and dispersion, which makes it ideal for long-distance, high-speed communication . Light signals are transmitted using laser sources precisely aligned to the fiber core, ensuring accurate and reliable data transfer . Single-mode fiber is commonly used in telecommunications, internet backbones, and data centers .
WDM allows a single fiber to transmit and receive simultaneously by using different wavelengths for each direction . A WDM transceiver separates the wavelengths, preventing interference between the transmitted and received signals. Key points include:
This method uses the same wavelength in both directions and combines signals using a power coupler . The system is designed so that back-reflected light remains below the noise floor, allowing simultaneous transmission and reception without significant interference.
Traditionally, two fibers are used: one for transmitting and one for receiving. While simple, this doubles the fiber requirement and is less efficient for single-strand deployments .
To transmit and receive signals over a single-mode fiber:
