The system is composed of 4 RFoF bi-directional terminals that are connected to each other by 4 single mode fibers (SMF). In order to achieve low-cost scalability, the same-wavelength bidirectional (SWB) fiber communication system is a better solution.

The abbreviation "nm" stands for nanometer, a unit of measurement equal to one billionth of a meter (1 nm = 10^-9 meters). In fiber optic communication, nm is used to denote the wavelength of light used by the optical modules to transmit data. Why do we use the infrared? Because the attenuation of the fiber is much less at those wavelengths. That value determines whether the module is designed for multimode fiber (MMF) or single-mode fiber (SMF), how much attenuation the signal will experience, how dispersion behaves over distance, and whether optical amplification or DWDM systems are possible.

Modern fiber-optic communication systems generally include optical transmitters that convert electrical signals into optical signals, optical fiber cables to carry the signal, optical amplifiers, and optical receivers to convert the signal back into an electrical signal. First developed in the 1970s, fiber-optics have revolutionized the industry and have played a major role in the advent of the.

The transmission distance of a fiber-optic communication system has traditionally been limited by fiber attenuation and by fiber distortion.
