  • Fiber optic cable as transmission medium

    Fiber optic cable as transmission medium

    Attenuation in fiber optics, also known as transmission loss, is the reduction in the intensity of the light signal as it travels through the transmission medium. Attenuation coefficients in fiber optics are usually expressed in units of dB/km. The medium is usually a fiber of silica glass that confines the incident light beam within. Attenuation is an important factor limiting the transmission of a digital signal across large distances.

Optical fiber is divided into SM fiber (Single Mode Fiber) and MM fiber (Multi Mode Fiber) according to the transmission mode. When the diameter is small, the light is. When light propagates into the center of the optical fiber, the refractive index n1 of the fiber core is higher than that of the cladding n2, and the loss of the core is lower than that of the cladding, so that the light will undergo total reflection, and its light energy is mainly transmitted in. A fiber optic cable (frequently shortened to “fiber cable”) is a specialized transmission medium crafted to carry data as light pulses through ultra-thin strands of glass or plastic known as optical fibers.
