Optical attenuation in multimode optical cables
Although attenuation is significantly lower for optical fiber than for other media, it still occurs in both multimode and single-mode transmissions. They spray varying wavelengths of light into the multimode fiber, which reflects the light at different angles. We concentrate here on the measurement of attenuation of multimode, telecommunication-grade fibers for the wavelength range of 850 nm to 1300 nm. The attenuation coefficient is measured in decibels per kilometer (dB/km) and is determined by several factors, including the type of fiber used in the cable, the.
