Is the signal from a cable or fiber optic cable
Fiber optic cables use light to transmit data, whereas traditional cables rely on electrical signals, which are more prone to interference and loss over distance. The light is a form of carrier wave that is modulated to carry information. Where traditional copper cables max out at about 10 gigabits per second, fiber optic cables can handle 100 gigabits per second with commercially available hardware, and. The primary difference between fiber optic and cable internet is the transmission medium used for data transmission.

Optical cable loss and attenuation value
Fiber optic loss calculation formula: Total link loss (LL) = Cable attenuation + Connector attenuation + Fusion attenuation [Note: If there are other components (such as attenuators), their attenuation values can be added]. Losses can be introduced by various means such as intrinsic material absorption, scattering, bending, connector loss and more. The OH+ absorption is predominant, and occurs most strongly around 1000 nm, 1400 nm and above1600 nm. Total attenuation is the sum of all losses. Optical losses of a fiber are usually expressed in decibels per kilometer (dB/km). So, how can we know the loss value on the fiber optic link? This article will teach you how to calculate the loss in the fiber. Optical fiber is a medium to carry information.
