Question: 1 / 400

In fiber optic cabling, what does the notation 62.5/125 indicate?

The length of the cable

Core’s diameter and cladding’s diameter

The notation 62.5/125 in fiber optic cabling specifically refers to the diameters of the core and cladding of the fiber. In this case, 62.5 micrometers is the diameter of the core, which is the part of the fiber where the light is transmitted, while 125 micrometers is the diameter of the cladding that surrounds the core. The difference in these diameters is crucial because it influences the performance characteristics of the fiber, including how much light can be transmitted and at what efficiency.

Understanding this notation aids in recognizing how fiber optics work, particularly the importance of the core size in relation to the wavelength of the light being used and the total internal reflection that occurs within the fiber. This is essential for ensuring compatibility with light sources and connectors during installation and maintenance of fiber optic networks.
