A fiber optic is made of three main parts, labeled in the figure to the right. The core, made of glass or plastic, provides the path for light propagation. Larger core sizes allow a larger amount of light, or a larger beam diameter, to enter the fiber. The numerical aperture (NA) of the core determines the range of incident angles the fiber can accept and still perform within its specified range. The cladding prevents light from exiting the core and being absorbed by the rest of the cable. The coating, or buffer, protects the core and cladding and provides strength.
When the fiber is manufactured into a cable, the next layer is a material, such as Kevlar, that provides strength to the cable and helps prevent damage due to stress. The entire package is then encased in a jacket. This outer jacket provides one last layer of protection and also adds strength to the fiber. The jacket is typically colored to help the user determine what type of optical fiber is in the cable.
Thorlabs follows the industry standard in jacket coloration. We use a yellow jacket for our Single Mode (SM) fibers, a orange jacket for our Multimode (MM) fibers, and a blue jacket for our Polarization Maintaining (PM) fibers.
How to fiber optic cable manufacturer
Both the core and the cladding of an optical fiber are made of highly purified silica glass. An optical fiber is manufactured from silicon dioxide by either of two methods. The first, the crucible method, in which powdered silica is melted, produces fatter, multimode fibers suitable for short-distance transmission of many light wave signals. The second, the vapor deposition process, creates a solid cylinder of core and cladding material that is then heated and drawn into a thinner, single-mode fiber for long-distance communication.
There are three types of vapor deposition techniques: Outer Vapor Phase Deposition, Vapor Phase Axial Deposition, and Modified Chemical Vapor Deposition (MCVD). This section will focus on the MCVD process, the most common manufacturing technique now in use. MCVD yields a low-loss fiber well-suited for long-distance cables.
