After Corning had invented the low-loss fiber in 1970, this optimised optical fiber became the foundation for all major telecom networks and for the current Internet. The characteristics of these Optical fibers are the extremely fast transmission speeds, a safe, undisturbed connection that cannot be listened into and reduced costs compared to traditional copper cables. With Optical fibers, information can be transported over great distances, whether we are talking about telecom, data or video-files. Infraconcepts supplies Optical fibers for any size of project or network.
Optical fibers are available in various types for different kinds of networks, like backbone-, access- or company networks. All with the purpose of creating fast connections. These optical fibers are easy to link by using fusion splicing.
Signals are transported at high speed by means of laser light, and the transmission takes place at the wavelengths of 1310, 1550 and/or 1625 nanometre (nm) for the single-mode fibers, and for the multi-mode fibers at 850 and/or 1300 nanometre (nm). Single-mode fibers are used for data signal-transmission across substantial distances (e.g. FTTx, CATV, metro and access networks), and multi-mode for shorter distances (for example in enterprise networks).
When choosing a solution it is important, therefore, to consider not only the cable set-up, but also to select the right single-mode or multi-mode optical fiber.
Single-mode optical fibers have a core-diameter of 8-10 micron, which is covered in a cladding of 125 micron.
The most frequently used single-mode optical fibers:
Multi-mode optical fibers have a core-diameter of 50 micron or 62.5 micron, which is covered with a cladding of 125 micron.
The most frequently used multi-mode optical fibers:
