15 Nov Optical Networks
The increasingly popular optical networks can be found almost everywhere. The largest increase in optical connections in Slovenia occurred with the construction of optical connections to the home, the so-called FTTH (Fiber To The Home).
An optical network uses optical fibers instead of copper conductors. Fiber optic communication is a method of transmitting information from one point to another by sending pulses of infrared or LED light through the fiber optic core. The light pulse forms an electromagnetic carrier wave that is modulated to carry information.
Active equipment that transmits information converts an electrical pulse into a light pulse and sends it through an optical fiber to a receiver. At the destination, the light pulse is converted into an electrical one for use in e.g. computer, modem, etc.
The biggest advantage of optical fibers over cables with copper conductors is that they have a much higher bandwidth and thus the speed of information transfer. Optical fiber has very low energy loss, which allows for longer transmission distances, and since optical fibers are made of glass, they are not susceptible to power outages.
Optical fibers have evolved over the years and there are three types of optical fibers in general use – Singlemode (single mode), multimode (multimode) and POF (plastic optical fiber). Singlemode fibers are most commonly used for applications where high speed and distance are required. Multimode fibers are most often used for internal or internal distribution of communications. Plastic optical fibers (or TOSLINK) are most commonly used in the music industry.
Singlemode fibers contain a 9µm diameter core in a 125µm cladding, typically labeled 9/125µm. According to the purity of the core, they are divided into OS1 (approx. 1998 years) and OS2 (approx. 2000 years).
The first multimode fibers initially (approx. in 1989) contained a 62.5 µm core called OM1. Later, the fiber was improved with a 50µm core, named OM2 (ca.1998), then OM3 (around 2003), OM4 (2008) and OM5 (2016). With each upgrade of the core, or with a higher purity of the core in the fiber, the speed and distance between the transmission points increased.
At Monel pro doo, in cooperation with suppliers, we can offer you all types of singlemode and multimode cables, splitters, connection cables and other equipment.
