PRODUCTS - OPTICAL NETWORKS Because of new kinds of services like VoIP, VoD/IPTV, internet access, video conference, surveillance, on-line games… we encounter extraordinary requirements for band width, short response times and the need for mechanisms that allow the direction of traffic with regard to priority (QoS-Quality of Service). To meet these expectations we build networks with fiber optic cables. Optical communication is a new technology which is only 30 years old but is evolving rapidly with the ever-growing need for larger transfer capacities. It is only a matter of time until communication via fiber optics becomes the basic and main medium for long and middle and ultimately also short distance connections. In optical communication the transmitting equipment and the receiving equipment is connected through fiber optics. Advantages of fiber optics compared to electric wire: They distinguish themselves through their high bandwidth, which measures in the range of 1 to 10 Gigahertz; loss of signal is incomparably lower than in metal conductors. They are totally non conducting and therefore indifferent to electromagnetic disturbances and strokes of lightning. They cannot be listened in on the loss of signal does not depend on the speed of transfer. They are light and make higher density of fitting possible. They enable a total safety of data. The only drawback is the higher complexity of communication equipment and the slightly higher costs. Nonetheless the development in this area is very aggressive and successful so that prices of active equipment are getting lower all the time. Kinds of optical connection In the construction of structured cabling: " The Campus Backbone, the main optical connection between buildings, connects the central node of a group of objects to the main nodes of the individual objects. Most of the time, fiber optic cable is used in the central tube, which requires welding and the use of cable end clamps. "The Building Backbone is the main connection inside of buildings which connects the nodes on the individual floors of an object. In this case optical cables in the central tube require welding and cable end clamps or braided Breakout cables which make direct fitting of connectors possible. "The horizontal optic connection to the individual workplace and user, the Fiber to the Desk, uses braided optic MiniBreakout cables, which allow the direct fitting of connectors. In building the network from the node of the local center to the residence of the user: FTTH P2P - Fiber to the home point to point is a very simple and at the same time the best solution. In this case the optical pairs are led from the source directly to the user which enables an extraordinary high transfer capacity. Because of the higher price of such an arrangement hybrid models have appeared which lower the short term investment costs. FTTH PON – A Passive Optical Network shares a common optic network with passive elements where media are accessed with mechanisms (TDMA, WDMA, CDMA…). WDM (Wavelength Division Multiplexing), Wavelength Multiplexing allows for additional increase in transfer capacity of the individual fiber beyond the boundaries of the time-division multiplexing. • FTTx (x - curb, cabinet, street), optics are drawn from the center to suitable cabinets in distance of up to 300m to the user. Already installed or new paired copper wires are used to connect from the node to the user. Bavaria-iT has a lot of practical experience in the execution of passive optical networks. We have a variety of special tools and instruments for the finishing and installing as well as various measurements at our disposal. Our workers are qualified and have attained certificates of world renowned manufacturers.
