3 1 Training Solution 1.1 Background Introduction During the past years, information and communication technologies (ICT) continued to spread throughout the world, and more people have access to the Internet and its wealth of information and applications. The last decades have seen uninterrupted growth in terms of telecommunication and ICT infrastructure development and service uptake. By the end of 2014, some 2.9 billion people or 40% of the global population will be online (ITU, 2014). At current growth rates, half of the world s population will be online by In order to process the increment of data traffic, investments in super high-speed communication systems are needed. Broadband has been referred to as the infrastructure of the knowledge economy. Countries around the world have nominated broadband networks as crucial infrastructure for achieving their social, economic and scientific goals. To provide the fixed broadband network, the construction of the cable network, i.e. fiber optic, twisted pair, coaxial cable etc. is crucial, which involving the outside plant (OSP) and indoor cabling. 1.2 Overview Telecommunications OSP cabling began with the placement of the first telegraph system, which consisted of wires linking two stations. From this simple beginning, OSP has expanded into a vast global telecommunications infrastructure. OSP is defined as the telecommunications infrastructure that is designed and installed externally to buildings and typically routed into an entrance facility. OSP may include: Optical fiber cabling. Balanced twisted-pair cabling. Coaxial cabling. Supporting structures required to link serving facilities to outlying locations and enable voice, data, video, and other low-voltage systems. Telecommunications deregulation gives independent contractors access to OSP contracts and creates opportunities for qualified OSP designers in today s open and competitive market. An OSP designer is responsible for designing the interbuilding cabling and entrance facility infrastructure and the termination of the OSP cabling. An OSP designer should have knowledge of the following OSP aspects: Pathways and spaces Cabling (cable and connecting hardware) Bonding and grounding (earthing) Right-of-way System documentation Codes and standards COMMERCIAL IN CONFIDENCE 3
