lti-core processors, and memory-are the building blocks of modern networks. They enable networks to carry more information faster. Decreasing memory costs have led to affordable personal computers and the ability to store vast amounts of information, accessible via fiber-optic-based networks at lower costs. Fiber-Optic Cabling: Underpinning High-Speed Networks Without fiber-optic cabling, modern high-speed data networks would not be possible. Fiber-optic cabling is the glue connecting all high-speed networks to the cloud, and to other continents. Fiber networks are located www.TechnicalPDF.com between cities; undersea in oceans; within cities; and on university, business, and hospital campuses. Sophisticated equipment and computer chips are enabling fiber networks to keep up with the growing demand for capacity on broadband networks. Demand for bandwidth is a result of cloud computing, subscribers streaming movies and television shows, online gamers, real-time coverage of live sporting events, and international news. People expect instant access to breaking news, social networks such as Facebook, QQ, and Weibo, and entertainment. (Chinese company Tencent owns QQ and a different Chinese company, Sina owns Weibo.) Fiber-optic networks support broadband connections to the Internet, which enable streaming TV services such as Netflix and Amazon; streaming music providers including Apple Music, Pandora, and Spotify; and social networks. The world has gotten smaller and businesses and people expect to be able to remain connected wherever and whenever they want. Because of dropping prices of installation and lower maintenance costs, network providers including AT&T, Verizon, and CenturyLink are increasingly connecting fiber-optic networks to apartment buildings and even individual homes. Traffic on fiber-optic cabling is not limited to these networks. It is also growing in cellular networks that use fiber-optic cabling to carry data- and video-heavy smartphone traffic between antennas and mobile providers' data centers i
