Most contractors assume it is necessary to field-terminate fiber optic cabling systems as part of every installation, but they are all looking for alternatives. The first alternative most people consider is to use prepolished/splice connectors, which use a mechanical splice to terminate the fiber.
Wireless devices—including laptops, netbooks (the smaller, less powerful and cheaper PCs), iPhones, Blackberrys and regular cell phones—now dominate the news. Wireless is everywhere. I even hiked recently in a 4,500 acre nature preserve that had full Wi-Fi coverage at 50 megabits per second!
One of the greatest advantages of the evolution of new, high-speed digital technology has been the ability to stay connected, informed and entertained in the home. Case in point, before the Internet, “telecommute” was not a household word.
Communications systems and circuits in buildings must comply with the applicable rules in National Electrical Code (NEC) 2008 Article 800. Even though these systems operate at lower energy levels, improper grounding and bonding can result in severe consequences for equipment, property and people.
A branch manager for an experienced cabling contractor with whom I have worked for years is known to get a special glimmer in his eye when he discovers extensive fiber optic cable in a project that he is bidding.
The corporate network is undergoing a major shift in emphasis that impacts cabling tremendously. The “traditional” corporate network that uses fiber optic backbones and category-rated unshielded-twisted pair (UTP) copper to the desktop is becoming a dinosaur.
Fujitsu Computer Products of America Inc., a supplier of computer products in Sunnyvale, Calif., and the University of California, Berkeley, released a jointly authored paper titled “Fujitsu 10Gb Ethernet Switches Enable Researchers to Study the Universe for Signs of Life,” which examines the univer
It was only a matter of time, and controlling bosses around the world probably won’t welcome the news. Thanks to telecommuters and other techno geeks who ply their trade at home, the worldwide installed base of home networks is expected to break the 200 million mark by the end of 2008.
True building integration means finding commonalities between building systems and using the appropriate communication protocols to program them. This provides cooperative sequences of operations that offer increased value to the building owner.
According to data from Connected Nation, state, local and national leaders must focus more attention on the consumer side of America’s broadband challenge. The nonprofit organization expands access to and use of the Internet and organization related technologies. U.S. Rep.
Phishing, pharming, hacking and malware are all terms most electrical or low-voltage contractors know a little about. Contractors at least know the damage such computer threats can do to their clients.
Contractors working in telecommunications or data communications may find applications of voice over Internet protocol (VoIP) confusing. In addition, the proper use of unshielded twisted pair (UTP) cabling may pose some challenges.
