Copper remains a primary carrier for integrated building systems, but fiber optic cabling is assuming an increasingly important role in data, telephone, access controls, security cameras, fire and security alarms, sensors, and other signaling-dependent systems.
I’m sure you’ve heard that you need the right tool for the job, but have you ever considered that you might need the right tool for you? Nothing affects how easily a job can be done as much as having the correct tools and knowing how to use them properly.
Fiber optic installers make some common, avoidable mistakes that cause problems for them and their customers. Do you know about these mistakes and how to avoid them? Correct answers and explanations are in red.
While most users in an enterprise network want mobile devices connected over Wi-Fi or cellular wireless networks, a large number of users still have cable connections. Generally, these users require high bandwidth and processing speeds and/or secure connections.
I often get calls from contractors in trouble. Usually, it is because they find some requirement in a contract that they have overlooked, and usually, that requirement is going to cost them a lot of money to meet.
Last month, I discussed the issues of industry standards for fiber optic and copper cabling. Manufacturers write standards so they can build products that are compatible with products from other manufacturers, since multiple sources are mandatory in today’s marketplace.
Practically every aspect of fiber optics, especially network design, testing and troubleshooting, depends on understanding optical power. Sometimes, something so basic gets overlooked, so let’s test your understanding of it. Correct answers and explanations are in red. 1.
Before the last meeting of the TIA TR-42 committees that write cabling standards, a major fiber optic test equipment company asked if I would petition one of the committees to reconsider OFSTP-14, a new standard for testing installed multimode cable plants.
The original intent of this month’s column was to discuss fiber use in the smart grid, but I have found it is hard to define the smart grid. Some organizations involved in it are even dropping that name for “intelligent grid” or something similar.
Not all fiber optic systems are the same, and one big difference is the wavelength used for transmission. The wavelength affects performance, testing and the choice of components, so let’s see how well you understand it. Correct answers and explanations are in red. 1.
Those of us who have been in fiber optics for a long time have gotten tired of hearing about the “advantages of fiber optics,” e.g., higher bandwidth, longer distance capabilities and immunity to electrical interference.
While most of the talk about expanding broadband access for the American public has focused on rural customers, much of the activity is in metropolitan areas. Metro networks are expanding rapidly because they encompass many types of networks, not just broadband Internet.
Around the world, billions of dollars are being spent trying to bring “broadband” to everyone. However, broadband is defined loosely. Some say anything over 1 megabit per second (Mbps) is broadband, while others are looking at much higher speeds.
As networks get faster, cabling to support them needs upgrading. Outside plant networks, most of which run on single-mode fiber optic cable with its almost infinite bandwidth, are rarely in need of upgrading. On the other hand, premises cabling usually needs to be upgraded.
