The choice of premises fiber optic components is affected by -several factors, including communications equipment, physical routing of the cable plant and building codes and regulations. If the design is a corporate local area network (LAN), the design will probably include a fiber optic backbone, connecting computer rooms to wiring closets. READ MORE

The choice of outside plant (OSP) fiber optics components begins with last month’s work: developing the route the cable plant will follow. Once the route is set, it is certain where cables will be run, where splices are located and where the cables will be terminated. All that determines which choices must be made on cable type, hardware and sometimes installation methodology. READ MORE

From the technology with which Alexander Graham Bell yelled, “Mr. Watson, come here!” to crank, dial and touch-tone phones and continuing with Ethernet from 10 million bits per second to 10 billion, a pair of copper wires has been the mainstay of communications. Needless to say, some serious technical development was required to get to today’s cables. READ MORE

Having decided to use fiber optics and chosen equipment appropriate for the application, it is time to determine exactly where the cable plant and hardware will be located. One thing to remember: Every installation is unique. READ MORE

Recently, I heard a report on National Public Radio about a crisis in office computer networks. Employees were watching the NCAA “March Madness” basketball games online, hogging bandwidth and slowing corporate networks to a crawl. This is an example of why network bandwidth, and eventually the cable plant itself, is so important. READ MORE

Once a communications cable is installed, proof of proper installation is needed to get the customer to accept it (and pay your bill). What are ­the options on testing, certifying and/or verifying the cabling? Correct answers and explanations are in red. READ MORE

Choosing transmission equipment is the next step in designing a fiber optic network. This step usually will be a cooperative venture involving the customer, who knows which types of data they need to communicate; the designer and installer; and the manufacturers of transmission equipment. Transmission equipment and the cable plant are tightly interrelated. READ MORE

While the debate over which is better—copper, fiber or wireless—has enlivened cabling discussions for decades, it is becoming moot. Communications technology and the end-user market, it seems, already have made decisions that generally dictate the media. READ MORE

Many years ago, people complained that the most dangerous part of fiber optic work was the chance you might get your eyeballs burned by laser light in the fiber. They had confused optical fibers to the output of high-powered lasers used in labs. READ MORE
