A city manager called the Fiber Optics Association for advice regarding a fiber optic network his organization was planning. They were developing the scope of work and a request for proposal on a fiber optic network that...

Sometimes the simple things get ignored, or lost, or forgotten. With all the technical questions we get at the Fiber Optics Association, we are often reminded that these details are sometimes very important and are worthy of...

My February column covers the reasons for power and loss budgets and how to interpret them. In this article, I’ll show you how to calculate loss budgets properly. Remember the differences: a power budget gives you the range...

When you design and build a fiber optic network, the goal is to have it work properly with the communications networks you need. Communications networks generally specify only two parameters for the cable plant: the type of...

In my January 2020 fiber optic update, I wrote, “But later in the year [2019], it seemed that disruption was being disrupted.” Well, 2020 did not wait until later in the year; disruption began in full force by early March...

Around the world, hundreds of millions of homes and businesses are connected to the internet on optical fiber, and almost every one with a network architecture called passive optical network (PON). There are two main...

When I first started working in fiber optics 40-plus years ago, the world was quite different. Computers were big rooms full of cabinets used by businesses and monitors had cathode-ray tubes, just like the televisions back...

Last month I wrote about a change in fiber optic standards that seemed out of step with the technical community. That raised questions such as how do fiber optic standards get written? And what are standards anyway...

Recently I was swamped with almost a dozen proposed updates to Telecommunications Industry Association (TIA) standards to vote on and review. In fiber optic technology, most standards deal with the specification and testing...

Around the year 2000, there was a battle royale between fiber and copper cabling forces to capture the desktop. For more than a decade, unshielded twisted-pair copper—what many of us still call Cat 5—had ruled the local area...

Do you live on a dirt road? I doubt it. Most of us live on paved streets off wide avenues and not too far from an expressway that connects us to the far corners of the country. If you have to drive down a dirt road to get...

Let’s face it, the term “smart” is getting worn out from overuse. Smart cars, smart grid, smart buildings and many more similar terms have diminished the meaning. In most cases, what it really means is bringing whatever it...
