I spend most of my time with fiber optics, but I have quite a bit of experience with copper cabling too. Fiber is always in the news, and wireless threatens to take over all communications; copper has been quiet and has not...

Dirty connectors are major problems in fiber optics. They cause high connector loss and high reflectance, and they contaminate transceivers. Network operators claim the majority of fiber optic network problems can be traced...

For the last few columns, I’ve focused on fiber optic cables, their types, installation techniques, etc. With that background, I want to cover some additional details you need to know to design and install a fiber optic cable...

Every technology has its own jargon, of course. Some of it we joke about because it’s mostly TLAs—the abbreviation for “three letter abbreviation,” the favorite way tech people have of showing how cool they are. I remember a...

Recently, the Fiber Optic Association (FOA) has worked with and, at times, even trained city planners and traffic engineers. After talking to people responsible for municipal networks, it’s clear why they are so harried. They...

In a perfect world, before designing or installing an underground fiber optic network, you phone the Call-Before-You-Dig number, 811, and get a file (or a set of paper drawings, if you are old-school) that would include...

The fiber optic industry really began taking off about 30 years ago. Fiber’s bandwidth and distance superiority over copper wires or radio links—and the financial advantages those technical advantages provided—prompted a...

Last time, I wrote about what you can learn from keeping your eyes open, and I continue on that theme this month. This time, we’re looking up and discussing aerial fiber optic cable. Some years ago, in the Fiber Optics...

Last month, I wrote about a new class of fiber optic cables called microcables, which, as the name implies, are much smaller than regular fiber optic cables. They fit into much smaller ducts and even allow a unique...

Microcables are becoming very popular, and it’s important to understand their purpose, applications and installation. These smaller fiber optic cables are designed for applications where large numbers of fibers are required...

I like to walk. Always have. It's low-impact, highly effective exercise that keeps you healthy and, if you keep your eyes open, helps you learn about what's happening in the world around you. Of course, I live in an area that...

While we have only a few types of optical fiber, we have hundreds of types of fiber optic cable. That’s because cable is designed to protect the fibers in the environment in which it is going to be installed and in the method...
