One of the first customer visits I made after starting a company making fiber optic test equipment was in the basement of a government building in Washington, D.C. I brought along one of our test kits for demonstration, with...

For the last couple of columns, I’ve focused on learning new things and techniques. Last month, I wrote about high fiber count cables—1,728, 3,456 and 6,912 fibers—and the need to use ribbon or mass fusion splicing with them....

Last month, I wrote about how a newcomer could get started in fiber optics and learn the basics. What if you are already experienced in fiber optics and want to keep up with new technology? I can empathize with you. I have...

My last two web exclusive articles ( part 1 and part 2 ) have covered how optical time domain reflectometers (OTDR) work and make measurements. Now let’s get into several ways they try to confuse you. Have you heard of...

To get started in fiber optics, you need to follow a simple path. First, if you are looking at it as a new career, you must research the available jobs and determine what is expected of a worker in that field. If you are...

It seems you can’t pick up a newspaper today without seeing an advertisement touting a cellular company’s coming 5G wireless network. Some ads claim the service provider offers 5G connections to the home and you should sign...

In my previous article about OTDRs , I covered the basics of how the instrument works and how it is used to make basic measurements of attenuation, splice or connector loss and reflectance. If you need to, go back and review...

It’s always nice to hear from my readers. In December 2018, I wrote about aerial fiber optic cables, and that column prompted a very interesting inquiry. Usually these inquiries are technical in nature and come from...

Recently, I attended a meeting for local residents on my city’s plans to allow numerous “small cell” cellular sites around the city. The city’s website showed more than 600 potential sites, all on city-owned street lights. No...

The most powerful—and complicated—instrument used for fiber optic testing is an optical time domain reflectometer (OTDR). In the hands of an educated tech, the OTDR is a powerful testing and troubleshooting tool, but it can...

It’s human nature to be more vocal when complaining than complimenting. That means I hear a lot more about what goes wrong than what goes right. I retell these stories because you should learn from your (and others’) mistakes...

I’ve been doing a fiber update for ELECTRICAL CONTRACTOR every January for 16 years. I enjoy sitting back and taking an overview of the current fiber optic technology and markets, distilling it down to what I see as the most...
