Since the first installations of fiber optic networks more than 25 years ago, the goal of the fiber optic industry has been to install fiber optics all the way to the home. From an economic standpoint, fiber was most cost-effective in the long-distance networks. Fiber’s high bandwidth and low attenuation easily offset its higher cost. READ MORE

Every year, fiber optics gains more converts and more market share. And each year, many of its proponents predict the demise of copper wiring. Don't believe it-not yet. The wiring manufacturers have been working overtime for the last 20 years to keep up with the performance of fiber optics, although the latest round of network performance upgrades is severely stretching their capabilities.

In outside plant fiber optic installations, the biggest cause of network failure is what we call “backhoe fade,” which is pretty self-explanatory. Cables in premises installations are unlikely to be dug up accidentally, but are susceptible to damage when installers are working around the cables in trays or conduit. READ MORE

Is it time to fine-tune older fiber? Some fiber optic networks have now been in use for more than 20 years, a tribute to the inherent capabilities of optical fiber. In that same time, copper cabling for premises networks has been through two generations of coax and at least four generations of unshielded twisted pair cabling. READ MORE

Use the Web to keep up with the latest information Most fiber optic installers get started by taking a short class or seminar that covers the basics. That usually means a half-hour lecture each on fiber optic technology, how it is used for networks and the various components. Then, there are short hands-on sessions on cable prep., termination and testing. READ MORE

Signs, sensors and nondestructive testing Most contractors, as installers of building cabling systems and those involved with telephone companies, CATV or utility outside plant installations, are familiar with fiber optics. Fiber optics, however, has other applications besides communications, some of which may be business opportunities for electrical contractors. READ MORE

There’s strength in members Many electricians have their first encounters with fiber optic cabling when asked to install the cable for others who terminate and test it. It usually doesn’t take long for the electrician to realize that he or she is losing a valuable source of revenue, so they too learn how to install fiber optics. READ MORE

Where did these terms come from? Rarely do I present a fiber optic seminar without getting some questions on what some connectors terminology means, and often I’m questioned on how such a term originated. Having been in the business for more than 25 years myself, I do remember some of the origins of these terms and find it amusing to share the stories. READ MORE

Low loss is still a big issue Terminating optical fibers by attaching connectors with epoxy adhesive and polishing the ferrules seems like an anachronism. That was how we started almost 25 years ago, so surely better methods have been developed by now. You can get preterminated cable assemblies that need no field termination at all. READ MORE
