In several recent columns, I discussed the process of fiber optic terminations. I examined each step in detail and shared some of the things I have learned from experience and teaching students. As they say, one learns from one’s mistakes.

We left off last month preparing a fiber optic cable for termination. We were at the point where we had slipped the strain-relief boot and crimp sleeve over the cable jacket if we were using a simplex cable and sorted out the tight buffer fiber we were going to terminate out of a distribution cable.

Last month, I addressed how to determine if an adhesive/polish connector was good by inspecting the polished end of the connector with a microscope. If the polished end of the connector ferrule looks smooth and does not have scratches or cracks, it’s highly likely the connector has been properly made and will be low-loss.

Since fiber optics is growing in market share for all kinds of applications, 
I am hearing more stories about problems with installations. At The Fiber Optic Association, I handle most of the technical inquiries, so I tend to see the trends develop. READ MORE

As with any project, a communications cabling project requires comprehensive management. Project management for cabling or related networks is best understood when broken into five subtopics:
 Planning, Design, Installation, Testing and Operation. These five areas are equally important and interrelated because the success of each stage depends on proper execution of the preceding one.

Optical local area networks (OLANs) have been the subject of these columns for several months, and before that I discussed networks. This month’s column ties together some loose ends to help you understand the OLAN concept better. It should also help you explain it to your customers, so they understand the differences and advantages of OLANs.

Optical local area networks (OLAN) will cause you to rethink practically everything you have learned about LANs and LAN cabling. Of course, any major change in technology like this causes FUD (fear, uncertainty and doubt), just like voice-over Internet protocol (VoIP) and Wi-Fi have already.

A life-threatening event 
occurs at a large building where many people could be in danger. In this case, it is a smoky fire, but it could also be an earthquake or a mass shooting. The fire alarm system senses the fire, locates the problem, and immediately begins sending signals. It informs the local fire station. READ MORE

Last month, I covered the challenges to traditional structured cabling from multimode optical fiber and wireless. Multimode fiber became the favorite cabling for the backbone but never made it to the desktop because every connected device already had a free Cat 5 port. READ MORE
