Contaminated connections remain the number one cause of fiber related problems and test failures in data centers, campus and other enterprise or telecom networking environments.

Since the development of 40GBASE-T (IEEE 802.3bq) began a few years ago, most of us believed that the next Ethernet data center speed for twisted-pair copper cabling beyond 10 Gb/s would be 40 Gb/s.

How long are the fiber links you need to test? Is it a short 50-meter multimode data center link, a longer 550-meter backbone, or maybe even a 130-kilometer singlemode link?
With contaminated connections remaining the number one cause of insertion loss and back reflection that inhibits optical transmission and causes havoc with expensive transceivers, it’s vital that fiber end-faces at both ends of a link are visually inspected.

You’ve just finished a copper cabling installation for a customer, your DSX-5000 CableAnalyzer is properly configured and you’re ready to start testing. With a press of the “TEST” button, you’re off and running.
Link after link, the tester displays a “Pass” and you’re feeling really good about the quality workmanship of your installation.

Last week at the opening of the BICSI Conference in Las Vegas, the editors of Cabling Business Magazine announced that Versiv and LinkWare Live have each won the Cabling Installation and Maintenance Innovator’s Award. These awards recognize the most innovative projects and products in the structured cabling industry. The judging panel consisted of cabling and communications system specifiers, designers, integrators and managers with vast professional experience.

Testing structured fiber cabling to international standards such as ISO/IEC 14763-3 has been defined. In the last few years, the question of loss (attenuation) measurement uncertainty has been raised. Since 14763-3 specifies test limits, the user of the standard may need to know the amount of uncertainty in the measurement. Experts from IEC, well-versed in fiber metrology and uncertainty calculations, were requested to provide simplified guidelines, a table of sorts, that a user such as an installer might find useful.

In February, we pondered whether 2015 would be the year of the drones:
Six months later, the answer appears to be a resounding “yes.” Near-miss encounters between commercial aircraft and remote-controlled drones continue to make headlines at an alarming rate.

The Telecommunications Industry Association (TIA) is committed, by formal consensus, to develop standards for the benefit of industry and is represented by hundreds of companies. While participating companies cooperate to develop standards, each have their commercial business interests to protect. Sometimes, these companies over-reach to meet their business goals. Fortunately, the TIA voting and balloting process works well as a means to check and balance sometimes rogue proposals.
