When it comes to testing a cabling installation, there are essentially three choices--verification, qualification and certification.
While some features overlap between test tools as you move up the hierarchical ladder from verification to certification, each type of testing answers one of the following questions to help you make the right choice.
Over the past decade, we have seen significant advancements in the capabilities of fiber optic cabling--from expanded distances to speeds reaching 40 and 100 Gig.
While fiber loss requirements are getting tighter, efforts are also underway to increase fiber bandwidth carrying capacity with reduced fiber counts--all while following the roadmap to 400 Gig.
The Count Down
While the smart people who install, test and certify network cabling plants know the importance of meeting standards performance parameters and ensuring application support, even the best of us can make mistakes that adversely impact the bottom line and customer satisfaction.
With the need for increased speed and power over Ethernet (PoE) being addressed within IEEE standards, work within TIA must follow suit as the two standards bodies work hand in hand to ensure that the applications put forth by IEEE can be adequately supported by the cabling infrastructure.
Let's take a look at some of the recent and most significant standards activity within the Subcommittee and how they relate to standards development happening within IEEE.
We repeatedly try to drive home the need to keep your tester up to date with the latest firmware, and for good reason. Not only do we want to make sure you don't miss out on the latest features that can help you test faster and more accurately, but as standards change, so must your tester.
Bi-directional testing of fiber links for Tier 2 (OTDR) testing is not only required by industry standards and most manufacturers for warranty, it's also the only way to know the actual overall loss for a link. That's because measuring the loss of fiber connectors and splices, as well as overall link loss, depends on the test direction. Testing a fiber link in one direction can give you different results then testing the same fiber link in the opposite direction.
It’s late afternoon and your team has just finished a job. Now it’s time to gather up the testers and head back to the office with the results. But if that's your white box truck back there sitting in miles of traffic, how much will it cost you?
The performance of an installed optical fiber link hinges on the condition of the connector end faces. Test suppliers have been pushing end face inspection for good reason – most service calls are due to problems with connectors. Standards bodies are busy making improvements to their documents on visual inspection. This work is being done in subcommittee 25 working group 3, the working group responsible for developing standards for customer premises cabling. Recent developments on end face inspection is the topic of this blog.
