Кабельные хроники


Когда дело касается тестирования установки кабельных систем, существует три варианта: проверка, квалификация и сертификация.

Хотя некоторые функции инструментов тестирования совпадают при движении по иерархической лестнице от проверки к сертификации, каждый тип тестирования отвечает на следующие вопросы, что помогает сделать правильный выбор.


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.


Двунаправленное тестирование оптоволоконных линий для сертификации уровня 2 (OTDR) не только заложено в отраслевых стандартах, но и требуется для сохранения гарантии большинства производителей. Это также единственный способ узнать фактические общие потери канала. Это связано с тем, что измерение потерь разъемов и соединений оптоволокна, а также общих потерь канала зависит от направления. Testing a fiber link in one direction can give you different results then testing the same fiber link in the opposite direction.  


Предположим, что сейчас вечер, и ваша команда только что закончила работу. 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.
