Testes de cabo 101: There's No Gain with "Gainers"

In a recent Cable Testing 101 series blog on mixing multimode fiber types, we covered the considerations surrounding mixing legacy 62,5 micron (µm) OM1 fiber with today's laser optimized 50µm OM3 and OM4 fiber and highlighted the "gainers" that can happen when transmitting from a smaller 50µm fiber core to a larger 62,5µm fiber core.

Testes de cabo 101: Measuring Insertion Loss for Fiber and Copper

The amount of energy that a signal loses as it travels along a cable link used to be referred to as attenuation--the verb attenuate being defined by Merriam Webster as "to reduce the force, effect or value of something."

How to Measure the Loss in the APC Connector?

This question often gets asked in my classes at the same time as when talking about launch methods using launch and tail fibers. So let’s talk about launch fiber compensation.

Understanding POH: The Power Behind HDBaseT Technology

 Last month we posted a blog about HDBaseT that explained the application and how testing isn't really any different since standards-based Category 5e, 5 or 6A will support it. But maybe you've also heard about power over HDBaseT, or POH, and you're wondering how that differs from power over Ethernet (PoE).

All About Alien Crosstalk Measurement

Alien crosstalk is a relatively new measurement that’s widely misunderstood. I’m often asked why it’s an important measurement and if it’s required to be measured by the standards. Also misunderstood is the sampling criteria for alien crosstalk measurements, which are applied so that not all links have to be tested?

Novo aplicativo para agilizar a rotulagem de cabos - iLink&Label

Embora seja, provavelmente, uma das normas menos faladas, e que muitas vezes é considerada voluntária, a norma de rotulagem TIA-606-B existe por um motivo.

Uma infraestrutura sem rótulos resulta em uma desordem incontrolável que, no final das contas, torna todas as tarefas de reconfiguração e solução de problemas em um jogo de esconde-esconde demorado, frustrante e de rastreamento dispendioso.
