Fly safe this summer

Lisa Phifer

It’s that time of year when so many of us jet away on summer holiday. But, as the availability of in-flight Wi-Fi grows, so does the potential for mid-air wireless attacks.

According to RouteHappy, flyers now have at least some chance of getting in-flight Wi-Fi on 24 percent of flights worldwide. Within the US, that likelihood spikes to 66 percent – including all of Virgin America and over half of Delta, JetBlue, and Southwest flights. Want to increase your odds of getting online aloft? Choose a flight served by Boeing equipment.

It’s Not You. It’s Your Tester

Robin Rees

When it comes to testing your multimode optical fiber installation, inconsistent results can leave you confused and wondering if you are within your loss budget. And with today’s higher speed fiber links that require even tighter loss budgets, accuracy is more critical than ever.

But it doesn’t have to be this way. The launch condition of the light source you’re using to test has the greatest influence on your loss measurements. In other words, the wrong launch condition means the wrong measurements.

What you need is a properly controlled launch that is consistent and accurate—neither overfilled nor underfilled. Overfilled may leave you thinking you’ve gone over budget, while underfilled may leave you thinking you have room for more loss when—in fact—you do not.
