Who Doesn't Hate Attenuation?

UPDATE 3/18/10: Read Corning's new press release announcing ClearCurve.

Attenuation Ruins Everything

It's a warm summer day and you're watering your front yard. The water is flowing steadily and your lawn looks like something the Greenskeeper at Augusta National would be proud of. Without warning, the once powerful flow of water is reduced to a trickle. Confused, you look over your shoulder to see your neighbor's son --the little punk-- has bent your garden hose in two and is smiling at you menacingly. This is attenuation in a nutshell.

Just like water through a hose, light running through fiber optic cable is susceptible to bends and pinches. These bends and pinches affect the transmission of valuable data across the fiber. Whether it's in the office or in the data center environment, attenuation is always costly. In the face of skyrocketing bandwidth demands: fiber is the future. But… attenuation has the ability to completely undermine your once lightning fast fiber network and endanger your investment.

Whether it's accidental bends, fiber patchcords closed in cabinet doors, or simply trying to cram too much into a small space, the signal loss can be substantial.

ClearCurve Multimode Fiber Steps In 

While many solutions exist which improve bend performance, Corning Cable Systems "selected an engineered optical trench technology for the new ClearCurve multimode fiber". As you'll learn from reading the attached white paper, ClearCurve's design secures the modes in the core of the fiber, resulting in less signal loss.

To demonstrate just how effectively ClearCurve reduces attenuation, Corning conducted a series of tests and published their results in the attached PDF entitled: LANscape Solutions with ClearCruve Multimode Fiber. All of the tests and results are worth reading, but I want to share one in particular that caught my eye.

Look at the differences in attenuation! That's a difference of 4.85 dB: amazing. To learn more about Corning Cable System's ClearCurve multimode fiber and to see more test results download the PDF here.
