Akin to water flowing from a small pipe into a large pipe, gainers are essentially perceived increases in optical power that occur at splice points due to variations in fiber characteristics, including core diameter, numerical apertures, mode field diameters and backscatter coefficients.

The use of plug-and-play 12-fiber MPO solutions for multimode fiber backbones in the data center has been popular for several years, starting with 10 Gigabit Ethernet where 12-fiber MPO assemblies connect MPO-to-LC cassettes or modules that transition the 12-fiber MPO connections to 6 duplex LC connections.

Over the past decade, the amount of fiber in the data center has increased significantly due to the need for higher bandwidth between switches and the ever increasing amount of equipment requiring fiber uplinks to storage area networks (SANs), not to mention the demand for maximum availability that calls for redundant primary and secondary fiber network connections to every piece of equipment.

The TIA TR-42.7 Copper Cabling Subcommittee recently approved specifications for Category 8 cabling (TIA 568 C.2-1), the latest twisted-pair copper system designed to support future IEEE 25GBASE T and 40GBASE T applications currently under development.

With all the buzz surrounding Category 8, you and your customers might be wondering how exactly it will impact the deployment and testing of cabling infrastructures.

Let's take a closer look at where it will be deployed and some of the key characteristics that impact installation and testing.

If you're at all familiar with copper cable, you've probably heard about crosstalk--the phenomenon by which a signal transmitted on one pair or one channel creates an undesired affect on another pair or channel.

Just Now Upgrading to 10 Gig? We Didn't Forget About You

While upgrading backbone cable plants in the LAN to support 10 Gig has been going on for several years since the release of the 10GBASE-SR standard for fiber, many enterprise businesses did not previously require these types of speeds, until now.

Getting the right setup to ensure the best test results with your DSX-5000

If you turn up to a new installation with your new DSX-5000 then it might be up to you to ensure the DSX-5000 is set up correctly. So what do you have to do?

Well, if it’s brand new out of the box, then you need to do a basic set up. But, with every new project there may need to be changes if you make installations tests in other countries or time zones with different requirements for date or time differences, or different formats for them or numbers.

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."
