Recently we have been getting questions about how to determine if an SFP is working. I’m going to use SFP generically here to represent a multitude of the various optical modules that are available. The Fluke Networks fiber testers can be used to measure the light that is being put out by and SFP.

By now you’ve probably heard of 8-fiber MPO plug and play solutions available on the market, which are ideal for Gigabit (40GBASE-SR4) and 100 Gigabit (100GBASE-SR4) applications that use 8 fibers with 4 transmitting and 4 receiving at either 10 or 25 Gb/s.

We’ve just posted Version 5.1 Build 4 of the Versiv software for the following products:

Maybe you’ve seen TCL and ELTCTL listed on your cable spec sheet, or perhaps you’ve noticed them on your DSX CableAnalyzer, and you’re simply not familiar with these parameters, what they indicate and if they are required. Let’s take a closer look.

What is Mode Conversion?

But dirt happens. And while cleaning may not be a barrel of fun, there is always some sense of satisfaction when it’s done and everything is looking its best.

By now you probably know that Category 8 cabling was approved by the TIA TR-42.7 Copper Cabling Subcommittee, and maybe you've even heard that Fluke Networks introduced the DSX-8000 CableAnalyzer, the first field tester independently verified and endorsed to meet all of the requirements for the Cat 8 field testing standard.

 You have likely heard copper network cabling referred to as balanced twisted-pair copper cabling, and maybe you’ve heard of the testing parameter referred to as DC resistance unbalance. But what does all this balance-related terminology really mean, and why should you care?

OM5, previously known as wide band multimode fiber or WB MMF, has been quite the hot-button topic as the standards have been widely debated and are now finally concrete.

So what is OM5 exactly? Most simply, it’s a version of the OM4 fiber with additional bandwidth characterization at 953 nm.
