It felt like a Monday morning when the call, actually an e-mail, came in. “I think my DSX is broken!” As you know, they are really tough machines and, when it looks like the Fluke is wrong, usually it isn’t. “What makes you think it is broken?” I...
Verification of test reference cords is easy, right? Yes, usually…but not always. After the power meter is set to 0 dB via the reference procedure, the loss of a mated connector pair is expected to be less than 0.20 dB for single-mode (e.g., -0.20...
Depending in which functional area of the data center you are testing, there are different applications, cabling and connectivity that you will encounter. Understanding the functional areas of the data center and what you will likely need to test in...
The latest TIA standard for balanced twisted-pair cable systems – TIA 568.2-D – was approved for publication during the TR-42.7 meeting on June 12, 2018. It will replace TIA-568-C.2 and is expected to be published in the coming weeks. For the past...
If you are familiar with deployments where a horizontal cable run terminated on one end to an RJ-45 plug connects directly into a device, then you are familiar with what is now referred to as a Modular Plug Terminated Link, or MPTL (even if it...
While many of our blog readers are well versed in designing, installing and testing cabling systems, some of you may be new to the industry and still trying to make sense of the various performance parameters, standards and testing requirements that...
Over the past few years, several manufacturers have released 28 AWG patch cords that offer a smaller diameter to help improve airflow around active equipment and ease cable management at high density patching areas due to reduced congestion and a...
When it comes to calculating loss budget, it’s important to know the loss limits for the given application as specified by industry standards. But if I really want to know how to design a system to these limits, you also need to know the loss of the...
To some, it may seem like just yesterday that Fluke Networks introduced the Versiv™ family of Cabling Certification Testers , especially for those who are still hanging on to their discontinued DTX CableAnalyzer™ (don’t forget that all service and...
While labeling per the ANSI/TIA-606-B Administration Standards is considered best practice, let’s face it—labels don’t always happen or sometimes they’re simply not visible where you need them. Over time, cabling links may also have been...
