Wondering about standards compliance and testing requirements for extended-length twisted pair cabling? Sometimes there is pressure to connect a device beyond the guidance of the cabling standards. In an extended-reach channel, the installation will not be standards compliant. This may mean that the application support will be limited to certain data rates, certain cables and components, certain installation conditions, or is tied to certain types of network equipment. It could mean that the application support is not assured by the network equipment manufacturer, and instead falls to the cabling vendor. That might be just fine with your customer, but it’s best to make sure. You should educate them about the solution and the implications of non-standards compliant cabling. And just because something isn’t standards compliant, doesn’t mean you don’t have to test it.
FFor the third year, Fluke Networks has teamed up with Cabling Installation and Maintenance to survey network and structured cabling professionals about salaries and jobs. This survey gathered data on the areas that impact salary, like education and experience. We also asked about types of jobs, bonuses, job changes, and how COVID-19 impacted the workforce. In addition, this survey includes information on salary by job titles like network technician salary, network engineer salary, cabling general management salary, and network designer or architect salary. There are some significant and surprising departures from findings of prior years.
Equipment cords are an integral part of any network—whether it’s a fiber jumper used to make connections between fiber patching areas and switches in the data center or a copper patch cord out in the LAN to connect end devices to the work area outlet. Unfortunately, they are also typically the weakest link in the network. They are handled and manipulated more than any other component, which makes them more subject to damage. They are also often considered a commodity item and some end users will seek to save money by purchasing them from lesser-known generic sources that may skimp on quality and compliance.
Like your car’s oil can wear out over time and become less effective at properly lubricating the engine, tester components can deviate from their original behavior. Part of the process of designing an accurate tester is determining what the appropriate calibration interval should be. Fluke reviews specifications as well as looking at real world experience with the thousands of testers in use. As with any electronic, resistors, capacitors and circuits can drift over time due to temperature, humidity and warming up and cooling down every time you turn your tester on and off. The circuit boards within the tester can also be contaminated by dust or other materials.
Testing with both an OTDR and an OLTS is referred to as “Tier 2” testing within TIA standards and “extended” testing within ISO standards. Find out how OLTS and OTDR testers work, when to use them and how they complement each other when it comes to ensuring the performance of today’s fiber optic links in this free guide from Fluke Networks.

Most people who do an OTDR measurement, do it using just a launch fiber. The advantage in doing it that way is you don’t have to have someone at the other end to move the tail fiber across the patch panel.
Despite causing a bit of controversy in the industry since they were not originally recognized within ANSI/TIA cabling standards that require twisted-pair structured cabling to consist of 22 AWG to 26 AWG cables, these skinny patch cords continued to grow in popularity.
When testing, you will encounter different applications, cabling and connectivity in different functional areas of a data center. This blog post will help you understand each functional area and what you will likely need to test in each.
The demands being placed on our data centers are larger than ever. This is true for all types and sizes of data centers, from the largest Hyperscale, to Private, and even Edge. This webinar will address advancements in Single and Multimode fiber and how they are being used in data centers. This presentation will look at the latest applications and the requirements for fiber to support them. After that, we will look at testing these fibers, calculating a loss budget for current and future applications, and how you can increase confidence in the test results. At the end of this presentation, you will understand how improvements in fiber construction allow communications at multiple wavelengths are helping to reach speeds in excess of 400G as well as what testing will assure that the fiber has been properly installed.
Fluke Networks and Planet Associates have integrated Fluke Networks’ LinkWare Live and Planet Associates’ PlanetIRM, which is a next-generation cloud-based infrastructure configuration management software platform. LinkWare Live is Fluke Networks’ cloud-connected online cable certification solution. The companies explain the result of this integration is “a single solution that can design, consolidate, aggregate and visualize an organization’s facilities, IT/telecom, inside-plant, outside-plant, circuits, network assets and connectivity data.”
