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.
Through the input of more than 60 leading commercial real estate, asset management, technology and ICT industry leaders, the Telecommunications Industry Association (TIA) in conjunction with UL, the leading global safety science company, has defined six criteria that form the basis of the SPIRE™ Smart Building Program for assessing and rating smart buildings. None of these criteria alone make a building smart, but they work together in harmony to provide a complete, balanced assessment methodology that considers the modern-day challenges that come with the increasingly digital world we live in today.
As internet traffic, connected devices, and cloud-based services proliferate, there is a corresponding increase in the deployment of optical fiber. This article highlights the key market segments and technology enablers driving demand and then discusses the ways that optical fiber technology is being deployed to meet the demands for higher bandwidth, low latency networks.
Facilitating POLs over Existing Multimode Fiber Cabling Infrastructures with MPLC-enabled Technology
To meet the growing demand for high-speed and higher bandwidth, many companies believe they need to deploy single mode fiber. Since approximately 78% of optical fiber deployed in LANs is multimode, this would require an expensive upgrade. However, MPLC-enabled technology such as modal splitters, can make POL singlemode equipment compatible with MMF cabling.
To meet exploding network bandwidth demand, 50 Gb/s and 100 Gb/s signaling lanes in server (and fiber to machine) and switch links, have emerged requiring higher speed standards. Ethernet and Fibre Channel have both either recently published (for 50 Gb/s per lane) or are developing (for 100 Gb/s per lane) new low cost, short reach standards that will utilize these lane rates, for both serial and parallel solutions. This presentation will provide an update on those standards efforts, along with the underlying market, industry, and technology trends.
TR-42.7 Engineering Committee on Telecommunications Copper Cabling Systems (568) on Mar. 24 issued a call for interest for document TIA-1152-A, initially titled “Requirements for Field Test Instruments and Measurements for Balanced Twisted-Pair Cabling.”
Per a TIA statement, TR-42.7 is developing guidelines in the area defined by the following scope: “Revise ANSI/TIA-1152-2009 as determined in TIA TR-42.7, incorporating new specifications and other information as required to support field testing of cabling described in ANSI/TIA-568-C.2-1.”
Per TIA, stakeholders for the project may include, but are not limited to: field tester manufacturers; test equipment manufacturers; structured cabling products manufacturers; and structured cabling installers.
The revolutionary transmission technology Single Pair Ethernet is crossing the threshold from idea to market maturity. SPE could well replace traditional field bus technology in many areas. It is coming at just the right time to accelerate the digitalization of building automation and the growth of the Internet of Things (IoT).
IO-Link and Single Pair Ethernet, two recent networking protocols for improved industrial connectivity
single-pair Ethernet takes the enterprise-class networking protocol and implements robust and reliable device communication over a single twisted pair. Reducing the number of pairs by a quarter reduces cable weight, reduces cable cost, and uses robust industrial-grade widely available connectors. Unlike the serial-based IO-Link, SPE functions as a standard networking protocol and can operate over distances of up to 15 metres using unshielded cables and 40 metres using shielded cables.
This white paper from CommScope covers how to create an integrated suite of connectivity solutions; without adding layers of complexity; understand where and how key technologies such as PoE, IoT, Wireless, etc. fit.; how to flatten complexity with shared infrastructure; how to wire for the future, not just the present; the ins and outs of adding wireless connectivity.
Cabling Installation & Maintenance recently asked Carol Everett Oliver, RCDD, ESS, DCDC, and BICSI President Elect, to weigh in on hot topics in the information and communications technology (ICT) sphere.
