TIA probing field test instrument requirements for balanced twisted-pair cabling

By on • ( Leave a comment )

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.

Single Pair Ethernet Now Ready to Use

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.

Leveraging Single Pair Ethernet In Building Automation

There are numerous efforts to take Ethernet to the edge devices but network fragmentation has resulted in multiple communication networks coexisting in building automation – heating, ventilation and air-conditioning (HVAC) applications use Modbus, access control uses BACnet, lighting uses LonWorks and fire safety uses Ethernet. Single Pair Ethernet offers a simplified solution that could support all these devices and offer direct accessibility for the control system, status updates, predictive maintenance, standardized hardware and interoperability across various systems.

Is IO-Link with Single Pair Ethernet the Future?

20 meters. That is the maximum distance between an IO-Link master port and an IO-Link device using a standard prox cable. By using SPE, we gain the Ethernet cable length advantage. So, instead of being limited to 20 meters, your IO-Link cabling could stretch to 100 meters! Imagine the opportunities that opens in industrial applications. It is possible that even longer runs will be achievable.

2021 – The year of the Smart Building

While the workplace will be for ever changed, it is not a matter of “if” but “when” and “how” we will return to “in-person” collaboration. Returning trust to the workplace will take effort. This is where the “smarts” of a smart building comes into play. The same data used to reduce cost by reducing energy use can be further refined beyond just general occupancy to detect density allowing HVAC systems to adjust airflow, humidity, and temperature.
