Alien crosstalk is the coupling of noise from one cable link to another. This happens if one cable is surrounded by many other cables in a bundle. We identify the cables that surround a cable in a bundle as Disturbers. Cables that can suffer from noise coupling from other cables are identified as the Disturbed cable or (Victim).This becomes more important as we increase the bandwidth requirement of cables for faster applications and the surrounding cables (Disturbers) impact the ability of the disturbed cable (Victim) to transmit data. You might think that using shielded cables i.e. (where there is at least an outer shield) then alien crosstalk would not be a problem. However, if the shield is not terminated correctly even a shielded system can fall foul of alien crosstalk.
Belden’s Digital Electricity Cables are available in copper for power-only applications, and in hybrid copper/fiber constructions to transmit power and data over long distances in a single cable run.
The transmit up to 20 times more power or 20 times more distance than PoE: up to 2,000W or up to 2km reach in indoor and outdoor applications. Digital Electricity Cables support Internet of Things (IoT) and convergence in venues such as airport terminals, convention centers, hospitals, high-rise hotels, stadiums and office towers.
Siemon has launched the PowerGUARD brand of twisted-pair copper cabling products, which is specifically designed to provide superior support for remote powering applications such as Power over Ethernet (PoE) and Power over HDBase-T (PoH).
Protecting network traffic from the noise and heat inherent with PoE is critically important. Download Berk-Tek’s white paper for an overview of the real-world challenges that are taxing copper-based cabling systems as IP convergence becomes more prevalent.
While standard twisted pair technology has improved, over time, gaps within pairs will inevitably develop. Download this free white paper to learn more about Belden’s innovative design to the twisted and bonded pair cable, which ensures you never have to deal with noise interference in your industrial cables, as well as how to accurately specify the right cable for your industrial environment.
Available in UTP and shielded, Siemon’s Z-MAX Category 6A System features the highest performance margins across all critical transmission parameters, the fastest, easiest and most reliable termination process, superior transmission consistency and customer focused usability, efficiency and ergonomics. End-to-end Z-MAX Category 6A UTP and shielded systems include Category 6A cable, outlets, modular cords, patch panels, trunking cable assemblies, work area solutions and the Z-PLUG™ field terminated plug.
Harsh environments require an IT network that will rise to the challenge. Siemon Ruggedized Infrastructure Solutions protect critical network connections from dust, moisture, industrial cleaning chemicals and vibration. Ruggedized infrastructure solutions are ideal for protecting valuable connections in laboratories, hospitals, food processing plants and other harsh environments.
Wi-Fi 6 WAPs will need more power and thermally stable shielded cabling systems. Learn about other considerations as you prepare for the new wave of wi-fi.
The Telecommunications Industry Association’s (TIA) TR-42 Telecommunications Cabling Systems Engineering Committee is perpetually developing and refining standards documents to guide the specification, design, installation and administration of cabling and related communications systems. TR-42’s most recent meeting took place June 9-13. Based on subcommittee-meeting minutes and other reports, here is a rundown of some of the current and recent activity from TR-42.
Establishing a group for Women in BICSI was a dream I nurtured for many years. This dream finally gained traction in 2014 when a core group of women met to establish a format to encourage women in the industry to gather together to share their experiences. Since then we’ve had annual meetings and networking sessions, established a LinkedIn page, developed a page on the BICSI website and sponsored a female candidate to the BICSI Cabling Skills Challenge for the past five years.
