Each of our cables has an upper and lower range of temperature that is suitable for its storage, installation and use. As a result, please refer to our Cable Temperature Range guide for data specific to your product.
The new ampacity table in the upcoming 2017 National Electrical Code is of great benefit for users and installers of premise cables who intend to carry power for the connected devices. The table clarifies and simplifies the process of choosing a cable suitable for carrying such power to devices, making it a simple ‘lookup’ task.
Increased energy efficiency has become a common consideration when developing just about any new electrical product. These technologies include lighting systems, access control, security systems with cameras, computers, access points for wireless networks and more. Where dozens, hundreds or even thousands of powered devices are active at a company site, reducing energy consumption (saving money) is typically a priority.
Thermal management inside medical cables and devices is becoming increasingly challenging for complex, next generation products. The trend for lighter, smaller and more flexible ultrasound probe solutions built with fine wire, ultra-high density coaxial cable is creating new and unique challenges. Many of the conventional approaches with regards to materials and construction are no longer adequate when reliability and usability are paramount.
The goal of this paper is to demonstrate through empirical data that a fully shielded communication infrastructure offers a higher level of performance than similar non-shielded infrastructures. A quality shield design prevents external noise from entering the cable, whether from other cables or from other external noise sources. Outside noise, a growing problem in many infrastructure environments, corrupts data packet transmission and, therefore, can dramatically restrict the network performance.
In order to transmit higher and higher data rates, more complex signal encoding schemes have been developed to more fully utilize the noise and bandwidth properties of Category cables. As the data rates have increased, continued optimization of clock rates and the number of voltage levels has evolved.
A cable shield provides a protective barrier from external electrical fields around the cable. The shield, a conductive metallic foil with a polyester backing, surrounds the cable pairs and helps prevent extraneous voltages from influencing the signal on the pairs beneath the shield layer.
As is well-documented by the Communications Cable and Connectivity Association, and elsewhere in the wire and cable industry, non-compliant, low-quality and counterfeit cables pose a threat to safety, connectivity performance, and installer liability.
Standards organizations are progressing in the development of test requirements and specification limits for Category 8 cabling components for frequencies up to 2 GHz. Previous to Category 8 cabling specifications, the transmission measurement test procedures were based on 2-port Vector Network Analyzers (VNAs) and conventional balun (balancedunbalanced) transformers. These baluns were used to interface the unbalanced ports of the VNA to the differential device under test. Conventional balun transformers use flux linkages to transmit the energy from the input circuit to the output circuit. Conventional baluns with a 1 MHz lower frequency tend to be limited at frequencies above 1 GHz.
You have decided upon a Category 6A infrastructure to support you network needs. You realize that 10 gigabit Ethernet is your application of choice or you grasp that at the rate that throughput demand is growing, not preparing for 10 gigabit Ethernet will significantly hinder future network upgrades. But now, another decision is waiting to be made. Should you go with an unshielded Category 6A solution or a shielded one?
This paper will look at some of the risks associated with the use of unestablished cable brands (a brand virtually unknown to the domestic market), and illegitimate cable.
In network infrastructure, the term open system architecture refers to the practice of using any combination of standards-compliant cable and connective hardware in the design of the network. The standard, ANSI/TIA-568-C, dictates the performance requirements of copper and fiber optic cables as well as the connective hardware for both to ensure that they will accommodate the applications that were designed to operate over them. By employing the open system architecture philosophy, the end user has the freedom to choose the products that best meet their specific needs.
Selecting the appropriate communication cable for a project can be challenging. Whether you are a consultant designing an infrastructure for a major customer or an IT professional who is tasked with turning a large open area into a cubicle farm, choosing the best cable for the project can be daunting.
With the advent of consumer applications that require higher communication data rates (e.g. high definition video), copper cabling technologies that enable these data rates have been forced to evolve rapidly.
Fiber optic cable has become a standard component in most contemporary cable infrastructures. Its immunity to electromagnetic interference (EMI) and radio frequency interference (RFI) make it a desirable cable medium. February 2011
Category 6 Cable was developed to ensure 1000Base-T performance and accommodates other protocols. 1000Base-T, operates over all four wire pairs. January 2008
