A Comprehensive Guide to Choosing the Right Double Shielded Coax Cable
A Comprehensive Guide to Double Shielded Coax Cable Selection
In today’s interconnected world, high-quality cables are essential for reliable and efficient data transmission. Among the various types of cables available, double shielded coaxial (DSX) cable stands out for its superior performance in demanding applications, making it the preferred choice for data centers, industrial settings, and other mission-critical environments.
Factors to Consider
Choosing the right DSX cable requires careful consideration of several factors:
Cable Construction
DSX cables are designed with two layers of shielding, offering enhanced protection against electromagnetic interference (EMI) and radio frequency interference (RFI). The outer shield is typically made of braided tinned copper, while the inner shield is made of aluminum or copper foil. Cables with higher braid coverage (95% or more) provide better shielding.
Impedance
Impedance refers to the electrical resistance of the cable. The most common impedance for DSX cables is 50 ohms, which matches the impedance of most network devices. However, 75-ohm cables are also available for specific applications, such as video distribution.
Bandwidth
Bandwidth determines the amount of data that can be transmitted through the cable. Modern DSX cables can support bandwidths of up to 600 MHz, enabling high-speed data transfer and demanding applications.
Flexibility
Flexibility is important for easy installation and maintenance. Cables with a high flexibility rating can bend easily without compromising performance, making them suitable for tight spaces and complex routing.
Environmental Considerations
DSX cables are designed to withstand various environmental conditions, such as extreme temperatures, moisture, UV radiation, and chemicals. Choose cables with appropriate ratings to ensure durability and reliability in the specific application environment.
Performance Standards
Various performance standards exist for DSX cables, such as TIA/EIA-568A, TIA/EIA-568B, and ISO/IEC 11801. These standards define the electrical and mechanical properties of the cables, ensuring compliance and interoperability with network devices.
Connector Types
DSX cables are typically terminated with BNC, TNC, or F-type connectors. The choice of connector depends on the equipment and specific requirements of the application.
Choosing the Right Cable
By considering these factors, you can select the double shielded coax cable that meets your specific requirements and ensures reliable, high-performance data transmission in your mission-critical environment.
