Construction and Design Features of Cat 7e Ethernet Cables

Cat 7e Ethernet cables are designed to transmit data over long distances with minimal loss and interference. They are commonly used in high-performance networks, such as those found in data centers and enterprise environments. This article will provide an overview of the construction and design features of Cat 7e Ethernet cables.

Cables Structure

Cat 7e Ethernet cables consist of four twisted pairs of stranded copper conductors. Each pair is wrapped in an individual foil shield, which helps to reduce crosstalk and electromagnetic interference (EMI). The four pairs are then wrapped in an overall shield, which provides additional protection from external sources of interference.

Conductors

The conductors in Cat 7e Ethernet cables are made of stranded copper. This type of copper is used because it is more flexible and resistant to breakage than solid copper. The stranding also helps to reduce skin effect, which is a phenomenon that can cause data loss at high frequencies.

Insulation

The conductors in Cat 7e Ethernet cables are insulated with polyethylene (PE). PE is a type of plastic that is known for its high dielectric strength and low loss. It is also resistant to moisture and heat, which makes it ideal for use in harsh environments.

Shielding

Cat 7e Ethernet cables are shielded with both individual foil shields and an overall shield. The individual foil shields help to reduce crosstalk between the pairs. The overall shield helps to protect the cable from EMI and other external sources of interference.

Category Rating

Cat 7e Ethernet cables are rated for use in high-performance networks. They are capable of transmitting data at speeds of up to 40 Gbps over distances of up to 100 meters. They also meet all of the requirements for ANSI/TIA-568-C.2, which is the standard for structured cabling systems.

Applications

Cat 7e Ethernet cables are used in a variety of applications, including:

Data centers

Enterprise networks

High-performance computing (HPC) environments

Industrial automation

Medical imaging

Summary

Cat 7e Ethernet cables are designed to provide high-performance networking over long distances. They are constructed with high-quality materials and are shielded to protect them from interference. Cat 7e Ethernet cables are ideal for use in data centers, enterprise networks, and other high-performance applications.
