What is the CAT7 Jumpers' construction and material used for the conductors and shielding?

2023-10-17

The construction and materials used for the conductors and shielding in CAT7 jumper cables are designed to meet the high-performance requirements of CAT7 Ethernet standards. Here are the typical construction and materials used:

1. Conductors: CAT7 cables typically use copper conductors for transmitting data signals. CAT7 cables are generally available in two variations: shielded twisted pair (STP) and fully shielded twisted pair (S/FTP). Both types of cables have individual pairs of twisted copper conductors, with each pair having its own shielding.

2. Shielding: CAT7 cables are known for their extensive shielding to minimize electromagnetic interference (EMI) and crosstalk between the twisted pairs. In STP cables, each twisted pair is individually shielded with a metallic foil, and an overall braid or foil shield covers all the pairs together. S/FTP cables, on the other hand, have additional overall shielding over the individual pairs, enhancing the cable's resistance to interference.

3. Insulation: Each twisted pair of copper conductors is insulated to prevent electrical contact between them. The insulation material used is typically made of a high-quality, low-loss material that meets the CAT7 specifications.

4. Jacket: The outer layer of the CAT7 jumper cable is covered by a durable jacket. The jacket material can be made from PVC (Polyvinyl Chloride) or LSZH (Low Smoke Zero Halogen) for safety in case of fire. The jacket protects the internal components of the cable from physical damage and environmental factors.

The extensive shielding in CAT7 cables makes them ideal for high-speed data transmission and applications that require minimal interference and high reliability. The construction materials used ensure that the cable meets or exceeds the stringent specifications set forth for CAT7 standards.

It's important to note that the specific construction and materials used can vary depending on the manufacturer and the particular CAT7 cable model. For the highest performance and reliability, it's recommended to choose CAT7 jumper cables from reputable brands that adhere to industry standards and quality control.
