CAT7 and CAT8 network cables differ mainly in transmission speed and frequency.

CAT7 supports transmission speeds up to 10 Gbps with a frequency of 600 MHz, while CAT8 supports speeds up to 25 Gbps or 40 Gbps with a frequency of 2000 MHz.

During production, high-quality conductor materials should be used, the spacing between pairs and insulation thickness should be strictly controlled, effective shielding techniques such as double-layer shielding should be employed to reduce crosstalk and external interference, ensuring signal integrity.

Double-layer shielding structures should be adopted, with an inner layer of aluminum foil and an outer layer of braided mesh, to enhance the cable's anti-interference capability; at the same time, the arrangement of pairs should be optimized, and the spacing between pairs should be increased to reduce crosstalk.

By optimizing pair geometry, precisely controlling impedance matching, using high-quality insulation materials, and employing effective shielding techniques, return loss can be minimized to ensure signal integrity.

Automatic tensioning track and control help maintain consistent tension throughout the wrapping process, ensuring uniform coverage, avoiding the tension fluctuation during the tape consumption, reducing the break-down rate.

PCIe 6.0 and PCIe 7.0 cables differ in transmission speed and signal integrity requirements. PCIe 6.0 uses PAM4 modulation technology with a transmission speed of up to 64 GT/s, while PCIe 7.0 further increases the transmission speed, employs more advanced modulation technologies, and requires higher signal integrity and lower latency.

Low-loss conductor materials should be selected, the geometric structure of pairs should be optimized, crosstalk between pairs should be reduced, high-quality insulation materials should be used, and production processes should be strictly controlled to reduce signal delay and attenuation.

By precisely controlling the conductor diameter, insulation thickness, and spacing between pairs, and using impedance analyzers for real-time monitoring, ensuring that the cable impedance is within the specified range to avoid signal reflection and loss.

The use of effective shielding technology, such as double-layer shielding, the use of low-resistance conductor materials, optimize the geometry of the wire pair, reduce electromagnetic leakage, and control the EMI level of the wire.

High transmission speeds require stricter signal integrity control, necessitating the use of low-loss conductor materials, precise control of pair geometry, and reduction of crosstalk and delay to meet high-speed transmission demands.

Insulation materials with low dielectric constant and low loss tangent, such as PTFE or PI, should be chosen to reduce signal attenuation and delay.

Using Time Domain Reflectometry (TDR) and other testing equipment, real-time monitoring of cable transmission delay can be conducted to ensure it is within the specified range, preventing signal transmission quality issues.

Precise control of conductor diameter and insulation thickness, optimization of pair arrangement, reduction of crosstalk between pairs, and use of low-resistance conductor materials can effectively control cable resistance and inductance.

Using spectrum analyzers and other testing equipment, real-time monitoring of cable transmission speed can be conducted to ensure it meets design requirements, preventing signal transmission quality issues.

The temperature control of the extruder directly affects the quality of the insulation or sheath layer. Too high or too low a temperature will to unstable material properties and affect the overall quality of the cable.

The pitch of a stranding machine determines the flexibility and tensile strength of the stranded wire. A shorter pitch increases flexibility, while a longer pitch enhances tensile strength.
