The CAT-2405 AIR is a high-end LAN cable designed for connecting audio components in streaming setups. It is based on our specially developed Air Helix construction, which enables low-loss and interference-resistant signal transmission. For this construction, we have designed a special clip that forms a stable supporting framework inside the cable. Several of these clips hold the signal pairs in a helical shape and at a defined distance freely in the air. The entire arrangement runs within a high-density shield. Two connecting bridges keep the clips evenly spaced and at the same time provide the necessary flexibility in the cable structure. Digital signal transmission: In mathematics, digital information is represented as binary values, but technically it is transmitted via analog voltage curves. To distinguish between states such as "0" and "1", voltage thresholds and time windows are defined. The transition between these states does not occur abruptly, but continuously—the signal passes through intermediate values, for example, between 0 and 5 volts. Capacitive loads, dielectric losses, noise, and external electromagnetic influences can distort these transitions. This results in timing shifts in the signal, known as jitter. Jitter makes it harder to assign data precisely in time and impairs the reconstruction of digital audio signals. Advantages of the Air Helix construction: The overall shielding made of dense braid, as well as additional foil shields for each pair of wires, effectively protect against external interference. The Air Helix construction uses air as a dielectric and ensures a constant distance between the wire pairs. This arrangement reduces crosstalk and capacitive losses, contributing to unadulterated signal transmission. Streaming components and integrated digital-to-analog converters (DACs) benefit from the improved signal quality and can process data more precisely. CAT connector with rotation mechanism: Conventional RJ45 connectors can only be plugged in at a fixed orientation. Depending on the position of the socket, this can result in unfavorable cable routing and mechanical stress on the connector, cable, and socket. To counteract this, we use rotatable RJ45 connectors with a 180° mechanism. Each connector can be rotated by about ±45°, resulting in a total adjustability of about ±90° between both connectors. This allows the cable to be routed without tension and in a space-saving manner.

Strictly speaking, "digital" exists only in mathematics as a binary number system. In technical reality, there are no purely digital signals. To identify zeros and ones, electrical voltage thresholds and time windows are defined. When switching from zero to one or vice versa, the signal passes through all intermediate values — for example, from 0 volts to 5 volts. Capacitive loads, dielectric losses, noise, and electromagnetic interference caused by the cable additionally affect this transition. This results in timing deviations, known as jitter, which complicates the precise reconstruction of the audio signal. The Reference CAT 8.1 cable is a LAN cable specifically designed for connecting high-end components in a home network. An additional shielding mesh, the so-called hyper-shield, protects the sensitive signals from electromagnetic interference. Furthermore, each data pair is individually shielded with an additional foil layer. This combination effectively reduces interference and supports streaming players and built-in digital-to-analog converters (DACs) in reproducing the audio signal with minimal loss and maximum precision. This ensures that the Reference CAT 8.1 cable provides a stable and high-performance connection - ideal for demanding audio and video streams in a home network.

CAT cables for high-resolution streaming – audiophile network technology
Why does the quality of network cables matter for high-resolution streaming?
In the world of digital audio, it is often overlooked that “digital” signals are physically transmitted as analog voltage curves. When distinguishing between “0” and “1,” the signal continuously passes through all intermediate values – for example, from 0 to 5 volts. Capacitive loads, dielectric losses, electromagnetic interference, and noise can distort these transitions and lead to time shifts, known as the jitter effect. This impairs precise clocking and makes it difficult to accurately reconstruct the audio signal in streaming components and digital-to-analog converters.
