QED REFERENCE Ethernet

Hanterar det högsta av högupplösta ljud - och mer.
Designad för att ge den mest exakta, mest stabila anslutningen mellan nätverksenheter. Perfekt för att ansluta en högupplöst digital ljudstreamer till ett lokalt nätverk, Reference Ethernet har mer än tillräckligt med bandbredd för att hantera de datahastigheter som krävs av 32 bitar/384 kHz och DSD512 ljudfiler. Reference Ethernet är noggrant konstruerad och är en Klass I Kategori 8.1-kabel och kan stödja 40G Ethernet - och så har det utrymme för att klara även de mest dataintensiva applikationerna

Teknisk stamtavla
QED har designat och konstruerat överlägsna analoga och digitala kablar i mer än 50 år, och dess nya referens Ethernet-kabel bygger på resultaten från företagets omfattande forskning om kabeldesign sedan 1995.

"In short, this is a beautifully made Ethernet cable that works extremely well and will certainly not become obsolete in the foreseeable future."

Specified to perform

An uncompromised specification and state-of-the-art engineering results in a cable with a maximum data rate of 40 Gb/s. This is well in excess of what is required to handle even the most demanding data streams, and means Reference Ethernet is easily able to cope with the highest of today’s high-resolution digital audio files and is future-proofed to handle whatever comes next.Minimising crosstalk and insertion loss

In order to keep signal noise and crosstalk to an absolute minimum, Reference Ethernet uses 99.999 % oxygen-free copper twisted-pairs - with a dissimilar twist rate for each pair - to maximise noise-rejection characteristics. For minimal ‘insertion loss’ - which is the reduction of signal strength at the end of the cable compared to that at the start - Reference Ethernet uses an aluminium mylar wrap, within a foil wrap, within a ferrite-impregnated jacket. As a result, the cable comfortably exceeds the CAT 8 insertion loss standard. This over-specified arrangement also means Reference Ethernet easily outperforms the CAT 8 standard for ‘attenuation-to-crosstalk ratio’ which is an indicator of the margin by which it avoids introducing any errors into the data stream.Reducing return loss

Reference Ethernet also performs way beyond the CAT 8 requirements where ‘return loss’ is concerned. Any impedance mismatch between the cable and the equipment it’s connected to can cause the signal to be reflected back and forth. Thanks to its precision-engineered, gold-plated Telegärtner plugs with 360-degree shielded die-cast zinc bodies, reflections are minimised and all of the signal is delivered to the load. The cable is finished in a stylish pearl white PVC jacket to compliment any hi-fi set-up.Technical Specifications
