As the draft standard IEC 46C/976/NP and ISO / IEC TR 11801-99-1, for 40 Gbit / s transmission rate applicable Class 8 balanced copper cabling system and the new international standard is currently in the preparation phase. Unlike a few years ago these criteria discussed in Class 8 data cables symmetrical proposed standard, then the proposed standards for the field of application of structured cabling and no more than 1.2 gigahertz (GHz) frequency limit, while the International Organization for Standardization predicted today the only application field is the biggest limiting frequency of 2 GHz data center.
Standard ISO / IEC TR 11801-99-1 provides active-point connection between devices a maximum distance of 30 meters, including 26 meters long and is located on both sides of the installation cable 2 m long jumpers. This connection can replace costly data center fiber optic and shielded pair wire feeders (twinax cabling).
Although the new standard is still in the drafting stage, Deteweile company already developed the first compact S / FTP AWG23 cable - "CU 8203 4P", which fully comply with ISO / IEC stipulated in the draft of the new 8.2 type cable expectations requirements. Since then, the company will further introduce other new S / FTP and F / FTP cable and the appropriate jumper (flexible cables). Deteweile company emphasized, taking into account the attenuation (NEXT, PS-NEXT), these new cables in the current study and the limits of the capacity on the basis of further provides a lot of spare capacity.
In the coming months, the channel specification precise parameters will be drafted. However, many issues remain to be resolved, especially with the future of connected technologies and transfer methods related issues. Deteweile customers will be happy to any questions in this regard to provide consulting services.
