With the continuous improvement of network transmission rate, the application of network is more and more extensive, and its demand and capacity for transmission bandwidth are higher and higher. As the infrastructure of data transmission, generic cabling system faces challenges. In particular, it puts forward higher requirements for the copper transmission system as a 10 Gigabit application.
When users have 10 Gigabit application requirements for copper cable system, for classea / cat 6A (super class VI) systems are often hesitant in the choice of shielding and non shielding. There are always some questions about system performance, cost, implementation, acceptance and maintenance. This article will focus on classea / cat Several aspects of 6A (super category 6) copper cabling system are analyzed in detail to facilitate users to make appropriate choices according to their own needs.
Note: ISO / IEC is called classea, TIA category 6a is abbreviated as cat 6A。 It is also called super six in China. Hereinafter collectively referred to as super class VI or super class VI systems.
Why choose super six systemsFirst of all, when the user has a copper interface and needs to meet the transmission rate of at least 10 Gigabit (10Gbps), he must select more than category 6 systems.
Secondly, from the perspective of international standards, ISO / IEC and TIA should or recommend super class 6 systems for data centers and newly installed projects:
-Classea cabling system shall be adopted: ISO / IEC 11801-5 data center, draft; ISO / iec11801-6 distributed building services, draft.
-It is recommended to use classea cabling system to support 10GBASE-T and new installation projects: ISO / iec11801-1, general, draft; ISO / iec11801-2 office environment, draft.
-Cat shall be used 6A cabling system: tia-1179-a medical and health, draft.
-Cat is recommended 6A cabling system: tia-942-b data center, draft; Tia-568.1-d commercial buildings; Tsb-162-a wireless LAN.
-Cat is recommended for new installation items 6A cabling system: tia-4966 educational institution; Tia-862-b intelligent building.
Thirdly, the domestic standard gb50174-2017 stipulates that for the horizontal subsystem undertaking data business, category 6a and above twisted pair cables (including category 6A connectors) shall be used.
