Since TIA officially issued the Cat.3 copper twisted pair standard (16Mhz bandwidth) based on 10BASE-T in 1990, the copper generic cabling system has been evolving iteratively.

ISO followed closely, issuing the class C standard (equivalent to Cat.3) in 1995, and then upgrading the cabling of Cat.3/class C to the transmission application of 100BASE-T4.

*Rongyang enterprise was established in Taipei in 1995 and has been rooted in the field of Ethernet generic cabling until now.

Later, TIA issued Cat.4 standard (20MHz bandwidth) supporting 16mbps token ring network transmission application and Cat.5 (Class D) standard supporting 100BASE-TX, which were also abolished at the beginning of the 21st century. 

(Cat.5 standard mentioned in some cabling and network technical indicators now actually refers to Cat.5e. However, in some special occasions, there are still a few applications of Cat.5 cables with expired standards. These cables have not passed the test of TSB95, so they are not products of Cat.5e standard.)


At present, Cat.5e unshielded twisted pair supporting 100Base-TX and 1000Base-T network transmission protocol and Cat.6 unshielded twisted pair supporting 1000Base-TX 

network transmission protocol are usually selected in the field of TIA-568.1 commercial building wiring standard.

In the field of TIA-942 data center cabling standard, 10GBase-T Cat.6A and Cat.7 or even Cat.8 (currently only supporting 30 meter links) cabling products are selected for the copper 

cable part. Although there are unshielded Cat.6A in the market, it is difficult to test the unshielded 6-pack-1 on-site, so most manufacturers choose shielded Cat.6A.

At present, the shielded system is strongly recommended for the copper cable in DC. According to the MICE standard, the strong electromagnetic interference caused by the 

very centralized power supply and other equipment in DC must be resisted by the Shielded Cabling System.

In the field of TIA-1005 Industrial plant Cable standard, because the electromagnetic interference in the factory environment is too strong and complex (time and space are 

uncertain, sometimes not), in order to avoid network data packet loss and even network transmission interruption caused by electromagnetic interference, it is necessary to use 

the shielded cabling system. The products cover 100m Cat.5e100Mbps)Cat.6(1Gbps)Cat.6A(10Gbps), even Cat.7 or Cat.7A Shielding Cabling System.
