There are only three test standards for the Category 6 network wire, and the others are similar.
(1) EIA/TIA-568A, TIA/EIA-568 is the standard for integrated wiring systems in North America, and the latest available version is ANSI/TIA-568.C
EIA (Electronic Industries Association) is an organization that specializes in the electrical properties of interfaces. The established standards are RS-232, RS-485, etc.; and TIA (Telecommunications Industries Association) is specially developed. Standard organization for communication wiring and architecture.
At the beginning of 1985, there was a lack of standards for communication wiring systems in buildings in terms of computers and communications. The CCIA (Computer Communications Industry Association) required the EIA organization to develop standards for computers and communications, so in 1991 In July, the first version of the standard appeared! That is EIA/TIA-568.
The second version of TIA/EIA-568 was issued in 1995 and is the most widely accepted version, ANSI/TIA/EIA-568.A.
In 2001, TIA/EIA-568 released the third version, ANSI/TIA/EIA-568.B[1].
The ANSI/TIA/EIA-568-B.1 cabling standard details important standard requirements such as topology, cable and cabling length required for design and construction. For testing purposes, the 568-B.1 standard defines, for example, insertion loss, near-end crosstalk (NEXT), far-end crosstalk (FEXT), return loss, and other measurement parameters associated with structured cabling systems. This standard defines the performance test metrics for installed cables in detail.
The ANSI/TIA/EIA-568.B standard was replaced by ANSI/TIA-568.C in 2009 [2].
ANSI/TIA-568.C is divided into 4 parts:
ANSI/TIA-568.C.0: Common wiring standards for user buildings
ANSI/TIA-568.C.1: Commercial Building Telecommunications Cabling Standards
ANSI/TIA-568.C.2: Balanced Twisted Pair Telecommunications Cabling and Connection Hardware Standards
ANSI/TIA-568.C.3: Fiber Cabling and Connection Hardware Standards [1]
(2)ISO/IEC11801: International Standard ISO/IEC 11801 Full Name Information Technology - User Infrastructure Structured Cabling, which was prepared and revised by the ISO/IEC JTC1 SC25 Committee of the International Organization for Standardization. This standard describes how to design a general-purpose structured cabling for multiple network applications such as analog and ISDN technologies, multiple network transport protocols such as 10BASE-T, 100BASE-T, 1000BASE-T, 1000BASE-SR, etc. It can also be used in control systems, industrial automation, HDBASE-T and other applications. The performance levels and transmission distances of twisted pair and cable routing are clearly stated in the standard.

The third edition of ISO/IEC 11801 (draft) is the biggest change since 2010. The original distributed multiple structured cabling standards are integrated. The new version will consist of six parts:
ISO/IEC new version standard number
Alternative standard number description
ISO/IEC 11801-1 ISO/IEC 11801:2002 Requirements for structured cabling for twisted pair and cable
ISO/IEC 11801-2ISO/IEC 11801:2002 commercial (enterprise) building wiring
ISO/IEC 11801-3ISO/IEC 24702 Industrial Wiring
ISO/IEC 11801-4ISO/IEC 15018 household wiring
ISO/IEC 11801-5 ISO/IEC 24764 data center wiring
ISO/IEC 11801-6 ISO/IEC TR24704 Distributed Building Service Facility Cabling
Channel and link level
The standard defines the link and channel transmission level of a 100Ω balanced four-pair twisted pair, including the following levels:
Class A: Supports bandwidth to 100 kHz link and channel
Class B: Supports bandwidth to 1MHz link and channel
Class C: Supports bandwidth to 16MHz link and channel
Class D: Supports bandwidth to 100MHz link and channel
Class E: Supports bandwidth to 250MHz link and channel
Class EA: Supports bandwidth to 500MHz link and channel
Class F: Supports bandwidth to 600MHz link and channel
Class FA: Supports bandwidth to 1000MHz link and channel
Class I: Supports links and channels with bandwidths up to 2000MHz (valid only in the 30m channel range)
Class II: Links and channels supporting bandwidth up to 2000MHz (valid only in the 30m channel range) In the current second edition, The recommended link level for buildings is Class D (Super Category 5) or higher; in the third edition, the recommended link level is Class EA (Super Category 6) or higher.
The above described link and channel level components can be made up of corresponding grades of twisted pair and connectors. The described twisted pair and connector standards can be referenced to the IEC 60603-7 connector standard and the IEC61156 twisted pair standard. The corresponding levels are as follows:
Category 1: Cables and connectors supporting bandwidth up to 100 kHz
Category 2: Cables with support bandwidth up to 1 MHz and connectors
Category 3: Cables and connectors supporting bandwidth up to 16 MHz
Category 5 (also commonly referred to as Category 5E, Super 5): Cables and connectors supporting bandwidth up to 100MHz
Category 6 (six types): Cables with bandwidth up to 250MHz and connectors
Category 6A (Super Category 6): Bandwidth support To 500MHz cable and connector
Category 8.1 (draft, TIA also known as Category 8): Supports bandwidth to 2000MHz cable and connector
Category 7 (Category 7) within 30 meters: Supports bandwidth and connection to 600MHz cable and connection
Category 7A (Super Seven): Cables and connectors supporting bandwidth up to 1000MHz Category 8.2 (draft): Cables and connectors supporting bandwidth up to 2000MHz within 30 meters Category8Category 8.1 and Category 8. 2 are called 8 classes, all of which can support 2000MHz transmission within 30m channel length. When the channel length is in the range of 30 meters to 100 meters, the performance of Category 8.1 is similar to that of Category 6A. The performance of Category 8.2 and the Category 7A similar cable level editing standard define multiple fiber optic cable levels: OM1 multimode fiber cable: Mode fiber type 62.5μm, support modal bandwidth 200MHz*kmOM2 multimode fiber cable at 850nm: multimode fiber type 50μm, support modal bandwidth 500MHz*kmOM3 multimode fiber cable at 850nm: multimode fiber type 50μm, support modal bandwidth at 850nm 2000MHz*kmOM4 multimode fiber optic cable: multimode fiber type 50μm, modal bandwidth 4700MHz*kmOS1 single mode fiber optic cable at 850nm: single mode fiber type 9μm, support attenuation 1dB/kmOS2 single mode fiber optic cable: single mode fiber type 9μm, support attenuation 0.4 dB/km
