Class II: Up to 2 GHz (2000 MHz) using Category 8.2 cable and connectors (ISO/IEC 11801-1, Edition 1.0 2017-11) The standard link impedance is 100 Ω. (The older 1995 version of the standard also permitted 120 Ω and 150 Ω in Classes A−C, but this was removed from the 2002 edition.)
Category 1 cable, also known as Cat 1, Level 1, or voice-grade copper, is a grade of unshielded twisted pair cabling designed for telephone communications, and at ...
[5]: §4.2.6 A cable of about 5 meters (16 feet) can be manufactured to Category 1 specifications easily and inexpensively by using 28 AWG (0.081 mm 2) conductors. [70] With better quality construction and materials, including 24 AWG (0.205 mm 2 ) conductors, an HDMI cable can reach lengths of up to 15 meters (49 feet). [ 70 ]
The current revision includes Category 5e (100 MHz), 6 (250 MHz), 6A (500 MHz), and 8 (2,000 MHz). Categories 7 and 7A were not officially recognized by TIA and were generally only used outside the United States. Category 8 was published with ANSI/TIA‑568‑C.2‑1 (June 2016) [9] to meet the performance specification intended by Category 7.
Category 2 cable, also known as Cat 2, is a grade of unshielded twisted pair cabling designed for telephone and data communications. The maximum frequency suitable for transmission over Cat 2 cable is 4 MHz, and the maximum bandwidth is 4 Mbit/s. [1] [2] Cat 2 cable contains 4 pairs of wires, or 8 wires total. [3]
Schematic representation of measurement categories. Measurement category is a method of classification by the International Electrotechnical Commission (IEC) [1] of live electric circuits used in measurement and testing of installations and equipment, usually in the relation within a building (residential or industrial).

The first types of small modular telephone connectors were created by AT&T in the mid-1960s for the plug-in handset and line cords of the Trimline telephone. [1] Driven by demand for multiple sets in residences with various lengths of cords, the Bell System introduced customer-connectable part kits and telephones, sold through PhoneCenter stores in the early 1970s.
