The RJ45 is a connector commonly used in structured cable networks. With up to 8 connection pins, it is adequate both for data networks (8 pairs), as well as telephone networks (2 pairs). It is usually used in networks compliant with standards TIA/EIA-568-B.
Data cable category Cat 6 complies with the standard for Gigabit Ethernet and it is backwards compatible, with the standards of the inferior categories (Cat 5/5e and Cat 3). Category 6 evolves over category 5E, allowing to achieve transmission frequencies of up to 250 MHz (in each pair) and 1 Gbps of throughput. It includes characteristics and specifications to avoid crosstalk and noise. This type of data cable can be used in 10BASE-T, 100BASE-T and 1000BASE-T (Gigabit Ethernet) compliant systems.
They are characterized for:
Comply with TIA/EIA-568B.2-1
Crucifix type padding
Transfer rate up to 1Gbps
Frequency range of up to 250 MHz
Includes rip cord to make it easier to strip the cable
Nominal impedance of 100 ohms
Maximum resistance per conductor below 9.38 ohms/100m
They achieve throughputs of up to 10Gbps in a frequency range of up to 500MHz.
