Cat5e、Cat6、Cat6a和Cat7

Cat5e (Super Category 5) ， Cat6 (Category 6)， Cat6a (Super Category 6) and Cat7 (Category 7)

Network cable (network patch cable or twisted pair), which is usually used with RJ45 crystal head.

1. Cat5e cable VS Cat6

Features / Categories	Cat5e	Cat6
Transmission speed	1000Mpbs	10Gbps(37-55m)
Frequency bandwidth	100Mhz	250Mhz
Transmission distance	100m	100m/55m(10GBASE-T)
Wire gauge standard	24-26AWG	22-24AWG
Performance	Interference/Crosstalk：Cat5e>Cat6	low return loss and insertion loss

The main difference between Cat5e and Cat6 is transmission performance. cat6 cable has an internal splitter to reduce interference or near-end crosstalk (NEXT), which also improves far-end crosstalk (ELFEXT) compared to Cat5e cable, and has lower return loss and insertion loss

2. Cat6 VS Cat6a VS Cat7

Features / Classification	Cat6	Cat6a	Cat7
Transmission speed	10Gbps(37-55m)	10Gbps(100m)	10Gbps(100m)
Connector	RJ45	RJ45	GG45
Frequency bandwidth	250MHz	500MHz	600MHz
Interference	Cat6>Cat6a>Cat7	Cat6>Cat6a>Cat7	Cat6>Cat6a>Cat7
Standard	TIA/EIA	TIA/EIA	无TIA/EIA
Application Scenarios	Home Network	Home Network	Multi-application or enterprise networking

Cat7 cable greatly reduces crosstalk noise compared to Cat6 and Cat6a cables

Cat7 network cable has a special connector, it has a GigaGate45 (CG45) connector type
