มาตรฐาน Ethernet
มาตรฐาน Ethernet ทุกเวอร์ชันพร้อมความเร็ว คุณสมบัติ และความเข้ากันได้
Ethernet standards define wired networking protocols from 10 Mbps to 400 Gbps. The IEEE 802.3 working group maintains specifications including Fast Ethernet (100BASE-TX), Gigabit Ethernet (1000BASE-T), 10GBASE-T, and 25/40/100/400GbE for data centers. Power over Ethernet (PoE, IEEE 802.3bt) delivers up to 90W, powering IP cameras, wireless access points, and even laptops over the same cable.
1000BASE-T (Gigabit Ethernet)
5/101 Gbps Ethernet over Cat5e or better cabling. The universal wired networking standard for homes, offices, and servers. Every modern router, switch, and NAS includes …
100BASE-TX (Fast Ethernet)
2/10100 Mbps Ethernet over Cat5 or better cabling. The baseline wired networking standard since the late 1990s. Still found on IoT devices, printers, and budget …
10GBASE-T (10 Gigabit Ethernet)
8/1010 Gbps Ethernet requiring Cat6a (up to 100m) or Cat6 (up to 55m). Standard for data centers, NAS-to-NAS links, and high-end workstations. Increasingly found in …
2.5GBASE-T
7/102.5 Gbps Ethernet designed to work over existing Cat5e cabling. The practical upgrade path for homes and offices without rewiring. Increasingly standard on new Wi-Fi …
5GBASE-T
5/105 Gbps Ethernet over Cat5e (up to 100m) or Cat6. Fills the gap between 2.5G and 10G. Less common than 2.5G due to similar cost …
Cat5e (Ethernet)
3/10Enhanced Category 5 cabling supporting Gigabit Ethernet (1 Gbps) at up to 100 meters. The minimum recommended Ethernet cable for home networking.
Cat6 (Ethernet)
5/10Supports 10 Gbps up to 55 meters or 1 Gbps at 100 meters. Improved crosstalk rejection over Cat5e. Good for home and small office installs.
Cat6a (Ethernet)
7/10Augmented Cat6 supporting 10 Gbps at the full 100-meter distance. Recommended for new construction and structured cabling installations.
Cat7 (Ethernet)
5/10Shielded cabling supporting 10 Gbps with better noise rejection than Cat6a. Uses GG45 or TERA connectors in the standard but most installations use RJ45.
Cat8 (Ethernet)
6/10Supports 25-40 Gbps at up to 30 meters. Designed for data center switch-to-switch links, not typical home or office runs.
