CAT5, with a bandwidth of 100m, is suitable for networks below 100m; CAT5e, with 155m bandwidth, is the current mainstream product.
Lan CAT 5: this kind of cable increases the winding density, and is coated with high-quality insulating material with a transmission rate of 100MHz. It is used for voice transmission and data transmission with a maximum transmission rate of 10Mbps. It is mainly used for 100Base-T and 10Base-T networks. This is the most commonly used Ethernet Lan cable.
CAT 5e Lan: CAT5e line has small attenuation, less crosstalk, higher attenuation to crosstalk ratio (ACR) and structural return loss, smaller delay error, and greatly improved performance. CAT5e network cable is mainly used for Gigabit Ethernet (1000Mbps).
