Copper transceivers are opto-electrical conversion modules that support twisted-pair transmission, providing a convenient high-speed upgrade solution for traditional copper cable networks. Copper transceivers adopt RJ45 interfaces, eliminating the need for fiber optic cabling and allowing direct connection to existing network cables, making them widely used in enterprise switches, routers, security monitoring and other scenarios. Copper transceivers support data rates from 1G to 10G, with transmission distances including 30m, 80m, 100m and other specifications, compatible with Cat5e, Cat6, Cat6a network cables, supporting hot swapping and auto-negotiation, featuring low power consumption, high stability and strong anti-interference capability, complying with industry standard certifications, and compatible with mainstream brand devices. They can meet high-speed transmission requirements in scenarios such as office networks, data center access and industrial control, making them the preferred solution for network upgrades that balance cost and performance.
