10GBASE-T Ethernet signalling refers to a standard for Gigabit Ethernet over copper wiring. This standard supports data transfer rates up to 10 gigabits per second (Gbps), ten times faster than traditional Gigabit Ethernet. Designed for use over Cat6, Cat6a, or Cat7 cabling, 10GBASE-T uses all four pairs of wires, providing a significant increase in bandwidth. The maximum distance for transmission depends on the type of cabling used. With Cat6 cabling, the distance is limited to 55 metres, while Cat6a and Cat7 can support distances up to 100 metres. 10GBASE-T Ethernet signalling employs a technology known as PAM16 (Pulse Amplitude Modulation), which allows it to maintain a high data rate over longer distances. It also incorporates error correction mechanisms to ensure data integrity. One of the main advantages of 10GBASE-T Ethernet signalling is its backward compatibility with older Ethernet technology. This means that existing network infrastructure can be upgraded to 10GBASE-T without requiring a complete replacement of the current cabling.
