2.5GBASE-T Ethernet signalling refers to a standard for Ethernet connectivity that delivers a data rate of 2.5 gigabits per second (Gbps). This technology utilises existing Category 5e (Cat5e) or Category 6 (Cat6) twisted pair cabling over distances up to 100 metres. The key advantage of 2.5GBASE-T Ethernet signalling is its ability to provide higher network speeds without requiring a complete overhaul of existing cabling infrastructure. This makes it a cost-effective solution for enhancing network performance, especially in environments where upgrading to higher category cabling is impractical or cost-prohibitive.
