How 1000BaseCX Works
1000BaseCX is an extension of standard Ethernet technologies to gigabit-level network speeds. 1000BaseCX is normally implemented using shielded twisted-pair (STP) cabling. Cable segments have a maximum length of only 25 meters. 1000BaseCX employs 8B/10B coding, with serial transmission rates of 1.25 Gbps. STP cabling is standard 150-ohm balanced cabling and should have a quality slightly better than IBM Type I cabling.
1000BaseCX is intended mainly for connecting high-speed hubs, Ethernet switches, and routers together in wiring closets. Common implementations for 1000BaseCX are in switch-switch and switch-server connections, with switch-server connections being the most frequently implemented use for 1000BaseCX.
