Category 5 standards.

The basic standard

Category 5 establishes the minimum performance requirements for generic telecommunications cabling systems.

The Category 5 specification defines acceptable performance levels and cable characteristics at speeds up tp 100 MHz. But in the period of time since Category 5 was introduces, information transmission and cabling technologies are advancing well beyond the Category 5 performance limits.

 

The future

New technologies such as Gigabit Ethernet (1000 Mbps) and 155-Mbps ATM (Asynchronous Transfer Mode) are pushing the limits of Category 5 cable. While there is no established standard above Category 5, new levels are emerging.

Category 5+ (Enhanced Category 5 or Level 6) cables offers better performance. But it must also meet tougher specifications, such as an attenuation-to-crosstalk ratio (ACR) of 10 db at 155 MHz and 4-pair power-sum NEXT (near-end-crosstalk) testing.

Category 5++ (Level 7) increases performance even more with the capability to support Gigabit Ethernet at 100 meters. Its bandwidth must be at least twice that of Category 5. Accordingly, test requirements increase. Category 5++ should meet an ACR level of 10 dB at 200 MHz and an even higher power-sum NEXT level.
