TIA- defines structured cabling standards for network infrastructure.
Copper categories:
- Cat e: MHz, Gigabit
- Cat : MHz, G to m
- Cat A: MHz, G to m
- Cat : GHz, /G
Distance limits:
- Horizontal runs: m max
- Patch cables: m total
- Total channel: m
Termination: Use TA or TB patterns. Maintain pair twists to within mm of termination.
