Cat 7 uses shielded twisted pair (STP) cables. This means each pair of wires is shielded. It helps block interference and gives stable data.
Main Features of Cat 7
- Speed: Up to 10 Gbps
- Bandwidth: Up to 600 MHz
- Shielding: S/FTP (Shielded Foiled Twisted Pair)
- Connector Type: GG45 or TERA, also supports RJ45
- Distance: Up to 100 meters at 10 Gbps
Cat 7 is built for future-proofing networks. It works well in noisy environments or when cables are near power lines.
Where is Cat 7 Used?
Cat 7 is used in:
- Data centers
- Smart homes
- Office networks
- Servers
- Industrial control systems
It is good for long runs and systems that need high reliability.
