Cable Connections

Question 1

Cat5e

Answer 1

Max Speed: 1 Gbps
Max Distance: 100 meters
Frequency: 100 MHz
Use Case: Standard for home and small business networks

Question 2

Cat6 / Cat6a (Category 6 & 6a) – RJ-45 (Ethernet)

Answer 2

1 Gbps (100 meters) / 10 Gbps (up to 55 meters)
10 Gbps (100 meters)
250 MHz (Cat6), 500 MHz (Cat6a)
Use Case: Business networks, data centers, improved signal quality over Cat5e

Frequency: 600 MHz
Connector: GG45 or TERA (Backward compatible with RJ-45)
Use Case: Data centers, high-performance networks

Question 4

Cat8

Answer 4

Max Speed: 25-40 Gbps (up to 30 meters)
Frequency: 2000 MHz
Connector: GG45, TERA, or RJ-45
Use Case: Short-distance data center applications, backbone connections

Question 5

Shielded Twisted Pair (STP)

Answer 5

Twisted-pair cable with foil or braided shielding around each pair
Environments with high EMI, such as industrial sites or near electrical cables

Question 6

Unshielded Twisted Pair (UTP)

Answer 6

Standard twisted-pair cable without additional shielding
Most common in homes and offices where EMI is low
