A company is installing new network cabling to support future 10GBASE-T connections up to 100 meters with reduced crosstalk. Which cable type BEST meets this requirement?
- ACat3
- BCat5e
- CCat6a
- DRG-6
Show answer & explanationAnswer & explanation
Correct answer: C. Cat6a
Cat6a cable supports 10GBASE-T at full 100-meter distances with improved shielding and reduced crosstalk compared to Cat5e, which only supports 10Gbps up to 45 meters. Cat3 and RG-6 do not support these speeds.
Why the other options are wrong
- A. Cat3 is legacy cabling that only supports very low speeds, unsuitable for modern networks.
- B. Cat5e supports only up to 1Gbps reliably at 100m (10Gbps limited to ~45m with crosstalk issues).
- D. RG-6 is coaxial cable used for cable TV/internet, not twisted-pair Ethernet.
Cat6a Cable
An enhanced twisted-pair Ethernet cable standard supporting 10Gbps speeds at full 100-meter distances with reduced crosstalk.
- Supports 10GBASE-T at 100m
- Improved shielding vs Cat6
- Backward compatible with Cat5e/Cat6 devices
Memory trick: '6a' Adds Armor for full 10G at 100m.
