Which cable is an Enhanced Cat5 that supports up to 1 Gbps at 100 meters?

• A. Cat5e
• B. Cat6
• C. Cat6a
• D. Plenum-Rated Cable

Answer: (A)

The term "enhanced Cat5" refers to Cat5e, which was introduced to address the performance limitations of Cat5 and to support Gigabit Ethernet over the standard 100-meter copper Ethernet segment. It achieves 1 Gbps operation (1000BASE-T) at up to 100 meters by tighter twists and improved insulation to reduce crosstalk and noise. Cat6 and Cat6a are newer standards that provide higher performance and can support 10 Gbps on shorter distances, but they are not the enhanced Cat5. Plenum-rated cable is about the jacket construction for use in air-handling spaces and does not define data rate. So the Enhanced Cat5 that supports up to 1 Gbps at 100 meters is Cat5e.
