Sample cards
What is the maximum data rate of Cat5e cable, and over what distance?
1 Gbps over 100 meters — the baseline for gigabit Ethernet runs.
How fast can Cat6 cable carry 10 Gbps, and what is its limit at that speed?
Cat6 supports 10 Gbps but only up to about 55 meters; beyond that it falls back to 1 Gbps up to 100 meters.
What advantage does Cat6a have over Cat6?
Cat6a sustains 10 Gbps over the full 100-meter run and has better resistance to crosstalk (alien crosstalk).
Which coaxial cable type and impedance are standard for cable internet and TV?
RG-6 coax at 75 ohms, terminated with a threaded F-type connector.
What is the key difference between single-mode and multimode fiber?
Single-mode uses a tiny core and laser light for very long distances (kilometers); multimode uses a larger core and LED light for shorter runs, typically within buildings.
