The diameter of a fiber optic cable is:
Correct answer: B. 62.5 microns
- A. 62.5 mm
- B. 62.5 microns
- C. 6.25 cm
- D. 5.62 microns
Explanation
The correct answer is (b) 62.5 microns.62.5 mm is too large for a fiber optic cable. A typical fiber optic cable has a diameter of around 125 microns, which is much smaller than a millimeter.Fiber optic cables use light to transmit data. They are made of glass or plastic fibers that are very thin and flexible. Fiber optic cables have several advantages over traditional copper cables, including:Higher bandwidth: Fiber optic cables can transmit data at much higher speeds than copper cables.Lower signal loss: Signals travel through fiber optic cables with less loss than they do through copper cables. This means that data can travel longer distances over fiber optic cables without needing to be regenerated.Immunity to interference: Fiber optic cables are not susceptible to electromagnetic interference (EMI) or radio frequency interference (RFI). This makes them ideal for use in environments where there is a lot of electrical noise.
