Question

In an optical fibre, the power drops by a factor of 10 approximately every 30 km. If the transmit power is 0.3 W

(= 3x10-1), how far will a signal be transmitted before the power is attenuated to 300 μW? Include a table showing the signal power vs. distance in 30 km intervals as part of your answer.

If a high-quality coaxial cable (LDF5-50A) operating at 2 Mbps is used instead of an optical fibre, how would you expect the calculated distance value to change?

Top Answer

The reduction of power occurs in the Optical fibre cable when the signal is passing from one position to another regarded as... View the full answer
