Assume that the optical power transmitted by a 62.5/125 multimode fiber is distributed uniformly across its core. If this fiber is perfectly coupled (i.e., the two fibers are aligned and abutted) to a 50/125 fiber, what is the percent of power that is lost?

Which characteristic is an advantage of copper based media over optical fiber cable?

If the input signal power to a communication system is 1 W and the output power is 1 mW, the system attenuation is:

An existing ceiling raceway system has 115,000 sq mm (177 sq in) of cross-sectional area available for distribution of cable runs. How many can be served by the existing system?

Cables are installed in a ceiling in a straight line. The ceiling run is 60 m (200 ft) in length. What is the MINIMUM number of J-hooks required to support the cables?

You are designing a horizontal pathway system where you will provide 100 mm (4 in) conduit and pull boxes. The building architectural elements will only allow for a single layer of conduits (not stacked). The main horizontal pathway system consists of five 100 mm (4 in) conduits. Large single sheath copper cables are not expected to be placed. Which of the following is the MINIMUM width pull box that is to be provided?
