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?

  1. 0 percent
  2. 36 percent
  3. 50 percent
  4. 80 percent
  5. 100 percent

Answer(s): B
