What are the disadvantages of fiber-optic cables??

What will be an ideal response?


Fiber-optic cable has two small but significant disadvantages. First, due to the way the light source and photo receptor arrangement works, light pulses can travel in one direction only. Thus, to support a two-way transmission of data, two fiber-optic cables are necessary. For this reason, most fiber-optic cable is sold with at least two (if not more) individual strands of fiber bundled into a single package. ?A second disadvantage of fiber-optic cable is its higher cost, but this disadvantage is slowly disappearing. For example, it is now possible to purchase bulk, general purpose duplex (two-strand) fiber-optic cable for approximately $.50 per foot (as opposed to paying a few dollars per foot several years ago), which is close to the price of many types of coaxial cable and shielded twisted pair cable.?
