natali2007 Posted January 5, 2008 Share Posted January 5, 2008 In recent years, networks of fiber-optic cable have been replacing electrical wire for transmitting telecommunications signals, Signals running through fiber-optic cables deteriorate, and wo the signals must be run through a piece of e3quiplent called a regenerator before being transmitted father. Light-Line is the leading manufacturer of signal regenerators. Therefore, Light-line is one of the companies that will most benefit if new long-distance fiber-optic telecommunications networks are constructed. Which of the following, if true, casts the most doubt on the prediction about light-ling’s prospects? 1) Telecommunications signals sent along electrical wires can travel much Farther than signals transmitted through fiber-optic before needing to be Regenerated. 2) Expanding its production of regenerators will require Light-line to spend Proportionately more on labor and materials. 3) The volume of signals that a fiber-optic cable can carry is several Thousand times greater than the volume that can be carried by an electrical Wire of similar size. 4) There are technologies that enable telecommunications signals to be transmil Without either wire or fiber-optic cable 5) Several manufacturers are developing regenerator technologies that will allow To be transmitted many times farther than at present before requiring regeneration Quote Link to comment Share on other sites More sharing options...
mnaumanca Posted January 5, 2008 Share Posted January 5, 2008 I am stuck b/w C and E but may incline towards C. Quote Link to comment Share on other sites More sharing options...
diya123 Posted January 5, 2008 Share Posted January 5, 2008 Option 5 seems to be incomplete.. Quote Link to comment Share on other sites More sharing options...
powerthelogic Posted January 6, 2008 Share Posted January 6, 2008 I feel C for not sure. E is the better one. Quote Link to comment Share on other sites More sharing options...
sun_twin Posted January 7, 2008 Share Posted January 7, 2008 I feel the answer is A E seems to be incomplete, C is talking about volume of signals and in a way supports fiber optics capability. Light Line will be successful, if signal regenerators are used. However option A, says that Telecommunication signals over electrical wires can travel more without the use of signal generators, hence this option clearly negates. Please dont get biased towards fiber optics and be judgemental. Suggestions Welcome... Quote Link to comment Share on other sites More sharing options...
siliconfish Posted January 7, 2008 Share Posted January 7, 2008 My choice is E. C is wrong because even if the volume is more the distance through which the fiber needs to be laid is not decreased. So if the distance is same, then the number of regenerators are still more. Quote Link to comment Share on other sites More sharing options...

sandeep_142 Posted January 9, 2008 Share Posted January 9, 2008 E is the only option that looks good to me Quote Link to comment Share on other sites More sharing options...
zuckerman Posted January 9, 2008 Share Posted January 9, 2008 I feel it's E. Quote Link to comment Share on other sites More sharing options...
