What is the difference between an HO and LO optical link? - Mr Watson, Come Here most recent 30 from http://mrwatsoncomehere.com 2010-07-30T02:43:21Z http://mrwatsoncomehere.com/feeds/question/8 http://www.creativecommons.org/licenses/by-nc/2.5/rdf http://mrwatsoncomehere.com/questions/8/what-is-the-difference-between-an-ho-and-lo-optical-link What is the difference between an HO and LO optical link? Bruce Fitzsimons 2009-10-13T07:10:47Z 2009-10-13T07:10:47Z <p>I've seen references to HO and LO optical links. This apparently means High Order and Low Order, but that isn't a lot of help. I've seen references to eigenvalues on Wikipedia, but that wasn't clear either.</p> <p>What makes an LO link? Conversely what makes a HO link and why do we need to differentiate?</p>
