True, single mode vs multi mode. But you still need qualified/experienced installers with the proper tools to do the terminations. It's not rocket surgery, but it's quite different than CATx termination with a punch tool. First you must polish the tip of the fiber strand after cutting to length, so it has a perfectly flat face that is 90 degrees perpendicular to the strand length. Note the fiber strands are finer than a bleach blonde Playmate's ultra thin hair. Next, fiber doesn't terminate at the panel. It always terminates in a male connector that gets plugged into the distribution panel. Assembling the connectors is a rather delicate operation. The end of the fiber must be perfectly flush with the connector edge, lest you have an air gap between faces, which causes serious loss at the junction. With both connectors inserted into the panel, the two flat strand faces should be in full contact with each other, perfectly aligned. Those with meat hands need not apply. For everyone else with some manual dexterity, it just takes instruction, a little practice with a couple feet of fiber cable, a few dozen end connectors, head mounted magnifier plus light, and some patience. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
