BAGHDAD - Staff Sgt. Jose Gallego, of Bogota, Colombia, a computer systems repairer assigned to C Company, Division Special Troops Battalion, 1st Cavalry Division, prepares to splice a fiber optic cable at Joint Security Station Ur, here, June 19. "When we come out and do this, we can actually see progress," said Sgt. 1st Class Johnnie Pippin, of Liberty Center, Ohio, a communications chief. "It feels good to provide something and actually see it work." According to Pippen, fiber optic cables use light signals to carry more information much faster than Ethernet cables.
