BAGHDAD - Spc. Jorge Lugo (left) assigned to Company C, Division Special Troops Battalion, 1st Cavalry Division, of San Juan, Puerto Rico, begins the process of cutting a fiber optic cable, May 13, so he can let Iraqi Army Sgt. 1st Class Saad Jafar Kareem demonstrate re-joining the delicate glass cables using a fusion splicer to melt the tiny glass fibers together. Fusion splicing creates a seamless joint in a fiber optic cable, which eliminates the need to install an entire new cable. Lugo said Kareem, who is a trained electrician, is a quick learner.
