The HR-722A Fiber Optic Communication System allows direct connection of VGA computers for signal transmission over Fiber Optic cable spanning distances to 2500 ft (0.75 kilometers) on multi-mode or 35 kilometers on single-mode fiber (approximate based on loss budget). The HR-722A features excellent picture quality with bright and sharp images. Gone are the usual signal degradation and smearing of coax or twisted pair video transmission at extended lengths. Signal integrity is also maintained through fiber optic cables' immunity to electrical interference and cross talk. The lightweight and small diameter fiber reduces installation time, particularly since only 1 fiber is needed. Fiber optic cable also has certain intrinsic benefits for installation success including resistance to electromagnetic interference (EMI), lightning, and the elimination of ground loops through electrical isolation.
