Standard High Power Laser Transmission Cables

Multimode Fiber Optics, Inc. standard High-Power Laser Transmissions Cables are available with either our unique HP-SMA905 or HP-635 connector. The HP-SMA905 connector holds the fiber tip cantilevered within a SMA905 connector ferrule, which is bored out to remove epoxy and other material from the fiber perimeter. This significantly reduces fiber breakdown, usually the result of beam misalignment in which the laser energy is focused outside the fiber core on portions of the connector that could easily burn, causing fiber damage. A heat-sink is attached to the rear of the connector, which conducts extraneous heat away from the fiber, further reducing the possibility of breakdown. The HP-635 incorporates the same features in a simplified .250”OD x 1”L stainless steel ferrule, which can be held in standard optical positioners. The cantilevered fiber and heat-sink can also be incorporated into other connector types, such as ST, FC, etc., at additional cost. The fibers are double-sheathed in super-rugged, flexible stainless steel square lock cable, with an internal PVC/Kevlar sheath. High temperature epoxies are used throughout to ensure mechanical stability. All fibers are silica/silica, 0.22 numerical aperture.
