We offers a variety of Fiber Optic Patch Cords. Singlemode fiber cable is primarily used for applications involving extensive distances and only handles one wavelength (or mode) of light. Multimode fiber, however, is the cable of choice for most common fiber systems as it can handle multiple wavelengths of light along the same fiber core. The common core sizes of multimode fiber are 62.5 micron and 50 micron. We carry single mode and multimode optical fiber patch cables with a variety of connector types such as LC, SC, ST,FC, MT-RJ and so on. Duplex fiber cables consist of two fiber cores and can be either multimode or single mode. This dual core system allows for the bi-directional transfer of data, as opposed to simplex fiber cables, which only propagate data in one direction. Simplex fiber is also available in either the multimode or single mode variety.
