wire used for OS1 Simplex Patch Cord from the device

OS1 Simplex Patch Cord multi-mode fiber and two single-mode fiber, multimode fiber and single mode fiber difference, mainly in the transmission of light in different ways, of course, are not the same bandwidth capacity. Larger diameter multimode fiber, different wavelengths and phase of the beam reflected along the fiber wall kept forward transmission, resulting in dispersion, limits the transmission between the two repeaters distance and bandwidth, the bandwidth of multimode fiber is about 2.5Gbps. Smaller diameter single-mode fiber, the light in which the straight lines, very few reflections model depends on the number of core diameter, numerical aperture and wavelength. Single-mode fiber (Single-mode fiber = SMF): only able to transfer a pattern of signal waves, but must be qualified: if I remember that in the materials on the normalized frequency that is called something related to the special needs  of core fine point, it is best wavelength of 3,4 times; so single-mode light from the appearance, more than fine multi-mode fiber; single-mode fiber as a mode of transport only, so there is no modal dispersion.The OS1 Simplex Patch Cord Pigtail fiber end to orange, and transmission distance is 500m, suitable for short distance connectivity. And SM 9/125 Pigtail is the typically single-mode fiber patch cable, with yellow end. The single-mode fiber patch cords have two kinds of wavelength, 1310 nm and 1550 nm, and transmission distance of 10 km and 40 km respectively.
