points in the OS1 Simplex Patch Cord diameter

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.Single-mode single-mode fiber can transmit the signal, while multi-mode multi-mode fiber can transmit signals, multi-mode OS1 Simplex Patch Cord As the name suggests is the ability to disseminate a variety of modes of electromagnetic waves (light waves here, of course) of the fiber; transfer due to multiple modes, so there is a great dispersion between modes, the information can be transmitted smaller capacity; large core multimode fiber, usually 50um, numerical aperture of about  multi-mode fiber with in small volume, short-range system, OS1 Simplex Patch Cord for the trunk, large capacity, long-distance single-mode fiber core diameter of system is generally , and is  multimode. Single-mode and multimode wavelengths are relatively specific terms, the same fiber at different wavelengths may also be multi-mode single-mode.
