In this blog, ETU-Link will introduce OM5 optical fiber patch cord. In order to distinguish different optical fiber patch cord, different colors outer sheath are used.For non-military purposes, single mode optical fibers generally use yellow outer sheath. In the multimode optical fiber, OM1 and OM2 are orange, OM3 and OM4 are aqua blue, and OM5 is aqua green. After understanding the color appearan...

MM fiber Concept MM fiber is a fiber that transmits multiple modes at a given working wavelength. When the geometric size of the fiber is much larger than the wavelength of the light wave, there will be dozens or even hundreds of propagation modes in the fiber. Different propagation modes have different propagation velocities and phases, resulting in time delay and widening of optical pulses ...
