In the implementation of network engineering, optical fiber can be divided into single-mode optical fiber and multi-mode optical fiber. Then what are their respective features?The first thing to understand is that both single-mode and multi-mode optical fibers are used for high-quality transmission of network signals over long distances.   Today, the Inline Closure manufacturers analyze the respective features of single-mode and multi-mode fiber   So the distinction between single mode and multi-mode is based on the way light travels within it;Light travels along a straight line in a single-mode fiber, without reflection, so it travels very far.Multimode fiber can carry multichannel optical signal transmission.   Second, from the outside light, the most common method of resolution is;Yellow fiber lines are typically single-mode, and orange or gray fiber lines are multimode.The difference between the two cable cores is that the size of multi-mode cable cores is 50.0 micron and 62.5 micron.And a single module is 9.0 micron.   Third, both single-mode fiber and multi-mode fiber have LC interface, so in addition, fiber still has very rich interface options.Operators inside the fiber distribution board inside the application of FC interface. And the common ST interface of FTTB.The most commonly used is the LC interface, which is much smaller than all other interfaces.More ports are accommodated in the fixed unit area of the box switch.The light jumper of two LC together is called DLC.Another small interface like LC, but more commonly used for fiber to the desktop, is MTRJ, which puts the usual double fiber in and out of one port.
