What are the usage considerations and differences between single-mode and multimode fiber?

I. The use of single-mode fiber and multimode fiber Note: 1, indoor optical fiber without special instructions, the short-wave optical module using orange multimode fiber, long-wave module using yellow single-mode fiber. This belongs to the line of inertia that, specifically, also depends on the manufacturer's configuration. 2, fiber optic jumper using the material is very delicate, so in the process of using, must not be excessive bending and wrapping, even in the case of a protective cover should also pay attention to, not only easy to damage, but also more importantly will increase the attenuation of the light transmission. 3, fiber optic jumper cable protection: after connecting to do after the dust and grease, otherwise it will damage the Coupling of optical fiber.

-Second. The difference between single-mode fiber and multi-mode fiber: 1, from the role of multi-mode fiber can transmit a variety of modes of light; single-mode fiber can only transmit a mode of light. 2, from the appearance of multi-mode fiber middle core is thicker, single-mode fiber middle core is thinner, just two relative, multi-mode is 50 microns, single-mode is 10 microns. 3, multi-mode optical fiber transmission distance is relatively close, generally only a few kilometers; single-mode fiber transmission distance is much farther, usually can reach tens of times the multi-mode fiber. 4, multi-mode fiber price is more than single-mode fiber price. A few kilometers; single-mode fiber transmission distance is much farther, usually can reach dozens of times the multi-mode fiber. 4, the price of multi-mode fiber than single-mode fiber to be more expensive.
