Common knowledge of CWDM and DWDM
11/9/15  |  Technical Article  |

With the Internet, high-speed IP data traffic growth, resulting in demand for transmission bandwidth is increasing. Though DWDM (Dense Wavelength Division Multiplexing) technology as the most effective way to solve the line bandwidth expansion, but CWDM (coarse wavelength division multiplexing) technology over DWDM system has advantages in cost and maintainability.

How fiber work?
11/4/15  |  Technical Article  |

Communication with the fiber from the outer cover of plastic protective layer composed of glass as thin as a hair. Glass substantially consists of two parts: the core diameter of 9 to 62.5μm, the cover having a diameter of 125μm low refractive index of a glass material. Although according to the materials used and the dimensions of different points there are other types of fiber, but mentioned here are the most common that several. Light in the core portion of the fiber to the "total internal reflection" mode for transmission, but also refers to an end after the light enters the fiber, at the interface between the core and the cladding reflected back and forth, and then transferred to the other end of the fiber. Core diameter of 62.5μm, cladding outer diameter of 125μm fiber called 62.5/125μm light.
