The single mode in the light module actually only refers to the type of fiber. The single -mode light module is a light module used with single -mode optical fiber. It uses LD or LEDs with narrow LEDs as a light source, which can transmit very high bandwidth data signals, so the transmission distance is far away. The logo on the single -mode optical module is "SM", the fiber is yellow, and the wavelengths are mainly near 1310Nm and 1550Nm windows.
The bandwidth potential of the single mode in the single -mode light module makes it the best choice for high -speed and long -distance data transmission. It is mostly used for long -distance transmission such as LR and ER/ZR. The transmission rate is relatively high. , Construction of Urban Division Network, etc. The application fields are widely used, including telecommunications, cable television, railway, military, financial securities, customs, civil aviation, sea transportation, electric power, water conservancy and oil fields and other broadband data networks and high -reliability data transmission or establishing IP data transmission special networks It is the most ideal application equipment for Broadband Campus Network, Broadband Cable TV Network and Intelligent Broadband Community Fiber to Building and Fiber -to -Households.
Overview of multi -mode light module
The optical module that can obtain the optimal transmission characteristics with multi -mode optical fiber is called a multi -mode light module that can obtain the optimal transmission characteristics. It can transmit light of multiple modes. The appearance is shown in the figure below. The multi -mode light module limits the frequency of transmitting digital signals due to large scattering of the modulus, so it is generally used for short -range transmission.
