你们的光端机用什么光纤? 答:我们来回答这个问题可能不是最专业的,但还是给你一些参考: 1.单模光纤对特定的波长传输一个模式.而多模光纤可以传输若干个模式. 2.单模光纤的纤芯较小(一般为9μm左右),多模光纤的纤芯由较粗(50或62.5μm) 3.单模光纤的色散较小,传输频率高.而多模光纤色散较大,传输频率低 4....
Single-mode : The fiber core size of thesingle-mode fiberis 9/125 um,and compared with multimode fiber, it is with the features of unlimited bandwidth and lower loss. The single-mode optical transceiver used for the long-distance transmission, and sometimes up to 150-200 km. Using LD or...

At present, there are two different types of optical fiber, single-mode fiber and multi-mode fiber (so-called mode), which means a beam of light entering the fiber at a certain angle. Multimode fiber is generally used in the same office building or in a relatively close distance within ...
