Problems solved by technology
The optical fiber EPON communication method has been widely recognized for its advantages of high speed, low cost, and flexible networking, and has become the main communication method for the construction of distribution automation communication systems. Because the optical fiber EPON communication method needs to lay optical cables, but in the urban distribution network Among them, there are still a large number of areas or sites where it is difficult or even impossible to lay optical cables, and it is impossible to realize the smart grid power distribution automation communication system in the form of optical fiber EPON communication
