Abstract: According to the requirements of multi-service integrated access, multi network cooperative load and multi-service security isolated transmission in power communication access network, combined with the construction status of power communication access network, a power multi-service security access solution based on time and wavelength division multiplexed passive optical network(TWDM-PON) technology is proposed. By analyzing the shortcomings of existing communication technologies in power communication access network, this paper studies the network architecture of TWDM-PON technology and its adaptability to multi-service load. Proposing a dynamic resource scheduling mechanism to realize multi-service unified bearer and an isolation technology based on switching and storage resources, and builds an experimental environment to verify and analyze the key performance indicators of TWDM-PON in the application of power communication access network,and explores a feasible communication network construction mode for the unified load of power multi service.
