A flexible spectrum allocation scheme for the hybrid satellite network of laser and microwave is proposed, and a node structure of routing and spectrum allocation is designed based on optical frequency comb. A proof-of-concept experimental system is established and the test results indicate that the proposed system can realize spectrum shifting and flexible bandwidth allocation dynamically. The bit-error rate of recovered baseband data is less than 10 −9 after the signals of the laser and microwave links pass through the node. The proposed scheme can solve the problem of low spectrum utilization due to dynamic services in satellite networks, and is significantly promising for the future hybrid networks of laser and microwave.
