With the development of geophysical prospecting collection technology , the advanced acquisition technical requirements for seismic instrument has real-time ability stronger, higher collection efficiency, higher stability and reliability, etc. In order to solve the seismic instrument real-time ability and system synchronization problems , we design a PCI -E optical fiber interface card, the function of the optical fiber in this card and its position in the whole system are introduced. We analyze the optical fiber card and the host interface, data processing and the design of the GPS synchronization function. Through field exploration and production application, the results show that optical fiber card real-time capability is strong, and has a good reliability and stability.
