Modern multi-spectral sky survey requires the use of greater quantity and smaller size of the fiber positioner. This paper presents a high-density integrated optical focal plane positioning system, which includes 150 groups fiber positioning module and a 1 meter diameter honeycomb-shaped focal plane framework in that have about 150 hexagonal hole. Each module has a pedestal includes 37 holes and 37 fiber positioner of 11.8 mm diameter. 37 fiber positioner integrated can greatly reduce the difficulty of the design and installation. The modular structure also facilitates maintenance and replacement in the field of telescope, and greatly reduce the difficulty of the drive system design. Numerical simulation results show that: the honeycomb-shaped focal plane framework whose thickness is 100mm and who is in a variety of working positions and load conditions, its maximum deformation is about 0.02mm. This meet the needs of the general astronomical telescopes. The positioning accuracy of test 12mm diameter fiber positioner is about 0.04 mm, and it is expected to reach 0.01mm if have the closed-loop control.
