摘要： PURPOSE:To realize the connector for large-output laser light which never generates heat by forming gap parts at the outer peripheries of the end parts of a 1st and a 2nd optical fiber and also providing a fine gap between both the fiber end surfaces. CONSTITUTION:The connector consists of ferrules 3 and 4 which hold the 1st and 2nd optical fibers 1 and 2, a cylindrical adapter 5, fitting bodies 6 and 7 which are fitted to the ferrules 3 and 4, and cap nuts 8 and 9. While the optical fibers 1 and 2 are held, the gap parts 47 and 48 are provided at the outer peripheries of the end parts of the optical fibers 1 and 2 and the fine gap A of 2 - 100mum is formed between both the fiber end surfaces 20 and 21. Consequently, the end surfaces 20 and 21 never contact each other, heat generation is hardly caused, and no end surface damage occurs. Further, the transmissivity does not decrease greatly and the connector is used suitably for a large-output laser.
