R&D center
We have the professional R&D group in which each employee is highly trained and the processing method for manufacturing lensed fiber is the most advanced in the world, meanwhile, we holds independent intellectual property protection .We can supply a variety of different lensed fiber, that includes oblique wedge-shape, wedge-shape, cone-shape and spherical. Metallic coating and FC packaging can also be applied. The physical dimensions of the lensed fiber are controllable with more than 80 percent coupling efficiency possible. The physical dimensions are controllable with more than 80 percent coupling efficiency possible.The equipment of R&D center is uniquely designed in-house, enabling the company to improve on any design to satisfy the customers' requirements all over the world.There are 32 work stations in lensed fiber workshop , with a monthly production capacity of nearly 50,000 pieces.
