We offer various types of optical fiber preform products such as the low water peak G.652.D optical fiber preform, bend insensitive G.657 optical fiber preform, and other special optical fiber preforms. We have introduced vapor axial deposition (VAD) and outside vapor deposition (OVD) process technologies for fiber preform manufacturing. These technologies can achieve productivity up to 600 tons. It also comes fully equipped with a VAD deposition tower, a VAD sintering tower, VAD annealing equipment, a OVD deposition tower, a OVD sintering tower, OVD annealing equipment and other intelligent sensing equipment. As a result, we are capable of realizing the intelligent management of manufacturing workshops. Currently, we have obtained the ISO9001-2015 certificate of quality management systems.
