Description
[technical field]
The present invention relates to the plastic optical fiber prefabricated stick technical field, specifically a kind of manufacture method of visible light curing gradient type plastic optical fiber prefabricated stick.
[background technology]
Along with the development of information industry, need the information transmitted amount increasing, in these information, comprise the exigent information of real-time such as voice, image, this message capacity to communication system has proposed very high requirement.Quartzy single-mode fiber has been brought into play important effect with its good transmission characteristic in long distance, jumbo communication system.Since the eighties in last century, personal computer pours in office, laboratory, factory and family, and the demand that intercomputer is shared information has promoted networks development.The user increases severely to the demand of communication bandwidth, but also need connect into intensive network in short distance.Because the core diameter of silica fibre is very thin, single mode 10 μ m, multimode 50～62.5 μ m, make silica fibre coupling with is connected difficultly, the cost of coupler and connector is very high.Therefore, be in user side and the LAN at the end of communication system, just problem has been arranged if make transmission medium with silica fibre again, because in user side and LAN, between optical fiber and the optical fiber, need to be connected between optical fiber and the transceiver, this can increase considerably cost.In order to solve the bottleneck problem of last kilometer of fiber optic communication bandwidth, people begin to develop gradient plastic fibers.Transmission medium as user side and local hilllock.Plastic optical fiber has the advantage of a lot of uniquenesses: cheap for manufacturing cost; Easier termination, coupling, its core diameter is approximately 1mm; The termination cost is few, and the connector of polymer optical fiber can use cheap moulding; Have fabulous pliability, light weight, and insensitive to vibrating, more suitable in the occasion that needs fibre-optical bending than silica fibre, be easy to processing and be fit to various wire laying modes.Therefore, plastic optical fiber has become one of selected materials that following optical fiber registers one's residence.
The heat cure mode is adopted in the manufacturing of gradient type plastic optical fiber prefabricated stick mostly, and hardening time is long, and air bubble problem is difficult for solving.China patent CN1529189A, CN1415985 adopt the ultra-violet curing coating technology, shortened hardening time greatly, but only be used for thin layer.Japan AGC Co., Ltd. discloses the manufacture method of refractive index-distributed type plastic optical fiber at Chinese patents CN1219244A, this method be by the cylindric formed body that forms than low-index material be the basis, the side has two-layer cylindric mother metal at least inside and outside being formed by the higher layer shape material of refractive index by rotary forming within it, but this method is to adopt heat cure to be shaped, resin binder all is a fluorinated polymer, but hardening time is long, need 10 hours, and bubble is difficult for removing, quality be cannot say for sure to demonstrate,prove, and with high costs.
