The 1×2 couple provided by yingda utilize fused biconical tapering technology, the core materials include a quartz substrate, optical fiber, and stainless steel tubing. In optical communication systems, it is used for the distribution and coupling of optical signals and is an important passive component in fiber optic networks, CATV network, fiber optic sensors.
All fiber optic tapered couplers are packaged and shipped only after undergoing rigorous testing. If the test data is unsatisfactory, the product is returned to the production line for rework. All 1×2 FBT fiber coupler manufacturing processes are certified under the strict ISO9001 quality management system. Customers can purchase with confidence.
