Market research firm IC Insights released an analysis of R&D trends in its latest 2022 McClean Report quarterly update, saying that about 56% of global semiconductor industry R&D spending in 2021 will come from companies headquartered in the Americas region, These companies are largely based in the United States, with a large percentage coming from Intel (19%). As shown in the chart below, semiconductor R&D spending by companies in the Asia-Pacific region (including foundries, fabless and IDM) will exceed 29% of the global total in 2021, followed by European companies with about 8% and Japan with nearly 7%. In 2011, chip suppliers in the Americas accounted for about 55 percent of global semiconductor R&D spending, compared with 18 percent in the Asia-Pacific region (including China). Nanjing Hecho Technology has strong optical fiber R&D and production capabilities, and can provide customized services for various Optical Fiber Bundles for different industries and usage needs to flexibly meet the differentiated needs of different customers. In addition, high-brightness LED Light Sources and Halogen Light Sources for use with optical fibers are available.

The loss is mainly caused by the scattering and escape of light generated by the fiber during bending.When the light is transmitted in a curved fiber, part of the light will escape from the fiber due to the changing propagation speed and direction of the light in the medium, thus causing the loss of the optical signal.In addition, the propagation of light in the optical fiber is through full reflection, and at the bend, the degree of incidence angle of light may exceed the critical angle of full reflection, resulting in scattering phenomenon, which will also cause the loss of optical signal.The size of the macrobending loss is affected by many factors, including the bending radius, the type and material of the fiber, and the outer coating of the fiber. A smaller bending radius will increase the scattering and escape of light, resulting in increased macrobending loss.The special outer coating can reduce the scattering and escape of light, thus reducing the macrobending loss.
