Data transmission system using optical fiber

摘要

A data transmission system using an optical fiber includes an optical fiber, a first light-emitting device, a second light-emitting device, a first photo-detecting device and a second photo-detecting device. Each of the first light-emitting device and the second light-emitting device is optically coupled to the input facet of the optical fiber, respectively. Each of the first photo-detecting device and the second photo-detecting device is optically coupled to the output facet of the optical fiber, respectively. In particular, the first light-emitting device and the second light-emitting device are packaged into a first optical subassembly, and the first photo-detecting device and the second photo-detecting device are packaged into a second optical subassembly.
