摘要：
An optical transmission system transmits a Radio Frequency (RF) signal by a frequency division multiplexing method. The optical transmission system includes a Transmitter Optical SubAssembly (TOSA), an optical fiber, and a Receiver Optical SubAssembly (ROSA). The TOSA includes a surface emitting laser diode configured to be capable of emitting light at output of 0.8 mW or more. In the optical transmission system including the surface emitting laser diode, a noise index obtained by a measurement method including a predetermined step is 10.0 dBμV or less.
