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 dB&#x3bc;V or less.

Optical transmission system and electro-optical conversion device

Provided is an optical fiber cable which allows for high-quality signal transmission in short-distance transmission. The optical fiber cable is designed for use in optical communication based on transmitting an optical beam from a light-emitting device, to a light-receiving device. The optical fiber cable has: a proximal end which is one end thereof on the side of the light-emitting device, and a distal end which is the other end thereof on the side of the light-receiving device, wherein an optical beam returning from the side of the distal end toward the side of the light-emitting device has an Mfactor of 1.7 or more; and a length of 50 m or less.
