Abstract: An optical communication apparatus in which bidirectional communication may be made over a sole optical fiber. A light emitting device (132) radiates light through an optical system (133) to an optical fiber (76). The light transmitted from the optical fiber (76) is received over optical system (133) by a light receiving device (136). In the optical system (133), such a relationship S - 2QN ≥ M > S/2Q - N is set, where M is the light volume of the stray light emitted, Q is the value of a Q-value representing the communication quality as required, S is the light volume of a received signal from a communication partner and N is the sum total of the Gaussian noise.

Abstract: An optical communication apparatus using a single optical fiber to effect a two-way communication at the same time. A light emitting element (132) emits its generated light through an optical system (133) to an optical fiber (76). A light having been transmitted through the optical fiber (76) is received by a light receiving element (136) via the optical system (133). The optical system (133) is set such that the value of the light amount M of stray light is given as follows: S - 2QN ≥ M > S / 2Q - N where Q is the value of the Q value representing a required communication quality, S is the light amount of a received signal from the other end of communication, and N is the total sum of Gaussian noise.

Abstract: A transmitting apparatus includes a rate adjusting unit, a changing unit, an output unit, and a transmitting unit. The rate adjusting unit adjusts a transmission rate of transmitting data. The changing unit changes a size of a buffer for temporarily storing the data, on the basis of the transmission rate. The output unit reads out the data stored in the buffer and outputs the data to a transmitting unit. The transmitting unit transmits the data output by the output unit.
