As shown in fig. 7, an optical communication apparatus a and an optical communication apparatus B having the same configuration are connected via transmission paths (optical fibers) 1 and 2. The optical communication device a may be regarded as a master optical communication device, and the optical communication device B may be regarded as a slave optical communication device. The optical communication devices a and B are equipped with interfaces for data transmission and reception, but are not equipped with a dedicated interface for adjusting the dispersion amount of the transmission path. In fig. 7, the O/E converter 11 receives an optical signal transmitted from the opposite device and performs a process of converting the optical signal into an electrical signal. The O/E converter 11 constitutes an optical signal receiving unit. The frame termination matching unit (frame termination) 12 performs termination matching (terminations) on the data frame (the data frame generated by the frame generation unit 19 of the opposite device) based on the electric signal output from the O/E conversion unit 11.
The optical input interruption detection unit 13 monitors the electrical signal output from the O/E conversion unit 11, and performs a process of detecting an input interruption of the optical signal received from the O/E conversion unit 11. The optical input interruption detecting unit 13 monitors the electrical signal output from the O/E converting unit 11, and when detecting an interruption of the input of the optical signal corresponding to the dispersion amount adjustment request pattern (pattern) transmitted from the opposing device, performs a process of outputting a detection signal of the dispersion amount adjustment request pattern to the dispersion compensator 21. The O/E converter 11 and the optical input interruption detector 13 constitute optical input interruption detection means and dispersion amount adjustment request receiving means. The frame loss detection unit 14 monitors the data frame that has been subjected to the termination matching by the frame termination matching unit 12, and performs a process of detecting a frame loss of the data frame. Further, the frame end matching unit 12 and the frame loss detection unit 14 constitute frame loss detection means. The pattern generation unit 15 generates a dispersion amount adjustment request pattern when a frame loss is detected by the frame loss detection unit 14 in a state where the optical input interruption detection unit 13 does not detect an input interruption of an optical signal, and performs a process of repeatedly outputting the dispersion amount adjustment request pattern to the E/O conversion unit 16 until the frame loss is not detected. However, since the pattern generation unit 15 transmits the optical signal in the dispersion amount adjustment request pattern at a bit rate lower than the bit rate at which the optical signal of the data frame is transmitted (for example, at a transmission rate of 1/4 or less of the transmission rate of the data frame), the pattern generation unit generates the dispersion amount adjustment request pattern in which the E/O conversion unit 16 turns ON/OFF the light at a frequency of about several tens to several hundreds Mb/s. Upon receiving the electrical signal indicating the data frame generated by the frame generation unit 19, the E/O conversion unit 16 converts the electrical signal into an optical signal and transmits the optical signal to the transmission line 1 (or the transmission line 2), and upon receiving the dispersion amount adjustment request pattern from the pattern generation unit 15, performs a process of transmitting the optical signal corresponding to the dispersion amount adjustment request pattern to the transmission line 1 (or the transmission line 2) by turning ON/OFF the light in accordance with the dispersion amount adjustment request pattern. Further, the pattern generation unit 15 and the E/O conversion unit 16 constitute dispersion amount adjustment request transmission means. The own device error rate monitoring unit 17 monitors the data frame end-matched by the frame end matching unit 12, and performs a process of detecting the error rate of the own device. The error rate insertion control unit 18 performs a process of outputting an instruction to the frame rate generation unit 19 to insert the error rate of the own device detected by the own device error rate monitoring unit 17 into an overhead area (an area open to the user) in the data frame. The frame rate generating unit 19 generates a data frame including data to be transmitted to the opposite device, and performs a process of inserting the error rate of the own device into an overhead area in the data frame under the instruction of the error rate insertion control unit 18. The counter device error rate monitoring unit 20 performs a process of acquiring the error rate of the counter device from the overhead area in the data frame end-matched by the frame end matching unit 12. Upon receiving the detection signal of the dispersion amount adjustment request mode from the optical input interruption detection unit 13, the dispersion compensator 21 performs a process of adjusting the dispersion amount of the transmission line 1 (or the transmission line 2) by changing the dispersion value given to the transmission line 1 (or the transmission line 2) (for example, changing the dispersion value from the minimum value to the maximum value thereof gradually to increase the dispersion value within the dispersion possible range). That is, when the detection signal of the dispersion amount adjustment request mode is output from the optical input interruption detection unit 13, the dispersion compensator 21 starts coarse adjustment of the dispersion amount of the transmission line 1 (or the transmission line 2), and when the detection signal of the dispersion amount adjustment request mode is no longer output from the optical output intensity detection unit 13, fine adjustment of the dispersion amount of the transmission line 1 (or the transmission line 2) is performed so that the error rate of the opposing device obtained by the opposing device error rate monitoring unit 20 becomes minimum. Furthermore, the phase device error rate monitoring unit 20 and the dispersion compensator 21 constitute dispersion amount adjusting means. In the example of fig. 7, it is assumed that the O/E conversion unit 11, the frame termination matching unit 12, the optical input interruption detection unit 13, the dropped frame detection unit 14, the pattern generation unit 15, the E/O conversion unit 16, the self-apparatus error rate monitoring unit 17, the error rate insertion control unit 18, the frame rate generation unit 19, the opposite-apparatus error rate monitoring unit 20, and the dispersion compensator 21, which are components of the optical communication apparatus, are each configured by dedicated hardware (for example, a semiconductor integrated circuit on which a CPU is mounted, a one-chip microcomputer, or the like), but when the optical communication apparatus is configured by a computer or the like, the O/E conversion unit 11, the frame termination matching unit 12, the optical input interruption detection unit 13, the dropped frame detection unit 14, the pattern generation unit 15, the E/O conversion unit 16, the self-apparatus error rate monitoring unit 17, and the error rate insertion control unit 18, which are described therein, may be configured by the computer or the like, All or a part of the programs of the processing contents of the frame rate generating unit 19, the counter device error rate monitoring unit 20, and the dispersion compensator 21 are stored in a memory of a computer, and a CPU of the computer executes the programs stored in the memory
