The optical transmitter and receiver of the invention includes: a variable dispersion compensator that performs wavelength dispersion compensation on an optical signal of a differential M-phase modulation format input from a transmission path; an optical amplifier that compensates an optical loss in the variable dispersion compensator; a delay interferometer that delays and interference processes the optical signal output from the optical amplifier; and a photoelectric conversion circuit that photoelectric converts the output light from the delay interferometer to generate a demodulated electric signal. The output level of the optical amplifier is decreased at the time of start up to deteriorate the OSNR of the optical signal input to the photoelectric conversion circuit, to thereby realize a state in which an error occurs more easily, and then optimization control of the variable dispersion compensator and the delay interferometer is started. As a result optimization of the dispersion compensation amount and the phase control amount in the optical receiver corresponding to the differential M-phase modulation format can be performed in a short time.

Optical receiver and controlling method thereof, and optical transmission system

An optical signal, which is a low-speed signal superimposed on a high-speed phase modulated optical signal by intensity modulation, is used. In an optical receiver apparatus, a received signal is split, and one of the split signals is O/E converted and low frequency component alone is extracted via a filter. A clock is extracted from low-frequency component by CDR, and is compared with a preset frequency. Using the frequency difference obtained, dispersion compensation is performed with low accuracy. Next, the amount of phase control of the delay interferometeris adjusted so that the amplitude of the electrical signal is maximized. An error rate is measured, and fine adjustment is performed to improve the error rate.

A LAN signal transmission method and a transmission apparatus using the method are disclosed. A first transmission apparatus extracts only a data section of a LAN signal that is received, and accommodates the data section in a digital wrapper signal. Link information between a first LAN apparatus is accommodated in the overhead of the digital wrapper signal, and the digital wrapper signal is transmitted to a second transmission apparatus. The second transmission apparatus extracts the data section of the digital wrapper signal and the link information from the overhead of the digital wrapper signal that is received. The LAN signal that contains the data section and the link information is constituted, and transmitted to a second LAN apparatus. If the extracted link information indicates 'link down', the LAN signal to the second LAN apparatus is shut down, and the link information concerning the second LAN apparatus indicating 'link down' is masked, the link information being transmitted to the first LAN apparatus.
