摘要： The present invention is an SSFBG with which there are few restrictions on the code that can be set and the overall length of which is short. This SSFBG has four unit FBGs the Bragg reflection wavelengths of which are λ1, λ2, λ3, and λ4 disposed with a part where the unit FBGs overlap one another in the waveguide direction of the optical fiber. The left end of the horizontal axis corresponds to the position of the I/O terminal of the SSFBG and the right end of the horizontal axis corresponds to the terminal on the opposite side from the I/O terminal of the SSFBG. The Bragg reflection wavelengths λ1, λ2, λ3, and λ4 of the four unit FBGs are λ1=1543.28 nm, λ2=1543.60 nm, λ3=1543.92 nm, and λ4=1544.24 nm respectively. Codes (λ1, λ2, λ3, and λ4) used in the time-spreading/wavelength hopping system are established for the SSFBG by disposing the four unit FBGs at equal intervals such that the interval therebetween is 12.8 mm.

摘要： An object of the present invention is to adjust the operating wavelength of a decoder, in order to coordinate the operating characteristics of an encoder and the decoder. To this end, an optical code division multiplex transmission device of the present invention comprises a second SSFBG in the decoder, and has a mechanism to perform adjustment (phase adjustment step) of the fixation portion interval L which is the interval between a first and second fixation portions fixing in place the second SSFBG, such that the extent of the eye opening of optical pulses output from the second SSFBG is maximum. The extent of the eye opening is measured using a correlation waveform monitor, and the measurement data is sent to the wavelength control portion. A signal is sent from the wavelength control portion to the movement control portion to set the fixation portion interval L, based on data relating to the extent of the eye opening sent from the correlation waveform monitor.
