摘要： An optical transmission module has a laser diode, a photodiode, a binary-type DOE lens for 1.3 nullm and a DOE lens for 1.55 nullm in a package. An optical fiber is arranged so that its end surface faces the optical transmission module. The laser diode radiates light of wavelength 1.3 nullm. The photodiode receives light of wavelength 1.55 nullm. Both DOE lenses have diffraction action of mutually different diffraction orders for light of the two wavelengths. The optical axis passing from the laser diode to the optical fiber and the optical axis passing from the photodiode to the optical fiber are separated. The optical transmission module is compact and has a small number of components.

摘要： A tunable dispersion compensator whose passband center wavelength changes when the amount of dispersion compensation is changed is suitably adjusted. The relationship between temperature for keeping the center wavelength constant and the amount of dispersion compensation is stored in advance. After controlling the amount of dispersion compensation to achieve best or optimum transmission quality, the amount of dispersion compensation is converted into temperature in accordance with the stored relationship and, based on that, the temperature is controlled to keep the center wavelength constant.

摘要： An optical transmission system includes a transmitter unit, a receiver unit, and an optical transmission path interconnecting the transmitter and receiver units. A plurality of optical repeaters are situated along the transmission path. Adjacent ones of the repeaters are interconnected by transmission spans that collectively constitute a majority of the optical transmission path. Each of the transmission spans comprises substantially identical lengths of cabled optical fiber having substantially identical prescribed path average dispersions. At least one adjustable dispersion trimming element is located in the optical repeater and optically couples one of the transmission spans to an optical amplifier located in the repeater. The adjustable dispersion trimming element has an adjustable path average dispersion selected such that a total path average dispersion of the transmission span to which it is coupled plus the adjustable dispersion trimming element has a desired value.
