摘要： An optical link module connection system for connecting an optical fiber to an optical link module that performs conversion between an electrical signal and an optical signal. The system is aimed at reduction of the manufacturing cost of printed circuit boards containing those fiber-optic products by allowing an automated soldering process to be applied thereto. The system will also facilitate the product handling as well as storage and improve the board space utilization by shortening the length of the optical fiber. While optoelectronic conversion means comprises a first ferrule, coupling means consists of a second ferrule, a split sleeve, etc. The first ferrule is inserted into the split sleeve in the coupling means so as to contact the second ferrule, thus completing an optical path between a first optical fiber and a second optical fiber. The optoelectronic conversion means will be soldered to a printed circuit board before being joined to the coupling means. That is, when soldering the printed circuit board, the second optical fiber having only a poor heat resistance is not yet mounted on the board, thus allowing automated soldering equipment to be used for the process.

摘要： An optical transmission device improved in quality and reliability of OADM function and permitting configuration of highly-flexible, economical OADM networks. A wavelength tunable filter variably selects a wavelength according to a control frequency. A filter controller applies the control frequency to the filter while scanning wavelength over an entire signal bandwidth, to detect, from a reference wavelength monitor signal supplied thereto, a reference control frequency which permits the filter to select a reference wavelength and according to which wavelength is matched. On receiving a wavelength selection request, the controller obtains a target control frequency from the reference control frequency and the position of a target wavelength relative to the reference wavelength, and applies the obtained frequency to the filter. A reference wavelength filter transmits the reference wavelength therethrough. A light-receiving element monitors the transmitted reference wavelength to generate the monitor signal.
