ABSTRACT:
In an optical coupler for dividing or combining lights of different wavelengths, at least one wavelength separating filter connector terminal is provided at least one light input and output terminals. The wavelength separating filter connector comprises first and second optical fibers which are in contact with each other by placing an optical wavelength separating filter film between the first and second optical fibers, so that an isolation is large between separated lights.
