Abstract: A splitter includes an optical input section, N optical branch sections, and at least (N−1) optical filter structures. Each optical filter structure reflects an optical signal of one wavelength. The at least (N−1) optical filter structures include a special optical filter structure and at least (N−3) common optical filter structures, and a wavelength of an optical signal reflected by each of the common optical filter structures is a common wavelength. A wavelength of an optical signal reflected by a first/second special optical filter structure is a first/second special wavelength. At least (N−3) common wavelengths constitute an arithmetic sequence, a difference between the first special wavelength and a largest common wavelength is greater than a tolerance of the arithmetic sequence, and a difference between the second special wavelength and a smallest common wavelength is greater than the tolerance of the arithmetic sequence.

Abstract: The present invention provides an optical splitter and a system, including: an optical divider, a ribbon fiber, and tributary fibers, where the optical divider is configured to divide an input optical signal into at least two optical signals for output; one end of the ribbon fiber is connected to the optical divider, and the other end of the ribbon fiber is connected to the tributary fibers, where a grating array is disposed on the ribbon fiber; and the grating array includes at least two Bragg gratings, different Bragg gratings correspond to different tributary lines of the optical divider, and the number of Bragg gratings included in the grating array is the same as the number of optical signals output by the optical divider; which solves a problem that additional connection loss is increased because an existing splitter needs to be connected to each link fiber by using an optical connector.
