A light path boss is formed between the two vertical grooves and on the substrate and lens bosses are formed outside the two vertical grooves and on the substrate. Light-guiding grooves successively connected in an end-to-end manner are arranged on the light path boss and between the two grooves and are in a broken-line shape integrally. A plurality of openings at equal intervals are formed on the sidewalls of the two grooves by the light-guiding grooves. The openings comprise a light inlet at the top and a plurality of light outlets under the light inlet. Optical filters are disposed at the light outlets and on the light path boss. Lens grooves along the light-guiding groove direction are disposed on the lens bosses and outside of optical filters. Condensing lenses are disposed in the lens grooves. Light signals can be condensed when leaving the central processor and fiber reception and collimation operation are simplified. The lens bosses and the light path boss are arranged on a same substrate such that a relative position relation between the condensing lenses and the optical filters can be maintained accurate and fixed and light path loss is prevented.
