Abstract: The present invention is an optical splitter module comprising couplers, which have one or more optical connectors attached thereto. The optical splitter module further comprises an adaptor holder for fixing a plurality of optical adaptors in a line and having a height the same as or smaller than that of the optical adaptor, a housing having means for fixing the couplers, and a cover adapted for preventing the coupler from being externally exposed. The height of the optical splitter module is the same as or smaller than the height of the optical adaptor mounted on the adaptor holder. The adaptor holder further comprises a wrinkled portion with a plurality of peaks and gullies alternatively formed in a longitudinal direction. The wrinkled portion has a plurality of adaptor insertion holes for receiving and supporting the optical adaptors. The front edge of the housing has a toothed portion, which corresponds to the peaks and gullies of the wrinkled portion of the adaptor holder.
