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.

Abstract: A digital signal cross-connect module with output and input jack systems formed on the front aspects of its housing, the output jack system comprising an output jack, a cross-connect output jack and an output signal monitoring jack, the input jack system comprising an input jack, a cross-connect input jack and an input signal monitoring jack, BNC input and output connectors formed on the rear of the housing, BNC cross-connect input and output connectors formed on another aspect of the rear of the housing and arranged in parallel with the BNC input and output connectors in a staggered relationship, first through fourth shielding cables respectively and electrically connecting the output jack and the BNC output jack, the cross-connect output jack and the BNC cross-connect output connector, the input jack and the BNC input jack, and the cross-connect input jack and the BNC cross-connect input connector.

Abstract: The present invention is an optical splitter module having couplers splitting signals transmitted through cables to which one or more optical connectors are attached. The optical splitter module further comprises an adaptor holder having a front surface and a rear surface. The optical splitter module maintains a plurality of optical adaptors therethrough such that the optical adaptors are exposed to the outside of the module. The optical splitter module further comprises a housing for maintaining couplers therein and which has a bottom and sidewalls upwardly extending from the bottom, and a cover positioned on the sidewalls to close an upper portion of the housing. The bottom of the housing is provided with a contact portion engaged to the rear surface of the adaptor holder. The cover further comprises a contact portion engaged with the rear surface of the adaptor holder.
