A optical assembly and a method of reducing interference using the same may be provided. The optical assembly may include an optical cable and an optical transceiver module. The optical transceiver module may include a socket configured to receive the optical cable, an electro-optical transducer configured to generate an optical signal, and an optical lantern. The optical lantern may include an optical prism that may receive the optical signal via a first surface, disperse the optical signal into a plurality of modes of the optical signal, and output the plurality of modes via a second surface. A mirror may reflect the optical signal from a first direction extending between the first surface and the mirror to a second direction extending between the mirror and the second surface. The optical lantern may direct at least one of the plurality of modes of the optical signal into the optical cable.
