Abstract
An example embodiment includes a system for communicating an optical signal. The system includes an optical transmitter and an optical receiver. The optical transmitter includes one or more lasers configured to produce a light signal and a transmitter optical sub assembly (TOSA) receptacle. The TOSA receptacle optically couples the lasers to an optical fiber and launches a quasi-multimode optical signal (quasi-MM signal) that includes at least one lower order mode optical signal and at least one higher order mode optical signal onto the optical fiber. The optical receiver is connected to the optical fiber via a receiver optical sub assembly (ROSA) receptacle. The optical receiver is configured to receive the quasi-MM signal and to substantially block the at least one higher order mode optical signal.
