Claim Text:
1. A system for communicating an optical signal, the system comprising: an optical transmitter including one or more lasers configured to produce a light signal and a transmitter optical sub assembly (TOSA) receptacle, wherein 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; and an optical receiver connected to the optical fiber via a receiver optical sub assembly (ROSA) receptacle, wherein the optical receiver is configured to receive the quasi-MM signal and to substantially block the at least one higher order mode optical signal, wherein the at least one lower order mode optical signal and the at least one higher order mode optical signal included in the quasi-MM signal are at least partially controlled by a receptacle length of the TOSA receptacle and a core diameter of the TOSA receptacle.
