Abstract
A method and an apparatus are provided for launching light into an entrance facet of a multimode optical fiber (MMF) of an optical link in a way that excites one or more higher-order Hermite Gaussian (HMG) mode groups in the MMF. Exciting higher-order HMG mode groups in the MMF increases the bandwidth of the link while also providing reduced modal noise. In addition, selectively exciting one or more higher-order HMG mode groups in the MMF ensures that the launch will provide desirable results even in cases where the connector that connects the end of the MMF to the optical transceiver or transmitter is offset with respect to the receptacle of the optical transceiver or transmitter. This feature allows for greater manufacturing tolerances when manufacturing the connectors and receptacles because precise alignment between them is not critical to achieving a successful launch.
