An optical interconnect device is provided that includes a first vertical cavity of surface emitting laser (VCSEL), connected in parallel with a second VCSEL, an optical coupler that is configured to direct the light output from the first VCSEL and the second VCSEL to a single optical fiber, where a common connection of each VCSEL is controlled using a MOSFET/inverter, where in normal operation only one of the first VCSEL or the second VCSEL is enabled, where a common connection of each VCSEL is not directly connected to a ground, and a microcontroller that is configured to switch output from the first VCSEL to the second VCSEL in the event of failure by the first VCSEL, where a failure of the first VCSEL does not result a communication in link failure.
