Abstract: Disclosed are optical ports and devices having a minimalist footprint. Specifically, the optical ports and devices have a footprint where the optical elements are exposed at a frame of the device. Additionally, a frame of the device provides a portion of the mating surface for engaging a complimentary optical plug during mating with the optical port on the device. This minimalist footprint advantageously allows for a smaller portion of the optical port to be exposed to the environment and subject to damage and/or wear. Further, the optical port provides a clean and sleek optical port on the device with a relatively small surface that may be cleaned or wiped by the user as necessary.
