According to one embodiment, an optical link includes a case, an optical unit, a plate spring and a shutter. The case is provided with a plug-guided portion and a hole. The optical unit is operable to optically couple to the optical fiber. The plate spring has a hook at one end, the one end internally contacting with the hole and the hook being hooked to the case. The shutter is provided in the plug-guided portion. The shutter is rotating when the plug is inserted, and is turning into an opened state so as to couple the optical unit to the optical fiber while bending the plate spring. The shutter is turning into a closed state due to elastic bending stress of the plate spring when the plug is pulled out, and is blocking an optical path between the optical unit and the optical fiber.
