Abstract: A ferrule includes a ferrule matrix, an optical fiber, and a dielectric reflective film. The optical fiber is disposed in an accommodating through hole of the ferrule matrix, and the dielectric reflective film covers an optical transmission surface of the optical fiber and a surface that is of the ferrule matrix and that faces a matching ferrule. The dielectric reflective film has a through hole, such that the dielectric reflective film does not shield a main optical path area of the optical transmission surface of the optical fiber. A reflective band of the dielectric reflective film includes at least a part of a communication band of the optical fiber. In this way, when light from the matching ferrule is transmitted to the ferrule matrix and the optical fiber, the dielectric reflective film reflects the light.

Abstract: A storage device and a storage device operation method are provided. The storage device has a processing capability for a first communications protocol and a processing capability for a second communications protocol. The method includes: receiving an adaptive command (110); and identifying the adaptive command, and determining, according to the adaptive command, to execute the first communications protocol or the second communications protocol for an operation (120). According to the foregoing method, the storage device can perform an adaptive operation between different communications protocols.
