An optical fiber adapter structure, comprises a metal flange, a tubular housing, an insulating ring, an optical fiber stub, and a shielding annulus. The optical fiber stub is embedded into the metal flange; the shielding annulus is fixed at a bottom of the metal flange by means of a conductive adhesive; the shielding annulus covers an end of the optical fiber stub and is provided with a reserved hole only for laser signals to pass through; the tubular housing is sleeved to the bottom of the metal flange; and the tubular housing is insulated from the metal flange by means of the insulating ring. The conductive adhesive adheres the shielding annulus made of conductive material to a tail end of the metal flange and maintains complete electrical contact therebetween, such that the electromagnetic wave radiation between the interior of optical device and the exterior of metal flange is reduced.

An in-application upgrade method is used for optical module firmware not breaking a service. A storage area for internal programs of an optical module is divided into two areas which are respectively used for storing upgrade and application programs, and is divided into an area for backing up an interrupt vector table of a Boot program. An upper computer is in communication with the optical module. The interrupt vector table is switched, and the jump between the Boot program and the application program is achieved. The method includes extracting the contents of firmware, entering a download mode and updating the firmware. The original firmware is erased, and new firmware is written. An application mode is entered, the upper computer sending an exit command from the download mode. The upgrade program exits and a new application program is executed. The optical module operates normally without interruption.
