Abstract:
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.
