OPTICAL FIBER TRANSMISSION DEVICE, HOUSING FOR OPTICAL FIBER TRANSMISSION DEVICE, AND ELECTROMAGNETIC INTERFERENCE SHIELDING CASING

摘要

PROBLEM TO BE SOLVED: To simultaneously shield a fiber optic transceiver(FOT) to an optical fiber coupled to the FOT by a connector housing, and to appropriately impart tolerance.;SOLUTION: In an FOT connector housing 10, which combines an FOT 20 with an optical fiber 20 and maintains them in order to keep a desired space between an FOT interface 17 and the optical fiber 22, EMI shielding for an FOT consists of an FOT metal casing 30 which is in contact with the wall of the casing to maintain the interface side of the FOT, the wall of the casing 30 has a thickness designed, so that the desired space between the FOT interface 17, and the optical fiber 22 is realized and maintained, and the metal casing 30 has spring members 30d which resists an FOT cavity 16, so that the FOT interface 17 is maintained, at a desired space from the optical fiber 22 under the strain of springs.;COPYRIGHT: (C)2002,JPO
