Abstract
Abstract A sealed enclosing system for coupling an emitting or receiving optoelectronic device with an optical fibre. A metal cap has an optical fibre passing therethrough in a sealed manner. A bellows tube is mounted on a base and thus provides an elastic element for connecting the fibre to an optoelectronic diode mounted on the tube. The seal is completed by a welding of the cap to the base and by passing electric supply connections through the passage ways formed by glass beads.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
95 words
A sealed system for coupling an optoelectronic device and an optical fiber, comprising: a first enclosure consisting of a metal cap having, at its top, a sealed passageway for an optical fibre, said cap being welded onto a base; a second enclosure, located in said first enclosure, consisting of a length of bellows tube closed by a metallic plate at one end and welded to said base at the other end, said base being common to both of said enclosures; a platform adapted to support said optoelectronic device and being integral with said metallic plate.
Claim 2
Dependent Claim
95 words
A sealed system for coupling an optoelectronic device and an optical fiber, comprising: a first enclosure consisting of a metal cap having, at its top, a sealed passageway for an optical fibre, said cap being welded onto a base; a second enclosure, located in said first enclosure, consisting of a length of bellows tube closed by a metallic plate at one end and welded to said base at the other end, said base being common to both of said enclosures; a platform adapted to support said optoelectronic device and being integral with said metallic plate.
Claim 3
Dependent Claim
25 words
A system as claimed in claim 1, wherein said common base is bored to allow said second enclosure to be filled by a polymerizable resin.
Claim 4
Dependent Claim
22 words
A system as claimed in claim 1, wherein said second enclosure comprises an internal heat dissipator positioned in contact with said base.
Claim 5
Dependent Claim
30 words
A system as claimed in claim 1, wherein said common base comprises sealed passageways for conductors adapted to supply the optoelectronic device with electrical polarization and to transmit optoelectronic signals.
Claim 6
Dependent Claim
31 words
A system as claimed in claim 1, wherein said platform is supplied with an electrically insulating and thermally conductive disc destined to be inserted between said platform and said optoelectronic device.
