Abstract

An optoelectronic apparatus comprising a casing (110) inside which an electronic unit and an optical unit electrically interconnected are disposed; the optical unit comprises an element (100) on which at least one component is housed, which can be of an optical type, of optical connection, of an electro-optical type (270, 275, 300), said element (100) comprising a plurality of separate areas (190, 195), so that each area houses components substantially of a single type.

Claims

1. A method of assembling an optoelectronic apparatus comprising a casing (110) having closure means (340), an optical unit (100) having a plurality of areas (190, 195, 290) and an electronic unit (350), characterized in that it comprises the following steps:

disposing at least an optical connection component on said optical unit (100) in one of said areas and optionally, a component belonging to one of the following groups;

of an optical type (50,

     250), of an electro-optical type (270, 275,

     300) in others of said areas, each of said plurality of areas having components substantially of a single type mounted thereon;

inserting said optical unit (100) into said casing (110), one portion of said optical unit (100) being directly accessible from the outside and comprises at lease one area (190) of said plurality of areas, said optical connection components being disposed on said at least one area (190);

electrically connection said electronic unit (350) to said optical unit (100);

securing said electronic unit (350) to said optical unit (100);

closing said casing (110) by said closure means (340) so as to removably hold said units in said casing.

2. An optoelectronic apparatus comprising a casing (340, 110) within which an electronic united (350) and an optical unit electrically interconnected are disposed, said optical unit comprising a mounting element (100) on which components of an optical type (50, 250) and optical connection are mounted characterized in that said element (100) comprises a plurality of separate area (190, 195, 290), each of said plurality of areas having components substantially of a single type mounted thereon and said element (100) comprises a first face and an oppositely facing a second face, the area (190) for optical-connection components being located on said first face, the area (290) for components of the optical type (50, 250) being located on said second face, the area for the optical connection components having substantially the same size as the area for the optical type components and being aligned with the area for the optical type components in the direction from said first surface to said second surface.

3. An apparatus according to claim 2, wherein there is an area (195) for components of the electro-optical type (270, 275, 300)which is adjacent to said area (290) for components of the optical type (50, 250) and said area (190) for optical-connection components.

4. An apparatus according to claim 3, wherein said at least one component of the electro-optical type passes through said element (100).

5. An apparatus according to claim 4, wherein said area (195) for optical-connection components is directly accessible from the exterior, once said electronic unit (350) has been removed.

6. An apparatus according to claim 5, wherein said area (190) for optical-connection components comprises a receiver (120) for collecting surplus optical-fiber lengths and an area (140, 160, 170) for housing splices interconnecting optical fiber lengths.

7. An apparatus according to claim 6, wherein said receiver (120)comprises means (122, 124) for retaining said surplus fiber lengths in said receiver.

8. An apparatus according to claim 6, wherein said area (140, 160, 170) for housing splices is disposed close to the casing (110, 340) edges.

9. An optoelectronic apparatus comprising a casing (340, 110) within which an electronic unit (350) and an optical unit electrically interconnected are disposed, said optical unit comprising a substantially monolithic element (100) housing at least one component, said component belonging to one of the following groups:

of an optical type (50,

     250), of optical connection, of an electro-optical type (270, 275,

     300), characterized in that said element (100) comprises a plurality of separate areas (190, 195,

     290), each of said plurality of areas housing components substantially of a single type and comprises a first face in opposition to a second face, the area (190) for optical-connection components being placed on said first face and the area (290) for components of the optical type (50,

     250) being placed on said second face, each area substantially having the same size as, and being in opposition to the other area and wherein the area (195) for components of the electro-optical type (270, 275,

     300) is adjacent to said area (290) for components of the optical type (50,

     250) and said area (190) for optical-connection components and wherein said at least one component of the electro-optical type passes through said element (100).
