Abstract

The present disclosure generally relates to devices, which may be used in communication or optoelectronic modules for example, suitable for arrayed positioning of a plurality of fiber optical components. In one form, an optoelectronic module includes a printed circuit board (PCB) and at least one optical component array device including an array of laterally or radially spaced receptacles configured to receive an optical component. One or more of the receptacles includes a fused fiber optical component positioned therein. A recursive fiber may extend between an output of a first fused fiber optical component and an input of a second fused fiber optical component, and an optical fiber routing member may be coupled to the PCB and include a plurality of guides extending away from the PCB and defining a pathway for routing optical fibers relative to the PCB.

First claim

What is claimed is:

1. An optoelectronic module, comprising:
a printed circuit board (“PCB”) that extends between opposite ends and includes one or more electrical or optical connectors at one or both ends thereof; and
an optical component array device that includes an elongate body configured to position a plurality of fused fiber optical components relative to the PCB in an array of laterally or radially spaced receptacles along a longitudinal axis of the elongate body,
wherein at least one of the receptacles includes an elongate opening sized to receive at least one of the plurality of fused fiber optical components, and the at least one of the receptables opens through a surface of the elongate body along the longitudinal axis.

2. The optoelectronic module of claim 1 , further comprising an optical fiber routing member coupled to the PCB, wherein the routing member includes a plurality of guides that extend away from the PCB and that define a pathway to route optical fibers relative to the PCB.

3. The optoelectronic module of claim 1 , wherein the elongate body of the optical component array device includes an elongated cylindrical body that extends between a first end and an opposite second end of the elongated cylindrical body; and wherein the receptacles are radially spaced around an outer circumference of the elongated cylindrical body.

4. The optoelectronic module of claim 3 , wherein each of the receptacles extends between and opens at the first end and the second end of the elongated cylindrical body.

5. The optoelectronic module of claim 4 , wherein the elongate opening extends between the first end and the second end of the elongated cylindrical body.

6. The optoelectronic module of claim 3 , wherein the optical component array device further includes a cylindrical cover positioned around the elongated cylindrical body.

7. The optoelectronic module of claim 1 , wherein the elongate body extends between a first end and an opposite second end of the elongate body; and wherein the receptacles are laterally spaced between opposite sides of the elongate body.

8. The optoelectronic module of claim 7 , wherein each of the receptacles includes a first portion positioned adjacent the first end of the elongate body and a second portion spaced from the first portion and positioned adjacent to the second end of the elongate body.

9. The optoelectronic module of claim 8 , wherein the elongate body includes a recessed portion positioned between the first and second portions of the receptacles.

10. The optoelectronic module of claim 7 , wherein the optical component array device further includes a cover positioned over the receptacles and the fused fiber optical components, and a tray in which the elongate body is positioned.

11. The optoelectronic module of claim 1 ,
wherein the elongate body includes an elongated cylindrical body that extends between a first end and an opposite second end; and
wherein the array of laterally or radially spaced receptacles includes a plurality of receptacles radially spaced around an outer circumference of the elongated cylindrical body,
wherein one or more of the receptacles is defined by an elongate slot that extends between and opens at the first and second ends of the elongated cylindrical body; and
wherein one of the receptacles is configured to receive a first one of the fused fiber optical components.

12. The optoelectronic module of claim 11 , wherein each of the plurality of receptacles is configured to receive a corresponding one of the fused fiber optical components.

13. The optoelectronic module of claim 12 , further comprising a cover that encloses the elongated cylindrical body.

14. The optoelectronic module of claim 12 , further comprising a recursive fiber that extends between an output of the first fused fiber optical component and an input of a second one of the fused fiber optical components.

15. The optoelectronic module of claim 1 ,
wherein the elongate body extends along a longitudinal axis between a first end and an opposite second end of the elongate body and laterally between a first side and an oppositely positioned second side of the elongate body;
wherein the array of laterally or radially spaced receptacles includes a plurality of receptacles laterally spaced from one another and positioned between the first and second sides of the elongate body,
wherein one of the receptacles is configured to receive a fused fiber optical component; and
wherein the elongate body includes a cover member positioned over the elongate body and configured to cooperate with the elongate body to receive therebetween a first of the fused fiber optical components.

16. The optoelectronic module of claim 15 , wherein the plurality of receptacles are defined by a plurality of grooves formed in the elongate body; and wherein the plurality of grooves extend in-line with the longitudinal axis.

17. The optoelectronic module of claim 16 , wherein the grooves include a first portion spaced from a second portion by a recessed surface of the elongate body.

18. The optoelectronic module of claim 15 , further comprising a recursive fiber that extends between an output of the first fused fiber optical component and an input of a second one of the fused fiber optical components.

19. An optoelectronic module, comprising:
a printed circuit board (“PCB”) that extends between opposite ends and includes one or more electrical or optical connectors at one or both ends thereof; and
an optical component array device that includes an elongate body configured to position a plurality of fused fiber optical components relative to the PCB in an array of laterally or radially spaced receptacles,

wherein the elongate body extends between a first end and an opposite second end of the elongate body; and wherein the receptacles are laterally spaced between opposite sides of the elongate body,
wherein each of the receptacles includes a first portion positioned adjacent the first end of the elongate body and a second portion spaced from the first portion and positioned adjacent to the second end of the elongate body, and
wherein the first and second portions of the receptacles include a modified V-shaped configuration having a first surface, a second surface that extends transversely to the first surface, and a third surface that extends between and transversely to the first surface and the second surface.

20. An optoelectronic module, comprising:
a printed circuit board (“PCB”) that extends between opposite ends and includes one or more electrical or optical connectors at one or both ends thereof; and
an optical component array device that includes an elongate body configured to position a plurality of fused fiber optical components relative to the PCB in an array of laterally or radially spaced receptacles,
