Connector assemblies for optoelectronic modules
View Patent ↗In one embodiment, an optoelectronic assembly may include at least one transmitter or at least one receiver, a sleeve, a housing, a fiber stub, and a receptacle. The sleeve may define a sleeve opening sized and shaped to receive an optically transmissive portion of an optical fiber. The housing may define a housing cavity at least partially enclosing the transmitter or the receiver. The housing may include a lens port defining a lens port opening. The fiber stub may be positioned at least partially in the sleeve opening and the lens port opening. The receptacle may define a receptacle opening. The lens port, the sleeve and the fiber stub may be positioned at least partially in the receptacle opening.
1. A connector assembly for an optoelectronic assembly comprising:
a fiber stub including an optically transmissive medium and a channel extending at least partially around a circumference of the fiber stub;
a sleeve defining a sleeve opening sized and shaped to receive the fiber stub and a corresponding optically transmissive portion of an optical fiber;
a housing defining a housing cavity at least partially enclosing at least one transmitter or at least one receiver, the housing comprising a lens port defining a lens port opening sized and shaped to receive a portion of the fiber stub;
a second channel defined between the fiber stub and the lens port, the second channel including a flared configuration to permit the fiber stub to be adjusted in the lens port; and
a receptacle defining a receptacle opening sized and shaped to receive the lens port, the sleeve and the fiber stub;
wherein:
the fiber stub is positioned at least partially in the lens port opening and the sleeve opening; and
the sleeve and the lens port are positioned at least partially in the receptacle opening.
2. The connector assembly of claim 1 , wherein the receptacle is configured to mate with an optical fiber connector of the optical fiber.
3. The connector assembly of claim 1 , the housing and the receptacle comprising a plastic material.
4. The connector assembly of claim 3 , the receptacle further comprising a material that attenuates EMI or a metal filler that prevents light from passing therethrough.
5. The connector assembly of claim 3 , wherein the housing is at least partially transparent between the fiber stub and the transmitter or the receiver.
6. The connector assembly of claim 1 , the housing further comprising at least one optical component optically coupled with the transmitter or the receiver.
7. The connector assembly of claim 1 , the sleeve comprising a slot extending at least partially between a first end and a second end of the sleeve.
8. The connector assembly of claim 1 , further comprising openings extending into an interior of the receptacle, transverse to a longitudinal axis of the receptacle.
9. An optoelectronic assembly comprising:
at least one transmitter or at least one receiver;
a sleeve defining a sleeve opening sized and shaped to receive an optically transmissive portion of an optical fiber;
a housing defining a housing cavity at least partially enclosing the transmitter or the receiver, the housing comprising a lens port defining a lens port opening;
a fiber stub positioned at least partially in the sleeve opening and the lens port opening, the fiber stub defining a channel extending at least partially around a circumference of the fiber stub;
a second channel defined between the fiber stub and the lens port, the second channel including a flared configuration to permit the fiber stub to be adjusted in the lens port; and
a receptacle defining a receptacle opening, wherein the lens port, the sleeve and the fiber stub are positioned at least partially in the receptacle opening.
10. The optoelectronic assembly of claim 9 , wherein the receptacle is configured to mate with an optical fiber connector of the optical fiber.
11. The optoelectronic assembly of claim 9 , the housing and the receptacle comprising a plastic material.
12. The optoelectronic assembly of claim 11 , the receptacle further comprising a material that attenuates EMI or a metal filler that prevents light from passing therethrough.
13. The optoelectronic assembly of claim 11 , wherein the housing is at least partially transparent between the fiber stub and the transmitter or the receiver.
14. The optoelectronic assembly of claim 9 , the housing further comprising at least one optical component optically coupled with the transmitter or the receiver.
15. The optoelectronic assembly of claim 9 , the sleeve comprising a slot extending at least partially between a first end and a second end of the sleeve.
16. The optoelectronic assembly of claim 9 , further comprising openings extending into an interior of the receptacle, transverse to a longitudinal axis of the receptacle.
17. The optoelectronic assembly of claim 9 , further comprising openings extending into an interior of the lens port, transverse to a longitudinal axis of the lens port.
18. The optoelectronic assembly of claim 9 , wherein the fiber stub, the sleeve, the receptacle, and the lens port are arranged concentrically with respect to one another.
19. The optoelectronic assembly of claim 9 , further comprising a second channel defined between the lens port and the receptacle, the second channel extending at least partially around a circumference of the lens port.
