Abstract

An opto-mechanical coupler and corresponding method are provided. The coupler may include a first end and a second end configured to receive optical fibers and a top surface and bottomed surface defining a through hole extending between the top and bottom surfaces. The coupler may include a reflective surface that redirects the optical signals between a first direction and a second direction substantially perpendicular to the first direction. The coupler may position one or more optical fibers along a second direction such that an optical signal from the plurality of optoelectronic transceivers is directed into one or more optical fibers or an optical signal from the one or more optical fibers is directed into a plurality of the optoelectronic transceivers, with the coupler accommodating different diameters of optical fiber including POF, SMF, and/or MMF fiber.

First claim

The invention claimed is:

1. An opto-mechanical coupler comprising:
a body defining:
a first end configured to receive one or more optical fibers having a first diameter;
a second end opposite the first end, wherein the second end is configured to receive one or more optical fibers having a second diameter;
a bottom surface supporting a plurality of optical lenses, wherein the optical lenses are configured to allow passage of optical signals traveling in a first direction for transmission to or from a plurality of optoelectronic transceivers disposed proximate the bottom surface, and
a top surface opposite the bottom surface,
wherein the body defines at least one through-hole extending between the top surface and the bottom surface, wherein the through-hole is configured to receive a pin therethrough; and

a reflective surface configured to redirect the optical signals between the first direction and a second direction substantially perpendicular to the first direction,
wherein, in an installed state, the coupler is configured to receive the one or more optical fibers via only a selected one of the first end or the second end so as to position the one or more optical fibers along the second direction via the selected one of the first end or the second end and such that an optical signal from the plurality of optoelectronic transceivers is directed into the one or more optical fibers or an optical signal received from the one or more optical fibers is directed into the plurality of the optoelectronic transceivers.

2. The opto-mechanical coupler according to claim 1 , wherein the first end defines grooves configured to locate each optical fiber at a height relative to a first optical path in the second direction.

3. The opto-mechanical coupler according to claim 1 , wherein the first diameter and the second diameter are not equal.

4. The opto-mechanical coupler according to claim 1 , wherein the first end defines grooves configured to locate each optical fiber at a height relative to a first optical path in the second direction, and wherein the second end defines grooves configured to locate each optical fiber at a second height relative to a second optical path in the second direction, wherein the first height and the second height are not equal.

5. The opto-mechanical coupler according to claim 1 , wherein the first end further comprises an aperture configured to receive an optical fiber, wherein the aperture defines a distal diameter and a proximal diameter, wherein the proximal diameter is smaller than the distal diameter.

6. The opto-mechanical coupler according to claim 1 , wherein the one or more optical fibers are plastic optical fibers or single mode optical fibers.

7. The opto-mechanical coupler according to claim 1 , wherein the coupler is configured to receive optical signals having a nominal wavelength of 1310 nm.

8. A method of manufacturing an opto-mechanical coupler comprising:
forming a body defining a first end, a second end opposite the first end, a bottom surface, a top surface, and a reflective surface, wherein the first end is configured to receive one or more optical fibers having a first diameter and the second end is configured to receive one or more optical fibers having a second diameter;
supporting a plurality of optical lenses via the bottom surface of the body, wherein the optical lenses are configured to allow passage of optical signals traveling in a first direction for transmission to or from a plurality of optoelectronic transceivers disposed proximate the bottom surface; and
defining at least one through-hole extending between the top surface and the bottom surface, wherein the through-hole is configured to receive a pin therethrough;
wherein, in an installed state, the coupler is configured to receive the one or more optical fibers via only a selected one of the first end or the second end so as to position the one or more optical fibers along the second direction via the selected one of the first end or the second end and such that an optical signal from the plurality of optoelectronic transceivers is directed into the one or more optical fibers or an optical signal received from the one or more optical fibers is directed into the plurality of the optoelectronic transceivers.

9. The method according to claim 8 , wherein the first end defines grooves configured to locate each optical fiber at a height relative to a first optical path in the second direction, and wherein the second end defines grooves configured to locate each optical fiber at a second height relative to a second optical path in the second direction, wherein the first height and the second height are not equal.

10. The method according to claim 8 , wherein the one or more optical fibers are plastic optical fibers or single mode optical fibers.

11. The method according to claim 8 , wherein the coupler is configured to receive optical signals having a nominal wavelength of 1310 nm.

12. The method according to claim 8 , wherein the first diameter and the second diameter are not equal.
