Integrated optical splitter system
View Patent ↗A system and method directed to an integrated fiber optic splitter assembly having at least two fused splitters disposed in a common substrate. An integrated optical splitter assembly includes a plurality of input fibers, a plurality of output fibers, and a plurality of splitters disposed on a single substrate to either split or couple optical signals between the input and output optical fibers.
1. An integrated optical splitter assembly, comprising:
a single substrate;
a plurality of first optical fibers;
a plurality of second optical fibers;
a plurality of optical splitters forming an intact assembly disposed on the single substrate, the optical splitters configured to perform at least one of splitting or coupling optical signals between the first optical fibers and the second optical fibers; and
a single external housing configured to substantially enclose the assembly.
2. The integrated optical splitter assembly of claim 1 , wherein the single external housing is attached to the substrate using an adhesive.
3. The integrated optical splitter assembly of claim 1 , wherein the single external housing is a rectangular metal tube.
4. The integrated optical splitter assembly of claim 1 , wherein the single external housing is supported by the substrate.
5. The integrated optical splitter assembly of claim 1 , wherein the single substrate includes a plurality of grooves, each groove adapted to receive a coupling region of one of the plurality of optical splitters.
6. The integrated optical splitter assembly of claim 5 , wherein each of the plurality of grooves at least partially encompass one of the plurality of first optical fibers or second optical fibers.
7. The integrated optical splitter assembly of claim 1 , further comprising a top cover positioned to overlay the plurality of optical splitters.
8. The integrated optical splitter assembly of claim 7 , wherein the housing encircles the single substrate, the top cover, and the plurality of optical splitters.
9. The integrated optical splitter assembly of claim 1 , further comprising an adhesive bonding the plurality of first optical fibers to the single substrate.
10. The integrated optical splitter assembly of claim 1 , further comprising an adhesive bonding the plurality of second optical fibers to the single substrate.
11. The integrated optical splitter assembly of claim 1 , wherein the single substrate has a thermal expansion coefficient similar to that of the plurality of first optical fibers and the plurality of second optical fibers.
12. The integrated optical splitter assembly of claim 1 , wherein the single substrate is substantially planar.
13. The integrated optical splitter assembly of claim 1 , wherein the single substrate is at least partially cylindrical.
14. An integrated optical splitter assembly, comprising:
a plurality of optical fibers;
a single substrate;
a plurality of optical splitters forming an intact assembly and located on the single substrate, the plurality of optical splitters configured to split optical signals among the plurality of optical fibers; and
a single external housing configured to substantially enclose the intact assembly, wherein the single external housing is supported by the substrate;
wherein the single substrate includes a plurality of grooves, each groove adapted to receive a coupling region of one of the plurality of optical splitters and at least partially encompass one of the plurality of optical fibers.
15. The integrated optical splitter assembly of claim 14 , wherein the single substrate is substantially planar.
16. The integrated optical splitter assembly of claim 14 , wherein the single substrate is at least partially cylindrical.
17. The integrated optical splitter assembly of claim 14 , further comprising an adhesive bonding the plurality of optical fibers to the single substrate.
18. The integrated optical splitter assembly of claim 14 , further comprising a top cover positioned to overlay the plurality of optical splitters.
