Transmitter optical sub-assembly receptacle with thicker split sleeve
View Patent ↗A transmitter optical sub-assembly receptacle includes a thicker split sleeve positioned within a cylindrical shell structure and partly within a base structure such that a fiber ferrule, which is positioned within the base structure, is partly within the thicker split sleeve. The split sleeve has a thickness larger than 0.187 millimeter.
1. A transmitter optical sub-assembly receptacle comprising:
a base structure including a longitudinal hole;
a fiber ferrule positioned within said longitudinal hole of said base structure;
a cylindrical shell structure partly positioned within said longitudinal hole of said base structure; and
a split sleeve positioned within said cylindrical shell structure and partly within said longitudinal hole of said base structure such that a part of said fiber ferrule is positioned within said split sleeve, said split sleeve having a thickness larger than 0.187 millimeter,
wherein said longitudinal hole of said base structure includes a first circular hole section at a first end of said base structure and a second circular hole section at a second end of said base structure, said first end being engaged with said cylindrical shell structure, the diameter of said first circular hole section being larger than the diameter of said second circular hole section, and wherein said longitudinal hole of said base structure includes an intermediate hole section connecting said first circular hole section and said second circular hole section, the diameter of said intermediate hole section being smaller than said diameter of said first circular hole section and larger than said diameter of said second circular hole section, said diameter of said intermediate hole section being uniformed.
2. The receptacle of claim 1 wherein said thickness of said split sleeve is uniform.
3. The receptacle of claim 1 wherein said thickness of said split sleeve is approximately 0.377 millimeter.
4. The receptacle of claim 1 wherein said cylindrical shell structure includes a cylindrical hole in which said split sleeve is positioned, the diameter of said cylindrical hole being larger than 2.4 millimeter.
5. The receptacle of claim 4 wherein said diameter of said cylindrical shell structure is approximately 2.92 millimeter.
6. The receptacle of claim 1 wherein the thickness of said cylindrical shell structure along its length is uniform.
7. The receptacle of claim 1 wherein said cylindrical shell structure includes a cylindrical hole in which said split sleeve is positioned, said diameter of said intermediate hole section being substantially equal to the diameter of said cylindrical hole.
8. The receptacle of claim 1 wherein the dimensions of said receptacle resulting from said base structure, said fiber ferrule, said cylindrical shell structure and said split sleeve conform to the FOCIS 10 standard for LC receptacles.
9. The receptacle of claim 1 wherein said base structure and said cylindrical shell are made of metal and said split sleeve is made of ceramic material.
10. A transmitter optical sub-assembly receptacle comprising:
a base structure including a longitudinal hole, said longitudinal hole having a first circular hole section at a first end of said base structure and a second circular hole section at a second end of said base structure, the diameter of said first circular hole section being larger than the diameter of said second circular hole section;
a fiber ferrule positioned within said longitudinal hole of said base structure;
a cylindrical shell structure partly positioned within said first circular hole section of said longitudinal hole of said base structure; and
a split sleeve positioned within said cylindrical shell and partly within said longitudinal hole of said base structure such that a part of said fiber ferrule is positioned within said split sleeve, said split sleeve having a uniform thickness larger than 0.187 millimeter,
wherein said longitudinal hole of said base structure includes an intermediate hole section connecting said first circular hole section and said second circular hole section, the diameter of said intermediate hole section being smaller than said diameter of said first circular hole section and larger than said diameter of said second circular hole section, said diameter of said intermediate hole section being uniformed.
11. The receptacle of claim 10 wherein said uniform thickness of said split sleeve is approximately 0.377 millimeter.
12. The receptacle of claim 10 wherein said cylindrical shell structure includes a cylindrical hole in which said split sleeve is positioned, the diameter of said cylindrical hole being larger than 2.4 millimeter.
13. The receptacle of claim 12 wherein said diameter of said cylindrical shell structure is approximately 2.92 millimeter.
14. The receptacle of claim 10 wherein the thickness of said cylindrical shell structure along its length is uniform.
15. The receptacle of claim 10 wherein said cylindrical shell structure includes a cylindrical hole in which said split sleeve is positioned, said diameter of said intermediate hole section being substantially equal to the diameter of said cylindrical hole.
16. The receptacle of claim 10 wherein the dimensions of said receptacle resulting from said base structure, said fiber ferrule, said cylindrical shell structure and said split sleeve conform to the FOCIS 10 standard for LC receptacles.
17. The receptacle of claim 10 wherein said base structure and said cylindrical shell are made of metal and said split sleeve is made of ceramic material.
