Patent number: 9011025Abstract: A modified TO-can assembly is provided that has greater versatility with respect to spatial constraints than known TO-can assemblies and that is suitable for use in a wider range of applications than known TO-can assemblies. The modified TO-can assembly has a receptacle that has been modified to receive an optical fiber through its side instead of through its end. Within the TO-can assembly, the optical path is folded in order to couple the light between the optoelectronic component of the TOSA or ROSA and the end of the optical fiber. The combination of these features provides the modified TO-can assembly with a compact profile that makes it more versatile with respect to spatial constraints and therefore suitable for use in a wider range of applications.Type: GrantFiled: December 19, 2011Date of Patent: April 21, 2015Assignee: Avago Technologies General IP (Singapore) Pte.
