Coupling unit for coupling an optical transmitting and/or receiving module to an optical fiber connector
First Claim
1. A coupling unit for coupling an optical transmitting and/or receiving module to an optical fiber connector, the coupling unit comprising:
- a connecting region for connecting to the transmitting and/or receiving module, a receiving region for receiving the optical fiber connector, anda glass component, via which light is coupled directly between the optical fiber inserted into the receiving region and the transmitting and/or receiving module,wherein the coupling unit is formed as a plastic part apart from the glass component,wherein the glass component is introduced into a bore in the plastic part,wherein the receiving region is formed for receiving a ceramic ferrule which centrally contains an optical fiber to be coupled on, andwherein the glass component comprises a first cylindrical portion on a side facing the connecting region and a second cylindrical portion on a side facing the receiving region, the first cylindrical portion being smaller in diameter than the second cylindrical portion.

Abstract
A coupling unit for coupling an optical transmitting and/or receiving module to an optical fiber connector. The coupling unit has a connecting region, which can be connected to a transmitting and/or receiving module, a receiving region, which receives an optical fiber connector, and a glass component, via which light is coupled directly between an optical fiber inserted into the receiving region and a coupled-on transmitting and/or receiving module. In this case, the coupling unit is formed as a plastic part apart from the glass component. The glass component is introduced into a bore in the plastic part.

12. A coupling unit for coupling an optical transmitting/receiving module to an optical fiber connector such that optical signals can be passed between the optical transmitting/receiving module and the optical fiber connector, the coupling unit comprising:
-
an integrally-molded plastic part including; a receiving sleeve for receiving the optical fiber connector such that a glass fiber of the optical fiber connector is aligned in a first bore defined by the receiving sleeve, and such that an end face of the glass fiber is located at an end of the first bore, a connecting structure for coupling the transmitting/receiving module such that a transmitting/receiving element of the transmitting/receiving module is located inside a connecting region defined by the connecting structure, and a central structure located between the receiving structure and the connecting structure, the central structure defining a second bore defining a passage between the first bore and the connecting region; and a glass component fixedly mounted with an adhesive cement in the second bore, at least a portion of the glass component having an outside diameter substantially the same as an inside diameter of the second bore, the glass component including a first end face located proximate the end of the first bore, and a second end face protruding into a clearance between the second bore and the connecting region, and the glass component being located such that, when the transmitting/receiving module is mounted in the connecting structure, said optical signals can be passed between the transmitting/receiving element and the second end face of the glass component.
