Abstract
Abstract An active device mount assembly 1 comprises an interface mount 4 having front socket 9. Further included is an active device 5. The assembly 1 may also include a focusing element 6. The device 5 has an emission axis aimed along the axis of the optical focusing element. The assembly 4 further comprises a coupler element 7 aligned with the focusing element 6 and inserting into a precise depth into the socket 9 of the mount 4. Further the interface mount 4 provides means for attaching a fiber optic connector 3 where the fiber optic connector 3 has an alignment ferrule 66 and an optical fiber 10 extending therethrough. The alignment ferrule 66 abuts the coupler element 7 with the optical fiber 10 aligned to the center axis of the coupler element 7. The interface mount for attaching the fiber optic connector 36 further comprises a base 28 with an alignment sleeve 29 and at least two resilient catch pieces 30 extending from the base 28. The alignment sleeve 29 has longitudinal axis and axial bore encompassing the alignment ferrule 66 of the fiber optic connector 36. The resilient catch pieces 30 are of cantilever form extending parallel to and on opposing sides of the longitudinal axis of the alignment sleeve 29 and terminating in protrusions 32 and lip structures 33.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
153 words
An active device mount assembly for disconnectable connection with a fiber optic connector comprising, an active device base and an active device mounted thereto and interface mount for attaching a fiber optic connector having an alignment ferrule and optical fiber extending therethrough, said interface mount comprising: a base with a front socket extending therefrom and having a longitudinal axis and an axial bore; and at least two resilient catch pieces of cantilever form extending from the base parallel to and on opposing sides of the longitudinal axis of the front socket and terminating in protrusions and lip structures, the protrusions being constructed to contact respective beveled leading edges of the fiber optic connector and the catch pieces to rise along the leading edges, and causing each lip to travel over ridges of the fiber optic connector behind the leading edges and to seat within slots of the fiber optic connector behind the ridges.
Claim 2
Dependent Claim
153 words
An active device mount assembly for disconnectable connection with a fiber optic connector comprising, an active device base and an active device mounted thereto and interface mount for attaching a fiber optic connector having an alignment ferrule and optical fiber extending therethrough, said interface mount comprising: a base with a front socket extending therefrom and having a longitudinal axis and an axial bore; and at least two resilient catch pieces of cantilever form extending from the base parallel to and on opposing sides of the longitudinal axis of the front socket and terminating in protrusions and lip structures, the protrusions being constructed to contact respective beveled leading edges of the fiber optic connector and the catch pieces to rise along the leading edges, and causing each lip to travel over ridges of the fiber optic connector behind the leading edges and to seat within slots of the fiber optic connector behind the ridges.
Claim 3
Dependent Claim
86 words
The active device mount assembly of claim 1 further including an optical focusing element encompassed within the axial bore of said socket with longitudinal axis of the focusing element aligned with the longitudinal axis of the said axial bore; and an optical coupler element aligned with the focusing element and inserted to a precise depth into the socket of the assembly mount, and further abutting the alignment ferrule of said fiber optic connector with the optical fiber aligned to the center axis of said coupler element.
Claim 4
Dependent Claim
