Abstract
Official abstract text for this publication.
A transmitter optical sub-assembly includes a body and a receptacle assembled to a front side of the body, the receptacle including a nose body, a split sleeve enclosed by the nose body, a first body disposed behind the split sleeve, and a fiber stub either glued or shrink fit or pressed fit on to the first body, a rear end of the split sleeve being slip fitted on to the fiber stub; wherein the nose body is made from deep drawing or cold forging process and is attached on to a front surface of the body.
First claim
Opening claim text (preview).
What is claimed is: 1. A transmitter optical sub-assembly (TOSA) comprising: a TOSA body; and a receptacle assembled to a front side of the TOSA body, the receptacle including a nose body, a split sleeve enclosed by the nose body, a first body disposed behind the split sleeve and fully received within the nose body, and a fiber stub either glued or shrink fit or pressed fit on to the first body, a rear end of the split sleeve being slip fitted on to the fiber stub; wherein said nose body is unitarily of a cylindrical structure with at least two different diameters on two different areas along a front-to-back direction; wherein the nose body includes at least four sections along said front-to-back direction, a front section rearwardly extending from a front end of the nose body and having a first diameter and a first axial dimension, a flange section located at a rear end of the nose body and extending radially with a largest diameter, a rear section forwardly extending from the flange section and having a second diameter smaller than the that of the flange section while larger than the first diameter, and a second axial dimension larger than that of the flange section while smaller than the first axial dimension, and an oblique transition section located between the front section and the rear section. 2. The transmitter optical sub-assembly as claimed in claim 1 , wherein said oblique transition section has both oblique outer surface and inner surface opposite to each other. 3. The transmitter optical sub-assembly as claimed in claim 1 , wherein a front end of the first sleeve is essentially intimately located around the oblique transition section. 4. The transmitter optical-assembly as claimed in claim 1 , wherein a nose body is made by either a deep drawing process with a constant thickness therealong, or a cold forging process with different thicknesses therealong.
