Abstract
Abstract A fiber optic module includes a first housing insert molded with an electromagnetic interference (EMI) shield, an optoelectronic subassembly mounted in the first housing, and a second housing mounted to the first housing to enclose the optoelectronic subassembly. The EMI shield includes a conductive mesh and conductive contact fingers. The first housing includes a non-conductive housing floor, non-conductive housing sidewalls, and a non-conductive nose defining at least one connector receptacle, wherein the housing floor and the housing sidewalls are injection molded through the mesh of the EMI shield to be integral with the nose and so that the fingers at least partially surround the nose.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
53 words
A fiber optic module, comprising an electromagnetic interference (EMI) shield, comprising: a conductive mesh defining (1) small openings that shield EMI and (2) at least one large opening that allows a fiber optic connector to pass through the conductive mesh; and conductive contact fingers; a first housing insert molded with the EMI shield.
Claim 2
Dependent Claim
53 words
A fiber optic module, comprising an electromagnetic interference (EMI) shield, comprising: a conductive mesh defining (1) small openings that shield EMI and (2) at least one large opening that allows a fiber optic connector to pass through the conductive mesh; and conductive contact fingers; a first housing insert molded with the EMI shield.
Claim 3
Dependent Claim
31 words
The module of claim 1 , wherein the EMI shield further comprises conductive shield sidewalls extending perpendicularly from a perimeter of the mesh, the contact fingers extending from the shield sidewalls.
Claim 4
Dependent Claim
