Abstract
The optical module includes a main housing, a light-emitting component supported by a second attachment section, a light-receiving component and a filter support member supported by a third attachment section, and first and second optical filters supported by the filter support member. The filter support member has a first surface and a second surface. The first optical filter is mounted on the first surface of the filter support member. The second optical filter is mounted on the second surface of the filter support member.
Claims20
An optical module, comprising:
- a main housing having a first attachment section that can affix an optical fiber, a second attachment section located in opposition to said first attachment section, and a third attachment section provided at a first angle to a straight line which connects said first and second attachment sections;
- a light-emitting component supported by said second attachment section;
- a light-receiving component supported by said third attachment section;
- a filter support member being a cap that optically isolates the light-receiving component from the main housing, the filter support member supported by said third attachment section;
- and first and second optical filters supported by said filter support member, said filter support member having a first surface which has a second angle different from said first angle to said straight line and a second surface which is substantially perpendicular to said light-receiving component, said first optical filter being mounted on said first surface of said filter support member, said second optical filter being mounted on said second surface of said filter support member, wherein the second optical filter mounted on the second surface and the cap eliminate all stray or scattered light within the main housing, that is not incident on the second optical filter, from reaching the light-receiving component.
An optical module, comprising:
- a housing;
- an optical light-receiving component;
- and
- a coupling and mounting means attached to said housing and coupled to said optical light-receiving component, so as to couple said optical light-receiving component to the housing and for mounting one or more optical filters in proper alignment, wherein the one or more optical filters are mounted to the coupling and mounting means so as to be aligned with the optical light-receiving component and filter an optical communication signal sent to or from an optical fiber while eliminating all stray or scattered light not incident on the one or more optical filters within said housing from reaching said optical light-receiving component.
An optical module comprising;
- a housing;
- a first light communication member coupled to the housing at a first location;
- a second light communication member coupled to the housing at a second location;
- a filter support member attached to the housing;
- a first filter attached to the filter support member at a first angle;
- a second filter attached to the filter support member at a second angle;
- and
- a third light communication member coupled to the filter support member, wherein the filter support member and the second filter blocks undesired stray and scattered light from the first light communication member within the housing that is not incident on the one or more optical filters from reaching the third light communication member.
