Abstract

A communications device may include a connector block. The connector block may include a port. The port may be sized and configured to couple an optical fiber plug. The communications device may include an optical subassembly that may be connected to the connector block. The connector block may include a mount. The mount may be sized and configured to align the connector block and the optical subassembly. The mount may be configured as an EMI shield.

Claims (22)

1. An apparatus comprising:

a transmitter optical subassembly comprising:

a front portion including an end; and

a nosepiece configured to convey optical signals, the nosepiece extending away from the end of the front portion of the transmitter optical subassembly;

a receiver optical subassembly comprising:

a front portion including an end; and

a nosepiece configured to convey optical signals, the nosepiece extending away from the end of the front portion of the receiver optical subassembly;

a first monolithic body including a port that is sized and configured to couple an optical fiber plug;

a first EMI shield connected to the first monolithic body and to the transmitter optical subassembly, the first EMI shield including a recessed portion that includes an end and an opening formed in the end, the end of the recessed portion of the first EMI shield abutting the end of the front portion of the transmitter optical subassembly, the nosepiece of the transmitter optical subassembly extending through the opening formed in the end of the recessed portion of the first EMI shield;

a second monolithic body including a port that is sized and configured to couple an optical fiber plug; and

a second EMI shield connected to the second monolithic body and to the receiver optical subassembly, the second EMI shield including a recessed portion that includes an end and an opening formed in the end, the end of the recessed portion of the second EMI shield abutting the end of the front portion of the receiver optical subassembly, the nosepiece of the receiver optical subassembly extending through the opening formed in the end of the recessed portion of the second EMI shield, wherein the first EMI shield includes one or more resiliently deformable or resiliently deflectable members; and wherein the second EMI shield includes one or more resiliently deformable or resiliently deflectable members that contact the one or more resiliently deformable or resiliently deflectable members of the first EMI shield.

2. The apparatus as in claim 1 , further comprising a housing that houses at least a portion of the transmitter optical subassembly, at least a portion of the receiver optical subassembly, at least a portion of the first monolithic body, at least a portion of the first EMI shield, at least a portion of the second monolithic body, and at least a portion of the second EMI shield.

3. The apparatus as in claim 2 , wherein the first EMI shield includes one or more resiliently deformable members that contact the housing; and wherein the second EMI shield includes one or more resiliently deformable members that contact the housing.

4. The apparatus as in claim 2 , wherein the first EMI shield includes one or more resiliently deflectable members that contact the housing; and wherein the second EMI shield includes one or more resiliently deflectable members that contact the housing.

5. An apparatus comprising:

a transmitter optical subassembly including a nosepiece configured to convey optical signals;

a receiver optical subassembly including a nosepiece configured to convey optical signals;

a first body including a port that is sized and configured to couple an optical fiber plug;

a first EMI shield connected to the first body, the first EMI shield including an opening and one or more resilient members, the nosepiece of the transmitter optical subassembly extending through the opening of the first EMI shield;

a second body including a port that is sized and configured to couple an optical fiber plug; and

a second EMI shield connected to the second body, the second EMI shield including an opening and one or more resilient members, the nosepiece of the receiver optical subassembly extending through the opening of the second EMI shield, at least one resilient member of the second EMI shield contacting at least one resilient member of the first EMI shield.

6. The apparatus as in claim 5 , wherein the first EMI shield is a mount to which the transmitter optical subassembly is connected; and wherein the second EMI shield is a mount to which the receiver optical subassembly is connected.
