7. The apparatus as in claim 1 , further comprising an epoxy that connects the mount to the optical subassembly.
8. The apparatus as in claim 7 , wherein at least a portion of the epoxy is sandwiched between the end of the recessed portion and the end of the front portion of the optical subassembly.
9. The apparatus as in claim 7 , wherein at least a portion of the epoxy is sandwiched between the side of the recessed portion and the side of the front portion of the optical subassembly.
10. The apparatus as in claim 7 , wherein at least a portion of the epoxy is sandwiched between the end of the recessed portion and the end of the front portion of the optical subassembly and wherein at least a portion of the epoxy is sandwiched between the side of the recessed portion and the side of the front portion of the optical subassembly.
11. The apparatus as in claim 1 , wherein the optical subassembly is a transmitter optical subassembly.
12. The apparatus as in claim 1 , wherein the optical subassembly is a receiver optical subassembly.
13. An apparatus comprising:
an optical subassembly comprising:
a front portion including an end and a side; and
a nosepiece configured to convey optical signals, the nosepiece extending away from the front portion; and
a monolithic body comprising:
a port that is sized and configured to couple an optical fiber plug;
one or more notches configured for engaging a housing configured to cover the monolithic body and the optical subassembly; and
a sheet metal mount connected to the optical subassembly, the mount including a recessed portion, the recessed portion including a side, an end and an opening formed in the end, the end of the recessed portion abutting the end of the front portion of the optical subassembly, the side of the recessed portion abutting the side of the front portion of the optical subassembly, the nosepiece of the optical subassembly extending through the opening formed in the end of the recessed portion, the mount also including one or more flanges configured for engaging the monolithic body, the one or more flanges being positioned substantially perpendicular to the recessed portion of the mount.
14. The apparatus as in claim 13 , wherein the side of the front portion of the optical assembly has a shape; and wherein the side of the recessed portion of the mount has a shape that is generally complementary to the shape of the side of the front portion of the optical assembly.
15. A method for assembling an apparatus that includes an optical subassembly and a connector block, the optical subassembly including a front portion and a nosepiece extending away from the front portion, the front portion including an end and a side, the nosepiece being configured to convey optical signals, the connector block including a monolithic body and a sheet metal mount, the monolithic body including a port that is sized and configured to be couple an optical fiber plug, the mount including a recessed portion, the recessed portion including a side, an end and an opening formed in the end of the recessed portion, the method comprising:
using an adhesive to secure the optical subassembly to the connector block; and
directly connecting the sheet metal mount to the monolithic body by having the mount touch the monolithic body, the mount including one or more flanges, the mount being at least partially directly connected to the monolithic body by the one or more flanges, the one or more flanges being positioned substantially perpendicular to the recessed portion of the mount.
16. The method as in claim 15 , wherein the using an adhesive to secure the optical subassembly to the connector block comprises:
sandwiching at least a portion of the adhesive between the end of the recessed portion and the end of the front portion of the optical subassembly.
