Abstract

Embodiments include a high bandwidth optical connection system suitable for interconnecting servers, for example within a rack of a datacenter. An edge mount optical connector assembly includes an edge-mount housing providing topside socket contacts proximate to a first end of the housing and a port at a second end to receive an optical plug connector. A socket latch cantilevered from an anchor point on the housing includes a latching face to contact a keeper face disposed on the housing and a spring load application surface between the anchor point and the latching face to apply a spring force against the electrical contacts for retention of a removable optical transceiver module. An optical plug connector includes a front housing joined to a rear housing with a plug lens spring loaded within the housing and with alignment features comprising two flat alignment surfaces orthogonally oriented relative to each other.

First claim

What is claimed is:

1. An edge mount optical connector assembly, comprising:
an edge-mount housing including top side socket contacts proximate to a first end of the housing and a port at a second end, opposite the first, to receive an optical plug connector;
an outer shield wrapping around at least a top surface of edge-mount housing between the first and second housing ends;
a socket latch cantilevered from an anchor point coupled to the housing, the socket latch including:
a latching face to contact a keeper face associated with the housing; and
a spring load application surface between the anchor point and the latching face to apply a spring force in against the electrical contacts; and

an optical transceiver module to covert between optical signals passing through the port and electrical signals passing through the socket contacts, wherein the optical transceiver module includes bottom side electrical contacts to make physical contact with the top side socket contacts; and
a heat sink comprising a bottom-side to make contact with a top side of the optical transceiver module, and heat dissipation features, wherein the socket latch further comprises a pair of the spring load application surfaces straddling the heat dissipation features, with each of the spring load application surfaces to apply the spring force.

2. The edge mount optical connector assembly of claim 1 , wherein the optical transceiver module further comprises at least two alignment posts proximate to the first end of the housing to align with alignment features in the optical plug connector when engaged in the port, and wherein at least one of the alignment posts further comprises at least a pair of flats surfaces oriented orthogonally to each other.

3. The edge mount optical connector assembly of claim 1 ,
wherein the socket latch is to contact the heat sink with the spring load application surface and apply the spring force to both the heat sink and the optical transceiver module.

4. The edge mount optical connector assembly of claim 1 , further comprising a printed circuit board soldered to first ends of the socket contacts.

5. An edge mount optical connector assembly, comprising:
an edge-mount housing including top side socket contacts proximate to a first end of the housing and a port at a second end, opposite the first, to receive an optical plug connector;
an outer shield wrapping around at least a top surface of edge-mount housing between the first and second housing ends;
a socket latch cantilevered from an anchor point coupled to the housing,
the socket latch including:
a latching face to contact a keeper face of the housing; and
a spring load application surface between the anchor point and the latching face to apply a spring force against the electrical contacts; and

an optical plug connector assembly, wherein the optical plug connector assembly further comprises
a front housing joined to a rear housing;
a plug lens disposed within the front or rear housing, wherein the plug lens comprises an array of lenses disposed in a front face between two alignment features, at least one of the alignment features comprising two flat alignment surfaces orthogonally oriented relative to each other;
a plurality of optical fibers extending from a raw cable assembly and through the rear housing and affixed to the plug lens; and
a coil spring, wherein the plurality of optical fibers pass through turns of the spring and wherein the coil spring is compressed between the plug lens and the rear housing.

6. The edge mount optical connector assembly of claim 5 , further comprising:
an optical transceiver module to covert between optical signals passing through the port and electrical signals passing through the socket contacts, wherein the optical transceiver module includes bottom side electrical contacts to make physical contact with the top side socket contacts.

7. The edge mount optical connector assembly of claim 6 , wherein the optical transceiver module further comprises at least two alignment posts proximate to the first end of the housing to align with alignment features in the optical plug connector when engaged in the port, and wherein at least one of the alignment posts further comprises at least a pair of flats surfaces oriented orthogonally to each other.

8. The edge mount optical connector assembly of claim 6 , further comprising:
a heat sink comprising a bottom-side to make contact with a top side of the optical transceiver module, and heat dissipation features, wherein the socket latch is to contact the heat sink with the spring load application surface and apply the spring force to both the heat sink and the optical transceiver module.

9. The edge mount optical connector assembly of claim 6 , wherein the socket latch further comprises a pair of the spring load application surfaces straddling the heat dissipation features, with each of the spring load application surfaces to apply the spring force.

10. The edge mount optical connector assembly of claim 6 , further comprising a printed circuit board soldered to first ends of the socket contacts.
