Connector for box optical subassembly
View Patent ↗Discloses is a transceiver module having a box optical subassembly, a printed circuit board, and a connector extending from the box optical subassembly to the printed circuit board. The box optical subassembly includes a laser diode, a laser driver, and at least one pin receiving a driver signal for said laser driver. Optionally, the box optical subassembly includes a thermal electric cooler to cool one or more components within the box optical subassembly. The connector mounts to the at least one pin and is receivable by a pin header mounted to the printed circuit board to accommodate for variations in the orientation of the optical subassembly relative to the printed circuit board during optical alignment of the optical subassembly.
1. A transceiver module comprising:
a base portion;

a printed circuit board disposed between the base portion and the top portion, wherein said printed circuit board further comprises at least one pin header, said at least one pin header comprises a plurality of pins arranged in two rows; and
a rigid connector having physical dimensions that extend at least from said at least one pin to said printed circuit board, the base portion, and the top portion, wherein said rigid connector comprises a plurality of a plurality of pad contacts, each of said plurality of pad contacts being selectively connectable with at least one pin of said plurality of pins.
2. A transceiver module as recited in claim 1 , wherein said plurality of pins arranged in two rows selectively receive said rigid connector to accommodate variations in the alignment of the optical subassembly and the printed circuit board.
3. A transceiver module as recited in claim 1 , wherein said rigid connector comprises a first surface and a second surface, each of said first surface and said second surface comprises at least one of said plurality of pad contacts.
4. A transceiver module as recited in claim 1 , wherein said optical subassembly further comprises at least one thermal electric cooler.
5. A transceiver module as recited in claim 4 , wherein said at least one pin receives at least one control signal for said at least one thermal electric cooler.
6. A transceiver module as recited in claim 1 , wherein said rigid connector further comprises at least one through-hole contact, said at least one pin being selectively received by said at least one through-hole contact.
7. A transceiver module comprising:
a top portion mountable to a base portion, said base portion comprising a cavity defined by at least one wall and a base;
an optical subassembly mountable within said cavity, said optical subassembly comprising a laser diode, a laser driver, and a plurality of optical subassembly pins, at least one of said plurality of pins selectively receiving a driver signal for said laser driver;
a printed circuit board mountable within said cavity, said printed circuit board comprising a plurality of pin header pins; and
a connector extending from said plurality of optical subassembly pins to said printed circuit board, said connector mountable within said cavity between a portion of said optical subassembly and said at least one wall,
wherein said connector comprises a plurality of pad contacts, said pad contacts being selectively connectable with said plurality of pin header pins.
8. A transceiver module as recited in claim 7 , wherein said connector comprises a first portion and a second portion, said second portion extending from said base to said top portion.
9. A transceiver module as recited in claim 8 , wherein said second portion comprises a plurality of through-hole contacts, said plurality of optical subassembly pins being selectively received within said plurality of through-hole contacts.
10. A transceiver module as recited in claim 7 , wherein said plurality of pin header pins are arranged in two rows.
11. A transceiver module as recited in claim 10 , wherein said two rows of pin header pins are spaced apart to receive at least a portion of the connector.
12. A transceiver module as recited in claim 7 , wherein each pad contact of said plurality of pad contacts engages with a pin of said plurality of pin header pins, a position of each engaged pad contact relative to its corresponding pin header pin being based upon a position of said optical subassembly relative to said printed circuit board.
13. A transceiver module as recited in claim 7 , wherein said plurality of pad contacts selectively mount to said plurality of pin header pins and said plurality of through-hole contacts selectively receive said plurality of optical subassembly pins to align said optical subassembly to said printed circuit board in at least one of an x-direction, a y-direction and a z-direction.
