High frequency test fixture
View Patent ↗An apparatus for testing optical components. The apparatus includes a component cavity. The component cavity includes a package portion generally including fit tolerances but otherwise including a similar size and shape of an optical component to be tested. The component cavity further includes an electrical interface portion that can hold electrical interface leads of the optical component. The apparatus further includes an optical fiber interface optically connected to the cavity. The optical fiber interface mates with an optical fiber. The optical fiber is connected optically to the optical component being tested.

an electrical interface portion configured to receive electrical interface leads of the optical component; and
a latch mechanism configured to secure the optical component; and
an optical fiber interface coupled to the cavity, the optical fiber interface configured to mate with an optical fiber and configured to optically couple the optical fiber to the optical component being tested; and
one or more biasing springs and support members configured to help position the optical component to be tested into an appropriate location.
2. The apparatus of claim 1 , wherein the electrical interface portion is configured to receive a flex circuit.
3. The apparatus of claim 1 , further comprising pogo pins disposed at or near the electrical interface portion, the pogo pins being configured to contact electrical connections to the optical component.
4. The apparatus of claim 1 , wherein the optical fiber interface comprises an LC receptacle.
5. The apparatus of claim 1 , wherein the optical fiber interface comprises an SC receptacle.
6. The apparatus of claim 1 , wherein the package portion is adapted to receive a TO can package.
7. The apparatus of claim 1 , the apparatus comprising a base and a lid, and wherein at least a portion of the component cavity is disposed in the lid.
8. The apparatus of claim 1 , the apparatus comprising a base and a lid, and wherein at least a portion of the component cavity is disposed in the base.
9. The apparatus of claim 1 , the apparatus comprising a base and a lid, and wherein the base and the lid are coupled together with a hinge and selectively engageable with each other by way of the latch mechanism.
10. A method of testing optical components, the method comprising:
placing the optical component into a package portion of a component cavity, the package portion generally including fit tolerances but otherwise including a similar size and shape of the optical component;
placing leads coupled to the package in an electrical interface portion of the component cavity;
securing the optical component using a latch mechanism; and
connecting a fiber-optic cable including a connector to a receptacle mating with the connector such that the fiber-optic cable is optically coupled to the optical component.
11. The method as recited in claim 10 , wherein the optical component comprises a TO can package.
12. The method as recited in claim 10 , further comprising using the optical component to generate an optical signal.
13. The method as recited in claim 10 , further comprising receiving an optical signal at the optical component.
14. An apparatus for testing optical components, the apparatus comprising:
a component cavity, the component cavity comprising:
a package portion generally including fit tolerances but otherwise including a similar size and shape of an optical component to be tested; and
an electrical interface portion configured to receive electrical interface leads of the optical component;
an optical fiber interface coupled to the cavity, the optical fiber interface configured to mate with an optical fiber and configured to optically couple the optical fiber to the optical component being tested; and
one or more biasing springs and support members configured to help position the optical component to be tested into an appropriate location.
15. The apparatus as recited in claim 14 , wherein the optical fiber interface comprises one of: an LC connector; or, an SC connector.
16. The apparatus as recited in claim 14 , wherein the apparatus comprises a base and a lid that collectively define a clamshell configuration, at least a portion of the component cavity being defined by the lid.
17. The apparatus as recited in claim 14 , further comprising a latch mechanism configured to secure the optical component, the latch mechanism comprising a pair of latches.
18. The apparatus as recited in claim 14 , wherein the optical component comprises one of: an optical receiver; and, an optical transmitter.
