Abstract
A parallel optical transceiver module is provided that uses a folded flex circuit arrangement that reduces the footprint of the transceiver module while also providing the module with improved heat dissipation characteristics. In addition, the manner in which components are mounted on the flex circuit facilitates assembly of the module, reducing the overall cost of the module while improving manufacturing yield.
Claims10
A parallel optical transceiver module comprising:
- a folded flex circuit having at least upper and lower surfaces and having at least first, second, third, fourth, and fifth flex circuit portions, the flex circuit having a flexible substrate of dielectrically insulating material and a plurality of electrical conductors disposed in or on the substrate, and wherein the first and fifth flex circuit portions extend generally in respective planes that are generally co-planar to one another and generally parallel to a plane in which the third flex circuit portion extends such that the upper surface of the flex circuit in the first and fifth flex circuit portions are generally co-planar and generally parallel to the upper surface of the flex circuit in the third flex circuit portion;
- at least a first optical/electrical device mounted on the first flex circuit portion on the upper surface of the flex circuit;
- at least a second optical/electrical device mounted on the fifth flex circuit portion on the upper surface of the flex circuit;
- and
- at least one electrical connector mounted on the third flex circuit portion on the upper surface of the flex circuit, wherein the upper surface of the flex circuit in the first flex circuit portion is generally parallel to the upper surface of the flex circuit in the third flex circuit portion.
