7. The cassette of claim 1 , further comprising a bond bar coupled to the housing, the bond bar being configured to be electrically connected to a grounded component to define a ground path between the grounded component and housing.
8. The cassette of claim 7 , wherein the bond bar is electrically connected to the shield elements.
9. The cassette of claim 1 , wherein the circuit board is positioned behind each of the contact sets generally between the contact sets and a rear of the housing.
10. The cassette of claim 1 , wherein the circuit board has a first side and a second side, the contacts extend from the first side, the contact subassembly has at least one electrical connector mounted to the second side of the circuit board that is electrically connected to the contacts of one or more of the contact sets.
11. The cassette of claim 1 , wherein the contact subassembly includes a plurality of contact supports extending from the circuit board in close proximity to respective contact sets, the contact supports supporting the contacts of corresponding contact sets, the contact supports being received in different plug cavities when the contact subassembly is loaded into the housing, the shield elements at least partially surrounding the contact supports.
12. A cassette comprising:
a housing having exterior walls and interior walls being integrally formed with one another, the interior walls and the exterior walls cooperating to define a plurality of plug cavities arranged in a stacked configuration in a first row and a second row, wherein the plug cavities are separated from adjacent plug cavities by shield elements being at least one of defined by, provided on, or provided in the interior walls separating the plug cavities, the shield elements providing electromagnetic shielding between adjacent plug cavities; and
a contact subassembly having a circuit board and a plurality of contacts arranged in contact sets coupled to the circuit board, the contact sets being configured to mate with different plugs, the contact subassembly being loaded into the rear chamber such that the contact sets are received in different plug cavities, wherein the contact sets are separated from adjacent contact sets by the shield elements.
13. The cassette of claim 12 , wherein the housing is diecast, the diecast interior walls between the plug cavities defining the shield elements.
14. The cassette of claim 12 , wherein the shield elements are separate from the housing and coupled to the interior walls of the housing.
15. The cassette of claim 12 , wherein the shield elements completely enclose the plug cavities.
16. The cassette of claim 12 , wherein the shield elements electrically isolate the contact sets from one another.
17. A cassette comprising:
a housing having a front and a rear, the housing being configured to be received within an opening of a grounded panel, the housing having shielded interior walls defining a plurality of plug cavities being open at the front for receiving plugs therein, the plug cavities being separated from adjacent plug cavities by the interior walls, the plug cavities being electromagnetically shielded from adjacent plug cavities by shield elements being at least one of defined by, provided on, or provided in the interior walls;
a bond bar coupled to the housing, the bond bar being configured to be electrically connected to the grounded panel to define a ground path between the panel and the shield elements; and
a contact subassembly received in the housing, the contact subassembly having a circuit board and a plurality of contacts arranged in contact sets received in different plug cavities, wherein the contact sets are separated from adjacent contact sets by the grounded shield elements.
