Testing pluggable module

1. A testing pluggable module comprising:

a pluggable body extending between a front end and a mating end defining a mating interface with a communication connector of a receptacle assembly, the mating end being receivable in a module cavity of the receptacle assembly to mate with the communication connector, the pluggable body having an exterior forward of the mating end;

an internal circuit board held in the pluggable body, the internal circuit board having a testing circuit operating at least one testing function; and

a user interface on the exterior of the pluggable body, the user interface having an input configured to operably control the at least one testing function of the testing circuit.

2. The testing pluggable module of claim 1 , wherein the user interface is accessible on the pluggable body when the pluggable body is loaded in the module cavity of the receptacle assembly and mated with the communication connector.

3. The testing pluggable module of claim 1 , wherein the input is a physical input configured to be adjusted by a user.

4. The testing pluggable module of claim 1 , wherein the input is movable relative to the pluggable body between at least two positions.

5. The testing pluggable module of claim 1 , wherein the input is a switch having multiple positions to control the at least one testing function.

6. The testing pluggable module of claim 1 , wherein the user interface is a touch screen having at least one of multiple inputs.

7. The testing pluggable module of claim 1 , wherein the input is an electronic input.

8. The testing pluggable module of claim 1 , wherein the pluggable body includes a top, a bottom and sides therebetween defining the exterior, the user interface being provided on either the top or the bottom.

9. The testing pluggable module of claim 1 , wherein the user interface is provided at the front end.

10. The testing pluggable module of claim 1 , further comprising a display on the exterior of the pluggable body, the display receiving an output from the testing circuit and displaying information indicative of the output.

11. The testing pluggable module of claim 1 , further comprising a heat generator held in the pluggable body and operably coupled to the test circuit, the input controlling operation of the heat generator.

12. The testing pluggable module of claim 11 , wherein the input controls a temperature of the heat generator.

13. The testing pluggable module of claim 1 , further comprising a signaling unit configured to at least one of transmit data signals to or receive data signals from the communication connector, the signaling unit being operably coupled to the testing circuit, the input controlling operating parameters of the signaling unit for diagnostic testing.

14. The testing pluggable module of claim 13 , wherein the input is changeable to alter the operating parameters of the signaling unit.

15. A testing pluggable module comprising:

a pluggable body extending between a front end and a mating end defining a mating interface with a communication connector of a receptacle assembly, the mating end being receivable in a module cavity of the receptacle assembly to mate with the communication connector, the pluggable body having an exterior forward of the mating end;

an internal circuit board held in the pluggable body, the internal circuit board having a testing circuit operating at least one testing function, the testing circuit having an output based on at least one testing function;

a user interface on the exterior of the pluggable body, the user interface having an input configured to operably control the at least one testing function of the testing circuit; and

a display on the exterior of the pluggable body, the display receiving the output from the testing circuit and displaying information indicative of the output.

16. A testing pluggable module comprising:

a pluggable body extending between a front end and a mating end defining a mating interface with a communication connector of a receptacle assembly, the mating end being receivable in a module cavity of the receptacle assembly to mate with the communication connector, the pluggable body having an exterior forward of the mating end;

an internal circuit board held in the pluggable body, the internal circuit board having a testing circuit operating at least one testing function, the testing circuit having an output based on the at least one testing function; and

a display on the exterior of the pluggable body, the display receiving the output from the testing circuit and displaying information indicative of the output.

17. The testing pluggable module of claim 16 , wherein the display is a graphical display showing icons indicative of the output.

18. The testing pluggable module of claim 16 , wherein the display is visible from the exterior of the receptacle assembly.

19. The testing pluggable module of claim 16 , wherein the display is provided at the front end.
