Plug module system
A plug module is provided that includes a first mating end and a second mating end. The first mating end is configured to mate with a predefined port, such as a QSFP port. The second mating end can support two or more micro receptacles that allow the plug module to provide an octopus-like cable assembly without requiring the predetermination of a particular length of cable.
1. A plug module, comprising:
a body with a first mating end and a second mating end, the first end configured to be inserted into a predefined port;
a paddle card positioned in the first end and including a plurality of contact pads, the paddle card configured to receive at least two transmit channels and two receive channels;
a first micro receptacle and a second micro receptacle supported in the second mating end, wherein the first and second micro receptacle are each configured to include one of the two transmit channels and one of the two receive channels; and
a micro board that supports the first and second micro receptacles, the first micro receptacle being mounted on the micro board and the second micro receptacle being mounted on the micro board.
2. The module of claim 1 , wherein at least one cable connects the micro board to the paddle card.
3. The module of claim 1 , wherein the micro receptacles are positioned on two sides of the micro board and the micro board is offset upward compared to the paddle card.
4. The module of claim 1 , wherein each micro receptacle has at least 8 pins arranged on a 0.5 mm pitch.
5. The module of claim 1 , wherein each micro receptacle includes an individual latch, each latch configured, in operation, to releasably engage a mating micro plug module.
6. A plug module system, comprising:
a plug module as defined in claim 5 ; and
a cable assembly mated to the plug module, the cable assembly including a micro plug connector with terminals at a 0.5 mm pitch, wherein the micro receptacle and the micro plug connector are configured to support 12.5 GHz signaling over a transmit channel and a receive channel with less than 35 dB far end crosstalk.
7. The module system of claim 6 , wherein the cable assembly has an SFP connector mounted on the other end.
8. The module system of claim 6 , wherein a plurality of cable assemblies are mounted to the plug module, wherein one of the plurality of cable assemblies has a first length and another of the plurality of cables assembles has a second length, the first length being different than the second length.
9. The module of claim 1 , wherein at least one cable electrically connects the paddle card to at least one of the first micro receptacle and the second micro receptacle.
10. The module of claim 9 , wherein the at least one cable connects the paddle card to the at least one of the first micro receptacle and the second micro receptacle.
11. The module of claim 1 , wherein flex circuitry electrically connects the paddle card to at least one of the first micro receptacle and the second micro receptacle.
12. The module of claim 1 , wherein the micro board comprises a planar circuit board.
13. The module of claim 1 , wherein the module further comprises circuitry that includes at least one of a retimer and an amplifier.
14. A plug module, comprising:
a body with a first mating end and a second mating end, the first end configured to be inserted into a predefined port;
a paddle card positioned in the first mating end and including a plurality of contact pads, the paddle card configured to receive at least two transmit channels and two receive channels;
a first micro receptacle and a second micro receptacle supported in the second mating end, wherein the first and second micro receptacle are each configured to include one of the two transmit channels and one of the two receive channels; and
a micro board that supports the first and second micro receptacles, the first micro receptacle being mounted on a first side of the micro board and the second micro receptacle being mounted on a second side of the micro board, the first side of the micro board being opposite the second side of the micro board.
15. The plug module of claim 14 , wherein at least one cable electrically connects the paddle card to at least one of the first micro receptacle and the second micro receptacle.
16. The plug module of claim 15 , wherein the at least one cable connects the paddle card to the at least one of the first micro receptacle and the second micro receptacle.
17. The plug module of claim 14 , wherein flex circuitry electrically connects the paddle card to at least one of the first micro receptacle and the second micro receptacle.
18. The plug module of claim 14 , wherein the micro board comprises a planar circuit board.
19. The plug module of claim 14 , wherein the plug module fluffier comprises circuitry that includes at least one of a retimer and an amplifier.
20. The plug module of claim 14 , wherein each micro receptacle has at least 8 pins arranged on a 0.5 mm pitch.
