Abstract

A cable connector system can include a board connector that attaches to a die package, a cable connector that attaches to the board connector, and a 1RU panel I/O connector attached to the cable connector.

First claim

What is claimed is:

1. A front panel of a rack-mountable equipment comprising:
a 1RU area of the front panel defined by an approximately 1.75 inches by approximately 19 inches area;
a plurality of cable connectors each including eight shielded differential twin axial cables, each of the eight shielded differential twin axial cables including respective center cable conductors each having a gauge of 32 AWG to 36 AWG; and
at least thirty-two panel I/O connectors positioned within the 1RU area of the front panel such that one-thousand and twenty-four 56-GHz NRZ capable differential signal pairs are provided in the 1RU area, wherein
the plurality of cable connectors are each individually terminated with a corresponding one of the at least thirty-two panel I/O connectors,
each of the thirty-two panel I/O connectors includes first, second, third, and fourth rows of electrical conductors, and
each of the first, second, third, and fourth rows of electrical conductors includes eight differential signal pairs and a plurality of ground conductors arranged in a S-S-G configuration.

2. The front panel of claim 1 , further comprising a plurality of board connectors physically connected to a first die substrate surface of a die substrate, wherein
respective ones of the plurality of cable connectors are connected to respective ones of the plurality of board connectors.

3. The front panel of claim 2 , wherein
the plurality of board connectors includes twelve two-row board connectors positioned on the first die substrate surface of the die substrate; and
at least two of the plurality of cable connectors are connected to a respective one of the twelve two-row board connectors such that at least one hundred and ninety-two of the one-thousand and twenty-four 56-GHz NRZ capable differential signal pairs are provided on the first die substrate surface.

4. The front panel of claim 3 , wherein
the plurality of board connectors includes twelve two-row board connectors positioned on a second die substrate surface of the die substrate; and
at least two of the plurality of cable connectors are connected to a respective one of the twelve two-row board connectors such that at least one hundred and ninety-two of the one thousand and twenty-four 56-GHz NRZ capable differential signal pairs are provided on the second die substrate surface.

5. The front panel of claim 2 , wherein
the plurality of board connectors includes twelve four-row board connectors positioned on the first die substrate surface of the die substrate; and
at least four of the plurality of cable connectors are connected to a respective one of the twelve four-row board connectors such that at least three hundred and eighty-four of the one-thousand and twenty-four 56-GHz NRZ capable differential signal pairs are provided on the first die substrate surface.

6. The front panel of claim 5 , wherein
the plurality of board connectors includes twelve four-row board connectors positioned on a second die substrate surface of the die substrate; and
at least four of the plurality of cable connectors are connected to a respective one of the twelve four-row board connectors such that at least three hundred and eighty-four of the one thousand and twenty-four 56-GHz NRZ capable differential signal pairs are provided on the second die substrate surface.

7. The front panel of claim 1 , wherein the front panel is capable of transporting at least 50 terabytes of data with a frequency domain crosstalk of −40 dB or better.

8. The front panel of claim 1 , wherein a first pitch between the first and the second rows of electrical conductors is different from a second pitch between the second and the third rows of electrical conductors.

9. The front panel of claim 1 , further comprising a magnetic absorbing material that is either electrically conductive or electrically non-conductive and that is located on and/or in at least one of the plurality of cable connectors.

10. The front panel of claim 1 , further comprising a plurality of board connectors attached to a die substrate, attached to an extension card attached to the die substrate, or attached to a host substrate, wherein
the plurality of cable connectors is connected to a respective one of the plurality of board connectors.

11. The front panel of claim 1 , wherein differential far end crosstalk is between −30 dB and −100 dB through frequencies up to 40 GHz when transporting 56-GHz NRZ signals.

12. The front panel of claim 1 , wherein differential near end crosstalk is between −40 dB and −100 dB through frequencies up to 40 GHz when transporting 56-GHz NRZ signals.

13. The front panel of claim 2 , wherein dimensions of the die package substrate are N by N, where N is greater than or equal to 70 mm and N is less than or equal to 200 mm.

14. The front panel of claim 2 , wherein dimensions of the die package substrate are 85 mm by 85 mm, 90 mm by 90 mm, 95 mm by 95 mm, 100 mm by 100 mm, 105 mm by 105 mm, or 110 mm by 110 mm.

15. The front panel of claim 2 , further comprising a magnetic absorbing material that is either electrically conductive or electrically non-conductive and that is located on and/or in at least one of the plurality of board connectors.

16. The front panel of claim 2 , wherein
at least one of the plurality of board connectors includes a housing; and
a height of the housing is approximately 1.5 mm to approximately 7 mm.

17. The front panel of claim 2 , wherein
at least one of the plurality of board connectors includes a housing; and
a height of the housing is approximately 4 mm to approximately 7 mm.

18. The front panel of claim 2 , wherein
the plurality of cable connectors includes first and second cable connectors;
the first and the second cable connectors are vertically stacked on a corresponding one of the plurality of board connectors such that the first and the second cable connectors are immediately adjacent; and
the first cable connector does not fully overlap the second cable connector.

19. The front panel of claim 2 , wherein
the plurality of cable connectors includes first, second, and third cable connectors;
the first, the second, and the third cable connectors are vertically stacked on a corresponding one of the plurality of board connectors such that the first and the second cable connectors are immediately adjacent and such that the second and the third cable connectors are immediately adjacent; and
an overlap between the first cable connector and the second cable connector is larger than an overlap between the second cable connector and the third cable connector.

20. The front panel of claim 3 , wherein a mated stack height of one of the twelve two-row board connectors of the plurality of board connectors and the at least two of the plurality of cable connectors is greater than zero but less than approximately 5 mm.
