Pin cadence for high-speed connectors

A connector comprising:

• a plurality of pins having a pinout including at least one functional designation cadence including a first ground pin, a first signal pin, a second signal pin, and a second ground pin, wherein:
• the first signal pin is positioned between the first ground pin and the second signal pin;
• the first signal pin is separated from the first ground pin by a pitch;
• the first signal pin is separated from the second signal pin by two times the pitch;
• the second signal pin is positioned between the first signal pin and the second ground pin;
• and
• the second signal pin is separated from the second ground pin by the pitch;
• a printed circuit board (PCB) including a plurality of contacts electrically coupled to the plurality of pins and having a PCB contact pinout including a PCB contact functional designation cadence corresponding to the at least one functional designation cadence, wherein the PCB contact functional designation cadence includes a first ground contact, a first signal contact, a second signal contact, and a second ground contact arranged in sequence according to the functional designation cadence;
• and
• a metallic electromagnetic radiation shield that at least partially surrounds the plurality of pins.

An active cable device comprising:

• an optical cable having opposing first and second ends and including an optical fiber extending from the first end to the second end;
• and
• an optoelectronic connector coupled to the first end of the optical cable, wherein the optoelectronic connector comprises:
• a connector housing;
• a printed circuit board (PCB) positioned within the connector housing;
• an optical component coupled to the PCB, wherein the optical component is optically coupled to a first end of the optical fiber so as to emit light into or receive light from the optical fiber;
• a plurality of pins having a pinout including at least one functional designation cadence including a first ground pin, a first signal pin, a second signal pin, and a second ground pin,
• wherein:
• the first ground pin, the first signal pin, the second signal pin, and the second ground pin are arranged in sequence;
• the PCB includes a plurality of contacts arranged in sequence according to the functional designation cadence;
• the plurality of contacts of the PCB include a first ground contact coupled to the first ground pin, a first signal contact coupled to the first signal pin, a second signal contact coupled to the second signal pin, and a second ground contact coupled to the second ground pin;
• and
• the PCB includes a plurality of traces, including a first trace that electrically couples the first ground contact to the optical component and a second trace that electrically couples the second ground contact to the optical component.
