A connector cable includes a plurality of contacts placed in a row and a plurality of cables connected to the plurality of contacts. The plurality of cables includes at least three pairs of high-speed differential signal lines for transmitting high-speed differential signals, at least one non-high-speed differential signal line for transmitting a non-high-speed differential signal, and a plurality of ground terminals. The plurality of ground terminals is allocated to contacts on both ends among the plurality of contacts and a contact between two pairs of high-speed differential signal lines or between one pair of high-speed differential signal lines and one non-high-speed differential signal line to limit the number of consecutive pairs of high-speed differential signal lines to two.

To help maintain and improve signal integrity, a connector housing can include one or more of the following: asymmetric keying features, asymmetric alignment features, and alternating stitched contacts. First and second contact rows and third and fourth contact rows can each have a first row pitch, and the second and the third contact rows can have a second, greater row pitch. First and second keying structures can be positioned non-symmetrically about both longitudinal and median centerlines of the connector housing. If first, second, third, and fourth contacts all lie on a common centerline of the connector housing, the first and the third contacts can be inserted in a first direction, and the second and the fourth contacts can be inserted in a second, opposite direction. First and second contact securing structures can engage the connector housing at different heights of the connector housing.

An auxiliary device for functional expansion and signal acquisition of a testing system is provided with a pogo pin attaching device including at least one spiral spring loop, at least one fastening member, and at least one cable.
