Round-flat twisted pair cable assembly

A round-flat twisted pair cable assembly comprising:

• a plurality of twisted pairs rolled together;
• each of said twisted pairs defining a local phase offset angle with regard to a neighboring twisted pair, and a global pair centerline angle with regard to a global horizontal axis, said twisted pairs being characterized in that:
• θGi=θGi−2−2αi;
• wherein θGi represents the global pair centerline angle of pair i, θGi−2 represents the global pair centerline angle of pair i−2, and αi represents the angle between the centerline defined by centers of pairs i and i−1, and another centerline defined by centers of pairs i−1 and i−2.

A method of making a round-flat twisted pair cable assembly, comprising steps of:

• providing a plurality of twisted pairs in a juxtaposed manner;
• rolling said twisted pairs in an axial direction parallel to a extension direction of said twisted pairs;
• wherein
• each of said twisted pairs defining a local phase offset angle with regard to a neighboring twisted pair, and a global pair centerline angle with regard to a global horizontal axis, said twisted pairs being arranged in one of two following ways:
• (1) θGi=½ξ[1+(−1)i]+(−1) i−1η−[Σαj+(−1)iΣ(−1)jαj] under a condition of j=2 to i;
• wherein i and j are integrals, θGi represents the global pair centerline angle of pair i, ξ represents the local phase offset angle between pair i and pair i−1, η represents the global pair centerline angle of pair 1, and αj represents the angle between the centerline defined by centers of pairs j and j−1, and another centerline defined by centers of pairs j−1 and j−2;
• and
• (2)θGi=θGi−2−2αi;
• wherein θGi represents the global pair centerline angle of pair i, θGi−2 represents the global pair centerline angle of pair i−2, and αi represents the angle between the centerline defined by centers of pairs i and i−1, and another centerline defined by centers of pairs i−1 and i−2.
