ABSTRACT:
A high-speed data communications cable has geometrically concentric layers of twisted pairs of wires. A first, innermost layer includes a first twisted pair of wires having a unique lay length and a first and second dielectric filler. A second geometrically concentric layer is formed about the innermost layer and includes 9 twisted pairs of wires having 5 lay lengths. A third geometrically concentric layer is formed about the second layer and includes 25 twisted pairs of wires having 5 lay lengths. The first, second and third layers are enclosed in a thermoplastic jacket resulting in a flexible data cable with a minimal diameter. Additional layers of more twisted pairs of wires may also be used. A plurality of communication cables may also be commonly sheathed.
