There are cases when a slip ring must be utilized to carry the conductors of copper transmission line (cable) from a rotating platform to a stationary structure. The sharp growth in the use of Gigabit Ethernet has sparked a renewed interest in the ability of slip rings to function within a CAT 5 or CAT 6 network environment. Slip ring designers are able to meet the challenge of more exacting performance parameters with innovative methods of matching impedance, controlling crosstalk, and managing losses.
