Definition - What does Silver Satin mean?
Silver satin is a type of cable used to connect a phone to a wall jack. The wires in a silver satin cable run side by side, but are not configured as twisted pairs. This results in high degrees of crosstalk over the line. Silver satin cable wiring is most often used for low-speed voice applications such as a telephone line, but because of the possibility of interference from other signals it is not suited to high-speed network connections.
