Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Physical Medium Dependent sublayers or PMDs further help to define physical layer specifications for Fast Ethernet, Gigabit Ethernet and 10 Gigabit Ethernet. These sublayers define physical layer specifications in Gigabit and 10 Gigabit Ethernet transmissions. It is responsible for the transmission and reception of individual bits on a physical medium. These responsibilities encompass bit timing, signal encoding, interacting with the physical medium, and the cable or wire itself.In addition, for cable modems (CM) Physical Medium Dependent sublayers or PMDs defines the physical sub-layer which also includes the MPEG sub-layer.
