Next, we examine the attacks on the physical layer, which are different from attacks on . divided into the following four classifications: □ Most standards list two candlefoot power as the norm for . beams that cover an area with protection. The standards cover four different functional areas: • The Physical Media The Physical Layer Protocol (PHY) defines physical-layer characteristics that are. The existing AIs cover topics such as electrical interfaces, tunable lasers, and and INFi (XFP) are especially relevant to physical layer optical transceivers. fiber optic related standards into four categories, as follows: (1) Components.
