Edit / See: Physical Media Dependent

A sublayer concerned with the bit transfer between two network nodes. It deals with wave shapes, timing recovery, line coding, and electro-optic conversions for fiber based links.

physical medium dependent. Sublayer of the FDDI physical layer that interfaces directly with the physical medium and performs the most basic bit transmission functions of the network. See also PHY.

PMD is a Java source code analyzer. It finds unused variables, empty catch blocks, unnecessary object creation, and more. It includes CPD, a tool to detect chunks of identical code.

An abbreviation for polarization mode dispersion. Learn more about PMD...

Polarization Mode Distortion. The property of the two polarization modes of light to travel with independent but related effects; intrinsic to the fiber but affected by environmental conditions that the fiber is in; it will affect BER in high speed digital systems and will affect distortion in analog CATV systems
