MODE FIELD DIAMETER - In single-mode fiber, the region in which light propagates is larger than the glass core diameter. This mode field diameter is a measured value and often listed as a requirement with core diameter in fiber specifications.
MODES - Individual paths in optical waveguides. Single-mode fiber has only one mode, the fundamental mode, while multi-mode fiber has several hundred modes. The upper limit to the number of modes is determined by the core diameter of the waveguide.
MODULUS OF ELASTICITY - The ratio of stress to strain in an elastic material.
MOISTURE RESISTANCE - Ability of a material to resist absorbing moisture from the air or when immersed in water.
MOLDED PLUG - A connector, male or female, molded on either end of a cord or cable.
MONOMER - The basic chemical unit used in building a polymer.
MP - Abbreviation for multipurpose cable.
MPa - Abbreviation for mega pascal (106 pascals), the metric unit of pressure.
MPG - Abbreviation for multipurpose general purpose cable.
MPP - Abbreviation for multipurpose plenum cable.
MPR - Abbreviation for multipurpose riser cable.
MSHA - Abbreviation for Mining Safety and Health Administration.
