Add/Drop Multiplexer: A synchronous transmission network (SDH or Sonet) can carry multiple channels. An Add/Drop Multiplexer is a device that adds (inserts) or drops (removes) lower-data-rate channel traffic from the higher-rate aggregated channel.

Acronym for: Add-drop multiplexer

Add drop multiplexer optronics that allow for lower speed SONET services to be aggregated or multiplexed to higher speed SONET services. These optronics are used to provide SONET-based Bandwidth Infrastructure services over fiber
