Abstract
Adapters for interconnecting optical fiber lines, including optical amplifiers, with optical transmitters and receivers in which the operating parameters of the optical amplifiers are different from the operating parameters of the transmitters and receivers. The adapters convert the optical signals from a transmitter to those within the operating parameters of the optical amplifier and convert the optical signals from an optical amplifier to those within the operating parameters of the receiver. The adapter receiving the optical signals from the transmitter also has provision for inserting service signals and the adapter receiving signals from an optical amplifier has provision for separating the optical signals from the service signals. Also, switching devices for changing transmitters and/or receivers or lines in the event of component failures.
