ABSTRACT:
An optical amplifier (1) includes optical components including at least one optical amplifying active fiber and a pump laser supplying pumping power to the amplifying fiber through an optical coupler, light guide sections (14) for connecting the optical components, and electronic and electrical power supply and control components (41,42). The amplifier is characterized in that it includes:
an optical unit (15) including all the optical components (2-13) and the connection light guide sections (14),
an electronic unit (16) including all the electronic and electrical components (41,42) and being separate from the optical unit (15),
a plate between the optical unit and the electronic unit; and
electrical interconnections (43,44) between the optical unit (15) and the electronic unit (16).
The clear separation of the electronic components (41,42) from the optical components (2-13) affords size reductions and rationalization of the amplifier (1) implementation procedure.
