Abstract:
1. An optical amplifier module containing at least one optical amplifier including at least one erbium-doped fiber amplifier, said module comprising: an internal housing having an outer dimension less than about 15 cm×50 cm, said internal housing including: a pair of opposing end faces each having a retaining element for retaining the internal housing within an outer housing of an undersea optical fiber factory cable joint; a sidewall interconnecting said opposing end faces and extending between said opposing end faces in a longitudinal direction, said sidewall including a receptacle portion having a plurality of thru-holes each being sized to receive a passive optical component employed in an optical amplifier; at least one circuit board on which reside electronics associated with the optical amplifier; and an isolated electrical path for providing electrical power received from a conductor in at least one optical fiber cable to the at least one circuit board.
