Abstract

A system including an erbium doped fiber amplifier (EDFA), comprising a length of erbium doped fiber having a first end and a second end, an isolator wavelength division multiplexer (IWDM) comprising an output optically connected at an optical connection with the first end of the erbium doped fiber, wherein the optical connection with the first end of the erbium doped fiber is continuous between the IWDM and the first end of the erbium doped fiber, and an isolator comprising an input optically connected at an optical connection with the second end of the erbium doped fiber.
