Abstract:

Fiber-based optical amplifiers such as the erbium-doped fiber amplifierEDFA and Raman fiber amplifier RFA offer the attraction of high gain, low coupling loss and polarization insensitivity. Hence their use in combination to form a nonregenerative repeaterNRR deserves consideration. This paper provides a theoretical analysis and gain optimization for this form of NRR. This arrangement is found to provide higher gain than either an EDFA or a RFA repeater alone and offer the potential of extending the NRR span to over 300 km.
