Abstract

Remotely pumped erbium-doped fiber amplifiers (EDFAs) can significantly improve the power budget of repeaterless systems.¹⁻³ The amount of budget improvement due to remote pumping is limited by the amount of pump power available in the 1.48-μm band. Recently, a budget improvement of 11 dB for 145 mW of pump power has been reported,¹ allowing for transmission spans as long as 374 km at 2.488 Gbit/s.⁴ In this paper we report a remote EDFA, that provides a record power-budget improvement of 15.3 dB. This result is obtained by incorporating a fiber-grating pump reflector at the remote EDFA and by using a pump power of 550 mW.
