We proposed a remote pumped bidirectional C+L band fiber amplifier for wavelength division multiplexing (WDM) passive optical network (PON). A high-reflectivity pump reflector using three cascading fiber Bragg gratings (FBGs) is designed to reflect the residual pump power for L band amplification. Both the gains for C band and L band are larger than 10.0 dB under −10 dBm launched power. Using the...
A bidirectional wavelength reconfigurable optical network is proposed. A remote pumped Erbium doped fiber amplifier and high-reflectivity tunable fiber Bragg gratings (TFBGs) are used in this wavelength reconfigurable fiber module. 10 Gb/s per channel over 20 km fiber span is used to verify the metro-network-range system performance. The power penalty is less than 1 dB when compares to the back to...
All-optical 2R regeneration of a 160-Gbit/s RZ-OOK signal is demonstrated in a fiber optical parametric amplifier using a highly nonlinear fiber with the data as pump. Bit error rate bathtub curves validate the regeneration performance.
In this paper, a bidirectional hybrid fiber amplifiers is proposed and experimentally demonstrated. The hybrid amplifiers include a C-band erbium-doped fiber amplifier (EDFA) and an L-band Raman fiber amplifier (RFA). A single-wavelength pump source at 1495 nm is pumped shared to both the EDFA and the RFA. Under the pump power of 500 mW, the average gains are about 11.3 dB for the C band EDFA and...
We proposed a hybrid C+L band fiber amplifier bridged with double-pass dispersion compensators. Power equalization among C+L band channels is realized by adjusting the FBGs reflectivity. Pumping efficiency is improved by recycling residual pump power.
