A 23 channel DWDM system has been setup where it was observed that longer optical link lengths are obtained with EDFA Opt as compared to EDFA Initial.Īgrawal, G.P.: Fiber-optic Communication Systems, 3rd edn. This study enabled to identify optimum parameter set for EDFA in the SP configuration setup with gain (G), figure of merit (FOM) and flattened gain spectrum ( \(\) has been enhanced to 20 nm in the wavelength range from 1540 to 1560 nm. Also, effect of linewidth on EDFA gain spectrum is investigated. Impact of slope efficiency on DFB lasers of different threshold current values was observed. The permissible range of operation of DFB laser and EDFA was identified. Various DFB laser rate equation parameter sets have been extracted with different threshold current values and their suitability to be used in conjunction with EDFA has been investigated in the distributed feedback laser- single pass erbium doped fiber amplifier (DFB- (SP) EDFA) setup. This paper has presented an investigation for influence of DFB laser on the gain behaviour in an EDFA which is pumped by 980 nm. DFB is used in most of the networks because of narrow linewidth, low chirp and low relative intensity noise (RIN).

Distributed feedback laser (DFB) along with erbium doped fiber amplifier (EDFA) have become the key components of the rapidly growing WDM and cable TV optical communication systems.
