Abstract Thulium is basically a rare earth element that can be used as a dopant ma terial in amplifiers designed to particularly operate in S-band (1460 nm-1530 nm) region. Another important category of optical amplifiers is fiber Raman amplifier (FRA), which have the capability to operate in any communication band, provided pump power centered at appropriate wavelength is injected into it. In this work, we have simulated TDFA-FRA hybrid amplifiers operating in cascaded and parallel configuration at 0.8 nm, 0.4 nm and 0.2 nm channel spacings. A total of 5 continuous wave (CW) lasers operating at 1000 nm, 1040 nm, 1390 nm, 1410 nm and 1450 nm have been used for pumping purposes in the proposed TDFA-FRA hybrid amplifier configured in cascade as well as parallel configuration. It has been observed that enhanced gain > 19 dB in the region 1460 nm to 1570 nm (110 nm) region has been attained by employing proposed multipumped TDFA-FRA hybrid amplifier..
