Thulium-doped optical Fiber enhancers (TDFA) are advanced to cover the optical media transmission Wavelength Division Multiplexing (WDM) information transmission in the envisioned the band (800-1800 nm) with up to 6.5dB increment and noise figure as low as 2.6 dB. We existing the first in-band diode-siphoned thulium-doped fiber amplifier (TDFAs) operational in the wavelength locale and test their appropriateness as high request enhancers in possible coming media transmission frameworks.
