Optical fiber cable used has a loss of 0.2dB/Km and in order to neutralize this loss,
optical amplifier having a gain of 20 dB is used.

Researchers are exploring their applications in many fields such as optoelectronic and photovoltaic devices,
optical amplifier media, probing, and imaging.
The MS9740A, Goto said, supports multiple application measurement modes (for a device such as a DFB-LD, FP-LD, LED, or multichannel
optical amplifier and to make PMD and WDM measurements, for example).
One of the most usable in the contemporary submarine and long-haul terrestrial networks is the distributed Raman amplifiers (DRAs) used stimulated Raman scattering (SRS) effect, which has many advantages: stimulated Raman amplification can occur in any fiber at any signal wavelength by proper choice of the pump wavelength; the Raman gain process is very fast and the effective noise figure (NF) of DRA is smaller than the one of Erbium-doped fiber amplifier (EDFA) and/or the semiconductor
optical amplifier [2,3].
