The DFRA (Distributed Fiber Raman Amplifier), adopts unique design to produce Distributed signal gain and flat output power while maintaining low noise figure, enabling test capabilities in system or component level manufacturing and characterization, as well as facilitating highly. Distributed amplifiers are an alternative to lump amplifiers in fiber-optic links. For longer fiber-optic links (for long-haul data transmission), one or several fiber amplifiers are usually needed for obtaining a sufficiently high signal power at the receiver and maintaining a high enough.
