Raman Amplifier, Rackmount
The Optilab RA-R Raman Amplifiers are optical fiber amplifiers that are designed to recover optical loss incurred in optical fiber, thus extending the transmission distance. The RA-R is designed to amplify optical signals in ultra long-haul DWDM networks, and can also be incorporated into HFC/CATV networks to increase the transmission range of analog and digital channels. Unlike EDFAs, Raman Amplifiers are based on Raman amplification that occurs during the back scattering wherein the single mode optical fiber in the link itself acts as the gain medium. RA-R Raman Amplifiers are typically installed in the mid-stream of a signal or placed before receivers to increase the optical power level signals. Utilizing a multiple high-power pump laser design, the RA-R provide very broad operating wavelength range, constant optical gain, and effectively reduce noise figures in the link.
