　　RA series Raman Amplifiers are optical fiber amplifier that designed to recover optical loss incurred in optical fiber and thus extending the transmission distance. RA series is designed to amplify optical signals in ultra long-haul DWDM networks. RA 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 Scattering Raman Amplification which uses the single mode optical fiber in the link itself as the amplification medium. RA series Raman Amplifiers are typically installed in the mid-stream of signal or placed before receivers to increase the optical power level signals. Utilizing an high-power, multiple pump lasers design, RA series provide very broad operating wavelength range, constant optical gain, and effectively reduce noise figures in the link.

　　It is an ideal solution for extending the transmission range of 10G/40G DWDM networks without the installation of costly repeater. By using a combination of EDFA and RA, HFC/CATV networks operator can extend the transmission distance of analog channels and QAM digitals signal up to 250km.

　　RA series Raman Amplifiers are constructed with Telcordia-qualified components to ensure 15+ years of continuous operating life. They are backed by our standard 3 year limited product warranty. Our technical team provide in-house technical support for networks installation.
