Protocol transparent optical amplification for C-Band wavelengths to achieve greater transmission distances. It’s one of the most recent technology breakthrough in fiber communications, optical amplifiers based on Erbium dopped fiber (EDFAs) are widely used in submarine, inter-city and even metropolitan networks in order to compensate losses and to enable long distance transport. Without EDFAs, we would not have today’s highly efficient Dense Wavelength Division Multiplexing (DWDM) networks. Danriver CTX1025 family optical infrastructure product of optical amplification for WDM and single wavelength optical transmission interconnect links, leveraging elements of the carrier-centric variety optical amplifier, for longer reaches extending to metro/regional Ethernet data center and service provider network interconnects.(/en)
