An optimized design for a broadband Raman optical amplifier in standard single-mode fiber covering the C and L bands is presented. to be used in combination with wideband optical phase conjugation (OPC) nonlinearity compensation. The use of two Raman pumps and fiber Bragg grating reflectors at different wavelengths for the transmitted (C band) and conjugated (L band) WDM channels is p... https://pipingrockers.shop/product-category/choline-inositol/
