Performance of 16/spl times/10 gb/s WDM transmissions over 4/spl times/40 km of SMF using linear optical amplifiers combined with Raman-pumped dispersion compensation fibers under dynamic add-drop situations

Linear optical amplifiers combined with dispersion compensating Raman fiber amplifiers were used to successfully transmit sixteen channels of 10-Gb/s wavelength-division-multiplexing signals over four 40-km spans of single-mode fiber. No add-drop-induced penalty was observed after the 160-km transmission when 15 out of 16 channels were dynamically add-dropped.
