Design and implementation of remotely pumped amplifiers in repeaterless transmission systems are being reviewed. Here, we discuss Raman amplifiers, as well as remote pumping of erbium-doped fiber post-and preamplifiers. Since the advent of semiconductor laser-pumped high-power sources Raman amplific
