This paper summarizes a new application technology in advanced optical transmission amplifier development and a series of successful field-trials for "hut-skipping" line architecture using hybrid Raman/Erbium-Doped-Fiber-Amplifiers (EDFA). The trials were conducted to show that the application for hut-skipped ultra long-haul (ULH) at 10-40 GB/s mixing over 1600 km linear field fibers with an average span loss of 38 DB (160 km/span) is possible. The goal was to develop a new optical amplifier which can handle 10G/s and 40G/s co-propagating on the same fiber and achieve excellent performance in metro, regional, and ULH networks. This new amplifier architecture design, while useful in the local, regional and long haul networks, is even more important in the ULH network, where it can significantly reduce network costs, simplify line architectures, and minimize system maintenance requirements. The ability to utilize EDFA/Raman rather than traditional EDFA amplifiers to eliminate traditional short span (about 80 km) line architecture design was due to three characteristics; 1) a much higher total amplifier effective gain 2) a much lower amplifier effective noise figure and 3) a much higher amplifier OSNR.
