31 Are Terrestrial and Submarine Fundamentally Different? Technology has converged dramatically over the past few years FEC, coherent, modulation format... Optical transmission is fundamentally the same. Actually, tranmission is easier over a wet fiber plant: Uniform fiber type/vintage Uniform span length Zero optical connector loss Lower margins The submerged equipment technology is specific. Operational aspects have differences Xtera Communications, Inc. Proprietary 31
