Undersea Non-Repeatered Technologies, Challenges, and Products

摘要

Non-repeatered undersea lightwave transmission links, whose signals don't require periodic amplification or regeneration, have historically been deployed: 1. As part of larger, undersea networks that use repeaters, and 2. In domestic non-repeatered systems installed either between islands or looping a shoreline. With the world's transoceanic cable network rapidly expanding into a global undersea network—and transoceanic systems connected to regional systems, which are then connected to domestic systems—the market is moving towards an increased percentage of short-haul, non-repeatered systems. This paper discusses: 3. The technologies and products AT & T Submarine Systems, Inc. (AT & T-SSI) is developing for this market, 4. Future trends in non-repeatered technology and system design, and 5. Actual and planned system deployment of undersea optical cable throughout the world.
