Non-repeatered undersea lightwave transmission links, whose signals don't require periodic amplification or regeneration, have historically been deployed: — As part of larger, undersea networks that use repeaters, and — 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: — The technologies and products AT&T Submarine Systems, Inc. (AT&T-SSI) is developing for this market, — Future trends in non-repeatered technology and system design, and — Actual and planned system deployment of undersea optical cable throughout the world. |
