Present methods for underwater communication involve fiber optics, acoustics, induction modems, or more recently, high-powered optical links. Although fiber optics provides high bandwidths, they are expensive, bulky, difficult to maneuver & deploy. Furthermore, wired networks require a connection to some central, powered entity which is only available in a boat or on-shore. This is not ideal for deep- ocean or prolonged underwater operations. Wireless acoustics are suitable for low-bandwidth applications, but they are not able to form large networks as the channel capacity is relatively limited. In addition, acoustics have been shown to be intrusive to the surrounding ecosystem. In this proposal, the team proposes the Optical Modem Module (OMM) wireless underwater telecommunications device that allows for high-speed, low power communication in a distributed underwater network. The OMM can operate free of any cabling, communicating for well over a year with a standard deep-sea battery.The OMM technology is positioned to meet a market void in high speed serial data transfer in low cost links and dense networks used in sub-mesoscale monitoring (1 km area) application. The OMM has gathered significant interest from ocean science, industry, and defense. This underwater optical network technology has gathered interest from oil & gas industries such as BP and ExxonMobil, ocean science organizations such as the Schmidt Ocean Institute and the Ocean Observatories Initiative, oceanic system integrators such as MacArtney and McLane, and defense contractors including BAE Systems and L3 Communications. The demonstration product and market research will quantify the ocean science community's need to communicate using low-power over a secure channel at high speeds underwater, interfacing with existing infrastructure such as sensors or moorings to other mobile or floating platforms.

目前的水下通信方法包括光纤、声学、感应调制解调器，或者最近的高功率光链路。虽然光纤提供了高带宽，但它们昂贵、笨重、难以操纵部署。此外，有线网络需要连接到某个中央供电实体，这只能在船上或岸上使用。这对于深海或长时间的水下作业来说并不理想。无线声学适用于低带宽应用，但由于信道容量相对有限，它们无法形成大型网络。此外，声学已被证明是侵入周围的生态系统。 在该提案中，该团队提出了光调制解调器模块（OMM）无线水下电信设备，该设备允许在分布式水下网络中进行高速，低功耗通信。OMM可以在没有任何电缆的情况下运行，使用标准深海电池进行一年多的通信。OMM技术的定位是满足亚中尺度监测（1公里区域）应用中低成本链路和密集网络中高速串行数据传输的市场空白。 OMM已经引起了海洋科学、工业和国防的极大兴趣。这种水下光学网络技术已经吸引了石油天然气行业（如BP和ExxonMobil）、海洋科学组织（如施密特海洋研究所和海洋观测站计划）、海洋系统集成商（如MacArtney和McLane）以及国防承包商（包括BAE系统公司和L3通信公司）的兴趣。该演示产品和市场研究将量化海洋科学界的需求，即在水下高速使用低功率通过安全信道进行通信，与现有基础设施（如传感器或系泊设备）连接到其他移动的或浮动平台。
