Abstract: A system for communicating between a surface facility and a subsea production control system includes a communications device proximate the water surface. The water surface communications device has at least one communication interface. A communications device is functionally associated with a wellhead or subsea structure proximate the water bottom. The water bottom communications device has at least one communication interface. A communication channel extends between the surface communication device and the water bottom communication device. A multiplexer is functionally coupled to the communication interface on each of the surface and water bottom communication devices. At least two remote devices are functionally coupled to the water bottom multiplexer. The remote devices comprise at least one of a sensor and a control. At least two corresponding devices are coupled to the surface multiplexer.

Abstract: A system for use in a subsea environment includes at least one fiber optic cable for connection to surface equipment, and a subsea optical junction assembly connected to the at least one fiber optic cable. The system further includes subsea components, and plural fiber optic cables connected to corresponding subsea components. The subsea optical junction assembly couples the at least one fiber optic cable for connection with the surface equipment to the plural fiber optic cables connected to the subsea components.

Abstract: An apparatus includes a housing, a first connection interface and an optical amplifier. The housing receives a fiber optic line and an electrical line. The first connection interface is located at least partially inside the housing and is exposed outside of the housing to couple the fiber optic line and the electrical line to a second connection interface. The optical amplifier is located inside the housing and is coupled to the fiber optic line. The optical amplifier receives power from the electrical line.
