摘要： A subsea wellhead system includes: a hanger including a first fiber optic cable; a tree including a second fiber optic cable; a seal sub configured to be coupled to the tree and engaged with the hanger, the seal sub including a fiber optic communications line configured to be communicatively coupled to the first and second fiber optic cables; a transducer configured to be disposed at a downhole location and configured to be communicatively coupled to the first fiber optic cable; a first photodetector disposed in the hanger and configured to convert a light signal traveling through the first fiber optic cable from downhole to an electrical signal communicated to the electrical connection; and a first optical transmitter disposed in the seal sub and configured to convert the electrical signal traveling through the electrical connection into a light signal communicated to the second fiber optic cable.

摘要： Systems and methods for real-time monitoring of well conditions and actuation of downhole equipment are provided. A subsea wellhead system comprises a tubing hanger landed in a wellhead, wherein the tubing hanger comprises a first fiber optic cable; a tree landed on the tubing hanger, wherein the tree comprises a second fiber optic cable; a transducer disposed at a downhole location, wherein the first fiber optic cable is communicatively coupled to the transducer and extends between the transducer and the seal sub; and a seal sub, wherein the seal sub is landed in the tubing hanger, wherein the seal sub comprises: a fiber optic communications line that is communicatively coupled to the first fiber optic cable and the second fiber optic cable; wherein the seal sub and the tubing hanger form an electrical connection regardless of an orientation of the tubing hanger relative to the tree.
