1. A method for monitoring a Christmas tree assembly installed on a subsea hydrocarbon well, comprising:
- providing an optical feedthrough module operable to communicate through a pressure boundary of the Christmas tree assembly at least one optical signal with a plurality of optical sensors disposed within the Christmas tree assembly for measuring parameters associated with the Christmas tree assembly;
determining a health metric for the Christmas tree assembly based on the parameters measured by the plurality of optical sensors; and
identifying a problem condition with the Christmas tree assembly based on the determined health metric.
