This application describes techniques for testing fiber optic telecommunication systems, such as undersea fiber optic cable systems. Testing terminals may be deployed at a location of terminating equipment for a fiber optic cable. The testing terminals may be operated remotely. The testing terminals may be configured to programmatically test the cable by loading one or more tests and automatically configure the cable's transmitters and receivers based on predetermined loading schemes selected based on the tests to be performed. The testing terminals may iterate over channels and fiber pairs of the cable and may use back-to-back tests to remove artifacts from test results. Using the described techniques, a cable's channels and fiber pairs can be fully characterized in the amount of time afforded for a typical testing schedule, which was not generally possible using conventional testing.

Methods, mediums, and systems for testing fiber optic telecommunication systems

A communication system including a repeatered trunk path and one or more unrepeatered branch segments coupled to the trunk path through associated submarine branching units. Each of the branch segments may be configured to carry at least the same channel capacity as the trunk path and may have a length greater than the average repeater spacing in the trunk path.
