Abstract: 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.

Abstract: Example containers are provided to retain and cool electronic devices in environments where power and/or coolant (e.g., airflow) is limited or finite. In examples, a container can include a housing and a conduit system. The housing can include a plurality of sides including a front side and a back side, and can be structured to retain at least a first computing device. In addition, the housing can provide for a first and second inlet opening and a first and second outlet opening on the back side of the container. The conduit system can be provided within the housing to guide the airflow received from each of the first and second outlet openings through an interior volume of the container to cause the airflow to exit from each of the first and second outlet openings.
