fiber cable

To test it, they injected light into a 2-kilometer-long optical fiber cable, similar to the ones used for optical telecommunication.

The fiber cable formed a loop where the input and output are connected, creating a continuous light path with no breaks, and was precisely wound around an aluminum spool with a diameter of 25 cm to form a coil.

That partnership, announced Monday, is aimed at delivering fiber cable to 10 villages and more than 10,000 people.

They’ve recently either added or upgraded the fiber cable throughout our neighborhood.

Last year, researchers set a new record for DAS length with a next-generation interrogator that detected vibrations at a distance of 120 kilometers on a fiber cable running off Svalbard, the world’s northernmost inhabited island.
