Distributed sensing fiber optics in concrete

The utilization of distributed fiber optic sensing (DFOS) allows the assessment of strain and temperature distributions continuously along the installed sensing fiber and is widely used for testing of concrete structures to detect and quantify local deficiencies like cracks. [pdf]

How to use a fiber optic coupler to an Ethernet port

Connecting Fiber Optic Cable to Ethernet Port: Carefully insert the fiber optic cable connector into the Ethernet port, aligning the keying mechanism if applicable. Ethernet ports are designed for copper cables (like Cat5e or Cat6), which transmit data using electrical signals. This video will tell you how to make the RJ45 port on the router to use with fiber.
