They can weigh between 60 to 200 kg per kilometer (39. 7 to 132 pounds per 1000 feet), depending on the design and materials used. However, some general guidelines can provide a rough estimate: Indoor Fiber Optic Cables: These are typically lighter as they require less protection. In case of Black tube with white marking. Our Aqua jacketed 250 meter (~820 feet) 10 gigabit rated fiber optic cable is terminated with LC (Lucent Connector) connectors on both ends. It is a singlemode fiber (9 micron core) designed to transmit data across long distances at high speeds. The cord is duplex (two fibers) which means it permits. Calculate cable weight from length and weight per meter, or estimate total weight by cable size, material, core count, and insulation.
