Are the weight ratios of optical cables and electrical cables the same
Although fiber optic cable has strength member to enhance its tensile and anti-crush mechanical performance, the cable weight is still much lighter than any practical electrical cable. Electrical conductors are much heavier than optical fiber for similar delivery. The main difference between fiber cable and electrical cable is their transmit medium, as we can tell from their name and structures. But there are more aspects of them when compared together. Electrical cable is a device that uses metal as a medium to transmit electrical signals. It often use.
