Disadvantages of Metal Optical Cables
Unlike fiber optic cables, which do not conduct electricity, copper cables can become dangerous in the event of electrical faults or physical damage. Proper installation and maintenance are crucial to mitigate these risks, but they add to the overall effort and cost. But how do you decide which. Cables are bigger in diameter more expensive compared to UTP or coaxial cable. Used in harsh cold and hot environments. Unshielded twisted pair cable uses no additional shielding like mesh or aluminum foil which adds. Immunity to EMI – Signals travel photonicly, not electrically. Higher S/N and lower BER – Thanks to a cleaner medium, optical systems exhibit orders of magnitude fewer errors. Copper has fundamental limitations due to: Capacitive and inductive dispersion – Higher frequencies exacerbate losses.
