  • Does the reinforcing core of indoor optical cable need to be grounded

    Does the reinforcing core of indoor optical cable need to be grounded

    Fiber optic cable transmits data as light through glass or plastic strands, which means the fiber core itself carries no electrical current and requires no grounding.
