Abstract
A distributed pressure, temperature, strain (DPTS) sensing cable includes at least two slotted fiber optic metal wires each having a slot groove extended along in an outer circumference of the wires to encapsulate optical fibers in the slot grooves. The two slotted fiber optic metal wires have characteristics different from each other.
