Long-haul pipeline fiber optic systems provide high-bandwidth communication for SCADA, leak detection, security monitoring, and voice services along natural gas, crude oil, and liquids pipelines spanning hundreds of miles. Tracking PIGs is important, as they can get stuck from time to time, and knowing the location of a stuck brations in the vicinity of the pipeline. The pipe hole resources of underground communication pipelines are the basic communication resources that operators are in short supply. Except for newly built roads and roads in development zones, the occupancy rate of pipe holes on other roads is generally high. Electric Conduit Construction plays a key role in adding resiliency to the control systems by installing, testing, and terminating fiber optic cable for devices and communications.
