To protect infrastructures against disasters, promote worker safety, and facilitate automated functions ranging from drilling to wellhead and transport-pipeline operation, oil and gas operators are turning increasingly to fiber-optic-cable suppliers for end-to-end communications and control solutions. Many such solutions include ruggedized cable and connectors, such as those offered by the Optical Cable Corporation, that ensure survival of fiber-based automation/control architectures for onshore and offshore oil and gas operations, even in the harshest environments. As fiber-optic cable emerges as the medium of choice in many industrial arenas, the DIN rail enclosure plays an increasingly important role. Mounted to a standard DIN rail—the metal rail used to mount various electrical components (e.g., terminal blocks, motor starters, circuit breakers) in a control cabinet—a DIN rail enclosure provides a central location where external and internal wiring can be connected quickly and efficiently. This type of enclosure is ideal for production applications and the industrial automation side of businesses. Today, the oil and gas industry is turning from highly proprietary communications systems to the more enterprise-wide prevalent Ethernet communications protocol through fiber-optic cable. The appropriate DIN rail enclosure provides an optimal connection for fiber cable that can be terminated in a fixed position.
