FIBER IN METAL TUBES

Self-Supporting Downhole Cable (SDC)

A Downhole Cable for Harsh Environments

The intelligent design of the Self-Supporting Downhole Cable is the standout characteristic of this fiber optic cable. The helical shape of the FIMT locks the EFL in place; this is true even for long vertical installation lengths, where fibers in straight cables usually fall because of gravity.

The outer stranding wires are made of highly corrosion-resistant steel grades, guaranteeing the fiber optic cable’s performance and flexibility even in the harshest environments. The design allows for a separation between the optical fiber and potential copper wiring, making it perfect for integration in hybrid cables.
