Leading the Way in Subsea Cables for Defense

In the ever-evolving landscape of defense technology, Aptiv stands out as a global leader in the manufacturing and supply of subsea cables tailored for the defense industry. As defense contractors continue to advance undersea systems, such as Unmanned Undersea Vehicles (UUVs), Towed Body Arrays, and other critical sensors, the role of high-performance cables becomes increasingly vital. These sophisticated systems are designed to detect or deter advanced threats, and reliable cabling is critical to their proper functioning, whether it’s a tow cable deployed from a ship or submarine, or an Ethernet cable enabling high-definition video transmission.

The Xtreme Cable Family and Water Blocking Technology

Aptiv's Xtreme Cable family is engineered to meet the demanding requirements of undersea applications. The lineup includes:

Xtreme-Cat: High-Speed Network Data and Video Cable

The Xtreme-Cat cable is designed to handle high-speed data transmission, making it ideal for network applications that require rapid and reliable data transfer. This cable is crucial in underwater defense systems where real-time communication and high-definition video are paramount. Whether it’s transmitting data from underwater sensors to a surface vessel or enabling high-resolution video feeds for monitoring and surveillance, the Xtreme-Cat cable ensures seamless connectivity and performance.

Xtreme-Green: Video Inspection Cable

While not equipped with water blocking technology, the Xtreme-Green cable excels in video inspection applications. It is designed for environments where visual inspections are critical, providing clear and precise video feeds. This cable is often used in the inspection of underwater structures, pipelines, and other critical infrastructure, offering defense personnel the ability to conduct thorough visual assessments without the risk of water ingress compromising the integrity of the cable.

Xtreme-Marine: Coaxial Cable for HD/SD Video

The Xtreme-Marine cable is a coaxial cable tailored for high-definition (HD) and standard-definition (SD) video applications. Its robust construction ensures reliable video transmission even in harsh underwater environments. This cable is essential for underwater surveillance systems, providing clear and uninterrupted video feeds that are crucial for monitoring and security operations in defense applications.

Xtreme-Net: Ethernet Cable

Ethernet cables are the backbone of modern communication systems, and the Xtreme-Net cable is no exception. This cable supports high-speed Ethernet connections, ensuring efficient data transfer and network performance. In defense applications, the Xtreme-Net cable is used to establish reliable network connections between underwater devices and surface control systems, facilitating real-time data exchange and operational coordination.

Xtreme-Light: Fiber Optic Cable

The Xtreme-Light cable leverages fiber optic technology to deliver superior data transmission capabilities. Fiber optic cables are known for their high bandwidth and long-distance transmission capabilities, making them ideal for underwater defense systems that require extensive data communication over long distances. The Xtreme-Light cable is used in applications where large volumes of data need to be transmitted quickly and securely, such as in sonar systems, communication networks, and sensor arrays.

Cables with Water Blocking

While cables with jackets do provide some level of moisture protection, the truth is that it does not make that cable waterproof. Aptiv's Xtreme cables use a Depolymized Rubber (DPR) which is effective for subsea/underwater applications and guarantees maximum protection against ingress. The DPR fills in where there is potential for water to ingress, reducing any gaps once the outer jacket is installed.

Understanding Water Blocking in Cables

A common misconception is that all jacketed cables are water-resistant by default. While an outer jacket provides some protection against moisture, it does not render the cable waterproof. This is where water blocking technology becomes essential, particularly for subsea applications where exposure to water is a given.

Dry Water Blocking

Dry water blocking involves wrapping special tapes around the cable’s internal components, positioned just beneath the outer jacket. Upon contact with water, these tapes expand and fill any puncture sites, effectively preventing water ingress. The tapes are typically treated with chemicals that cause the absorbed water to gel or solidify, reducing the likelihood of migration. This technology can significantly extend the lifespan of cables in high-moisture environments where continuous exposure to water is not anticipated.

Gel Water Blocking

Gel water blocking, on the other hand, employs a water-repelling gel applied to the cable’s shield during manufacturing. This gel fills the gaps within the cable’s internal conductors, preventing water migration once the outer jacket is in place. Gel water blocking is recommended for applications where cables are subjected to standing water or used underwater, ensuring comprehensive protection against moisture.

Applications in the Defense Market

Aptiv's subsea cables, equipped with advanced water blocking technology, are indispensable in various defense applications:

• Unmanned Undersea Vehicles (UUVs): High-reliability cables ensure seamless data transmission and power delivery to critical components. The Xtreme-Cat and Xtreme-Light cables, in particular, are essential for maintaining communication and control of UUVs, allowing them to perform reconnaissance, surveillance, and other vital missions.
• Towed Body Arrays: Durable tow cables withstand harsh marine conditions, enabling precise sensor deployment and data collection. The Xtreme-Marine and Xtreme-Net cables are ideal for these applications, providing reliable data transmission and operational durability in challenging underwater environments.
• Subsea Sensors: Reliable Ethernet and fiber optic cables support high-definition video and data transmission, essential for real-time monitoring and analysis. The Xtreme-Cat and Xtreme-Light cables ensure that data from subsea sensors is transmitted accurately and efficiently to surface control systems.
