Applied Technology Review: Specials Magazine

Subsea industries operating in extreme ocean conditions require rugged, reliable fiber optic wet mate connectors. Whether it’s oil and gas, renewable energy, or defense, these connectors are essential for uninterrupted data transmission. However, today’s traditional solutions often fall short. Designed for a simpler era, most can accommodate at most 1 to 12 optical fibers and lack the scalability needed to meet modern demands. Additionally, they are prone to misalignment during mating, leaving them vulnerable to contamination by sand and grit, which compromises performance and reliability. The demand for high mateability, centerline actuation, and debris-resistant double seals is greater than ever. Meeting these requirements demands top-tier engineering and R&D expertise, which significantly narrows the field of capable providers. What most saw as an obstacle, Deeplinc envisioned as an opportunity to innovate and set a new standard. A PIONEER IN SUBSEA CONNECTIVITY SOLUTIONS Deeplinc offers an exceptional portfolio of connectors that meet exacting standards. Its product range caters to diverse industry needs while pushing the boundaries of underwater fiber optic technology. Deeplinc has developed a novel, compact fiber optic wet-mate connector capable of supporting up to 48 fibers in small configurations and scaling up to 144 in larger designs, combining robustness with flexibility.

The Latest Advancements in Submarine Optical Fiber Technology

The undersea world has always been a frontier of mystery and marvel, but in the 21st century, it has become a linchpin for global connectivity. Submarine optical fiber cables, often likened to the nervous system of the internet, are undergoing transformative advancements, promising faster, more resilient, and greener solutions for the ever-growing data demands of our world. The relentless surge in data consumption, driven by 5G, IoT, and cloud services, has pushed researchers and manufacturers to rethink traditional cable architectures. One of the most significant breakthroughs in recent years is the adoption of space-division multiplexing (SDM). Unlike older technologies that relied on maximizing individual fiber pair capacity, SDM increases the number of fiber pairs within a single cable, improving both capacity and energy efficiency. Current projects aim to deploy cables with up to 32 fiber pairs, far surpassing the previous standard of 12 to 16 pairs. Simultaneously, advances in coherent optical technology have enhanced the ability to transmit data over vast distances without signal degradation. Utilizing new modulation formats and higher-order constellation schemes, cables can now achieve capacities exceeding 800 terabits per second (Tbps), a staggering figure that underscores the progress in optical signal processing. Modern submarine cables are being engineered to withstand harsher environments and deeper waters. The introduction of bend-insensitive fibers and improved armoring ensures these cables remain operational even under extreme pressures or in regions prone to geological activity. Innovations in coating materials have also reduced cable attenuation, leading to more efficient long-distance data transmission. In this edition, we have featured Deeplinc. The company offers an exceptional portfolio of connectors that meet exacting standards. Its product range caters to diverse industry needs while pushing the boundaries of underwater fiber optic technology.
