Protecting Fiber Cables for Seamless Data Transmission

Fiber optics assumes a pivotal role in communication systems, both onshore and offshore within the subsea industry. By employing light for data transmission instead of electricity, fiber cables facilitate the rapid conveyance of vast amounts of data.

Ensuring the integrity of critical data transfer is contingent upon the constant protection of fiber cables from external elements such as gas, water, mud, and more. For a considerable duration, employing polymers has been a reliable and cost-effective solution.

As the demand for reliability escalates and the need for high-temperature and high-pressure well completions grows, polymers no longer suffice as a sealing solution. The hermetic seal created by glass becomes imperative at every interface between the atmosphere and pressure where fiber connectivity must remain intact. In this evolving landscape, glass stands as the indispensable material, providing the necessary resilience and sealing capability to safeguard fiber cables and ensure seamless data transmission.

Advantages of the G2M Technology

G2M stands for Glass to Metal. Glass demonstrates its superiority through the formation of an exceptionally robust bond with both metal and optical fibers. This robust bonding strength not only secures the integrity of the optical fiber infrastructure but also exceeds the capabilities of conventional materials like epoxy and polymers, presenting an unmatched level of resilience and durability in the industry.

Resistance to Environmental Challenges and Extreme Weather Conditions

In contrast to polymers, glass exhibits remarkable resistance to the dual challenges of moisture and temperature. The G2M Fiber Penetrator can stand temperatures from -18 up to 70 degrees Celsius. Its inherent properties ensure a steadfast performance in diverse environmental conditions, both under and over water, making it the material of choice for applications where reliability is non-negotiable.

Withstands Extreme Pressures

In the challenging subsea and offshore environments, the indispensability of G2M seals becomes apparent at each atmospheric-to-pressure interface, where the continuity of fiber connectivity is of utmost importance. Operating seamlessly under pressures of up to 5,000 psi, G2M technology, reinforced by its glass foundation, excels in providing stability. This stability serves as a testament to its engineering precision, ensuring the steadfastness and operational reliability of the optical fiber infrastructure, even in the most adverse conditions. As industries navigate the intricacies of subsea exploration and offshore applications, G2M seals, with their exceptional stability, emerge as a strategic choice, establishing a reliable and resilient foundation for uninterrupted optical fiber connectivity.

Long Lifespan and Stability

One of the key distinguishing features of G2M technology lies in the long-term stability offered by glass. Unlike materials prone to degradation, glass maintains its structural integrity and functionality over time, providing a solution that is not only reliable but also sustainable for the evolving needs of optical fiber applications. The G2M has a lifespan of up to 30 years.

Why choose glass over polymers /epoxy

In the dynamic landscape of optical fiber technologies, the choice of material plays a pivotal role in determining performance, reliability, and longevity. Glass seal around optical fiber emerges as the superior choice, outclassing epoxy/polymers in several critical aspects.

1. No optical penalty:

The G2M seal has been engineered with precision, ensuring that it not only meets but exceeds optical standards. Rigorous testing and innovative design have led to a seal that yields no optical penalty.

2. Mechanical Strength:

The mechanical strength of glass seal is significantly superior to polymers/epoxy. This robustness is particularly crucial in installations where the optical fiber may be subjected to physical stresses or environmental challenges.

3. Thermal Stability and Resistance:

Glass seal excels in maintaining stability across a broad range of temperatures. In contrast, polymers are susceptible to heat-induced deformation, and epoxy may experience thermal degradation. Glass ensures that the optical fiber infrastructure remains reliable and operational, even in environments with fluctuating temperatures.

4. Resistance to Environmental Factors:

Glass seals are highly resistant to environmental factors such as moisture and chemicals. This resistance contributes to the longevity of the optical fiber network, ensuring consistent performance in diverse conditions. In comparison, polymers may degrade over time when exposed to certain environmental elements.

5. Long-Term Reliability:

The stability and durability of glass make it a reliable long-term investment. Epoxy/polymers may exhibit aging-related issues, leading to a degradation of optical performance. Glass, on the other hand, maintains its structural integrity and optical properties over an extended lifespan.

6. Future-Proof Technology:

Choosing glass seal aligns with a future-proof approach. As technology advances and data transmission requirements evolve, glass can ensure scalability and adaptability to future needs.

Strength, resilience, and stability

In summary, the decision to opt for glass seal over epoxy/polymers is driven by a commitment to performance, mechanical resilience, thermal stability, environmental resistance, long-term reliability, and future adaptability. G2M technology, with its foundation in glass, represents a paradigm shift in the pursuit of excellence in optical fiber infrastructure, offering strength, resilience, and stability.
