The Prevalence and Application of GYFXTY Outdoor Fiber Cable in Russia

3. Technical Features of GYFXTY​

3.1 Construction​

Fibers in GYFXTY are positioned in a central tube made of high - modulus plastic. This material provides excellent mechanical protection to the fibers. The central tube is filled with tube gel, which serves multiple purposes. Firstly, it protects the fibers from moisture and mechanical stress. Secondly, it helps in reducing micro - bending losses, ensuring stable optical transmission.​

The tube is armored with aramid yarns and water - blocking yarns. Aramid yarns are known for their high strength - to - weight ratio. They significantly enhance the tensile strength of the cable, allowing it to withstand the forces exerted during installation and in harsh environmental conditions. The water - blocking yarns, on the other hand, prevent water ingress into the cable, which is crucial for maintaining the integrity of the fiber optic transmission.​

Finally, a PE (Polyethylene) jacket is extruded over the armored structure. The PE jacket provides additional protection against environmental factors such as UV radiation, chemicals, and abrasion. It also helps in making the cable resistant to rodents, which can be a problem in some outdoor installations.​

4. Application Scenarios in Russia​

4.1 Duct Installation​

In urban areas of Russia, such as Moscow and St. Petersburg, there is a complex network of underground ducts. GYFXTY is an ideal choice for duct installation. Its compact design with a diameter of 6.8 mm allows it to be easily inserted into existing ducts. The cable's excellent flexibility enables it to navigate through the bends and curves of the duct system. The water - blocking and crush - resistant features ensure that the cable remains intact in the often - damp and crowded duct environment. In these major cities, where there is a high density of buildings and a large number of communication service providers, the use of GYFXTY in duct installation helps in providing reliable high - speed communication connections to businesses, residential buildings, and public facilities.​

4.2 Non - Self - supporting Aerial Installation​

In rural and remote areas of Russia, where the population density is low and laying underground cables may be costly and time - consuming, non - self - supporting aerial installation of GYFXTY is a common practice. The aramid - armored structure of the cable provides the necessary strength to withstand the forces of wind, ice, and snow. In regions like Siberia, where winters can be extremely harsh with strong winds and heavy snowfall, the cable's high tensile strength ensures that it remains suspended without breaking. Aerial installation also allows for quick deployment, which is crucial for bringing broadband access to remote areas. For example, in small villages in the Far East of Russia, GYFXTY has been installed aerially to connect local schools, medical centers, and homes to the national communication network, enabling access to online education, telemedicine, and e - commerce services.

5. A Case Study in Russia​

In the city of Yekaterinburg, a major industrial and cultural center in the Urals region of Russia, a large - scale fiber optic network upgrade project was carried out. The city's existing communication infrastructure was unable to meet the growing demands of its population, especially with the increasing number of smart city initiatives and the expansion of digital services.​

The project aimed to provide high - speed broadband access to all residential and commercial areas in the city. GYFXTY was selected as the primary fiber optic cable for the project due to its suitability for the local environment and its cost - effectiveness.​

During the project, a significant portion of the cable was installed in ducts in the city center. The compact size and flexibility of GYFXTY made it easy to work with in the complex duct network. However, in some areas where the ducts were damaged or non - existent, non - self - supporting aerial installation was adopted.​

One of the challenges faced during the installation was the harsh winter conditions. Yekaterinburg experiences long and cold winters with temperatures dropping well below - 20℃. The installation teams had to take extra precautions to ensure that the cable was not damaged during handling and installation in such cold temperatures. The GYFXTY cable, with its ability to operate in low - temperature environments, performed well. The installation teams used special equipment to handle the cable gently and ensure proper tension during aerial installation.​

Another challenge was the presence of some industrial areas with high levels of electromagnetic interference. The non - metallic components of GYFXTY, such as the high - modulus plastic central tube and the PE jacket, provided good resistance to electromagnetic interference, ensuring stable optical transmission.​

After the completion of the project, the results were remarkable. The average broadband speed in Yekaterinburg increased significantly, from an average of 50 Mbps to over 1 Gbps in many areas. This improvement has had a positive impact on various aspects of the city's development. Businesses have been able to operate more efficiently, with faster data transfer speeds enabling real - time communication, cloud - based services, and e - commerce transactions. Residents now have access to high - quality online entertainment, educational resources, and telemedicine services. The city has also become more attractive for new investments in the digital technology sector, as the improved communication infrastructure provides a solid foundation for innovation and growth.

6. Conclusion​

The GYFXTY Outdoor Fiber Cable has proven to be a highly suitable and popular choice in the Russian market. Its technical features, such as good mechanical and thermal performance, hydrolysis - resistant loose tube, and effective protection mechanisms, make it well - adapted to the diverse environmental conditions in Russia. The application scenarios of duct and non - self - supporting aerial installation cover both urban and rural areas, meeting the communication needs of different regions. The case study in Yekaterinburg demonstrates the successful implementation of GYFXTY in a large - scale fiber optic network upgrade project, resulting in significant improvements in the city's communication capabilities. As Russia continues to invest in its communication infrastructure development, the demand for GYFXTY is likely to grow further, playing an increasingly important role in the country's digital transformation journey.
