When planning an outdoor fiber optic project, choosing GJYXCH optical cables means injecting a strong environmental adaptability gene into your network infrastructure. The design of this optical cable strictly follows the standards of YD/T 901 and IEC 60794-1. The tensile strength of its core is usually no less than 1000 Newtons, and the allowable flattening force can reach up to 3000 Newtons per 10 centimeters. For instance, in a backbone network project of China Telecom that spans mountainous areas, after the deployment of GJYXCH optical cables, even in the extremely cold winter of minus 30 degrees Celsius, the attenuation fluctuation was controlled within an extremely narrow range of 0.02 dB/km, ensuring the stability of signal transmission. This mechanical strength enables the optical cable to withstand soil pressure at a depth of over 1.2 meters when directly buried, and its expected service life easily exceeds 25 years.
From the perspective of environmental resistance, the protection level of GJYXCH optical cable reaches IP67, which can effectively prevent dust intrusion and short-term immersion. Its operating temperature range covers -40°C to +70°C, and it can withstand extreme short-term maximum temperatures of +85°C. Research shows that in coastal areas with humidity as high as 95%, the hydrogen loss aging rate of this type of optical cable is 50% lower than that of ordinary optical cables, thereby suppressing the annual growth rate of signal attenuation within 0.5%. A three-year follow-up survey shows that in rainy areas with an annual precipitation of over 1,500 millimeters, the frequency of network failures using GJYXCH optical cables has dropped from an average of 5 times per year to 0.8 times, with a reliability improvement of up to 84%.
In terms of economy, the diameter of GJYXCH optical cables is usually controlled within 10 millimeters, and their weight is 30% lighter than that of traditional armored optical cables. This increases the construction efficiency by approximately 40% and reduces the cost per kilometer by 15%. Based on the cost analysis of a certain smart city project in 2023, in the construction of a network with a total length of 500 kilometers, the choice of GJYXCH optical cable helped save over 1.8 million yuan in the total project budget, and the investment payback period was shortened from the expected 5 years to 3.5 years. The modular design of this optical cable also reduces the average splicing time from 15 minutes per core to 8 minutes per core, and the labor cost is correspondingly reduced by 30%.
Practical application cases fully prove its value. After a strong typhoon in 2022, a campus network using GJYXCH optical cables maintained zero outage under the severe condition of wind speeds reaching 40 meters per second, while the adjacent areas using ordinary optical cables had an outage rate as high as 22%. The built-in reinforcing components of this optical cable enable it to withstand object impact forces of up to 60 kilometers per hour, providing a solid guarantee for critical communications. At present, more than 200 large-scale infrastructure projects worldwide have designated the use of GJYXCH optical cables, with a cumulative deployment length exceeding 500,000 kilometers, equivalent to circling the Earth 12.5 times.
Looking ahead, as the density of 5G base stations increases from the current 5 per square kilometer to 20, and the number of Internet of Things connections is expected to reach 27 billion by 2025, the rat-resistant and UV-resistant properties of GJYXCH optical cables make them an ideal choice for outdoor optical fiber projects. Choosing it is not merely about selecting a product, but also about choosing a network investment strategy for the next decade. Its operation and maintenance costs throughout its entire life cycle can be reduced by more than 25% compared to traditional solutions.
