Testing the Performance of Fibermart Outdoor Armored Fiber Optic Cables in Harsh Environments

Fiber optic cables are a critical component in modern communication systems, and their performance in harsh environments is crucial. Fibermart outdoor armored fiber optic cables are designed with superior protection to ensure stable operation under various extreme conditions. Before our products hit the market, they undergo rigorous experimental testing and data analysis to guarantee their excellent performance. Here, we present the performance of Fibermart outdoor armored fiber optic cables under various harsh conditions such as high temperature, low temperature, humidity, salt fog, mechanical stress, and UV radiation, verifying their reliability and superiority in extreme conditions.

 

I. Weather Resistance Testing and Results

 

1. High Temperature and Low Temperature Testing

The performance of fiber optic cables can be significantly affected by high and low temperatures. To evaluate the performance of Fibermart outdoor armored fiber optic cables under extreme temperatures, we conducted detailed tests.

 

High Temperature Testing:

 

• Test Environment: The cable was placed in a constant temperature chamber set at 70°C for a month to simulate high-temperature conditions.
• Results: The test results showed no softening or melting of the outer sheath material, and the transmission loss of the fiber core remained within 0.1dB, proving that the cable maintains excellent transmission performance under high temperatures.

 

 

Low Temperature Testing:

 

• Test Environment: The cable was placed in a freezer at -40°C for a month to simulate polar conditions.
• Results: The test results showed that the cable maintained good flexibility in low temperatures, with no breakage of the fiber core, and transmission performance loss remained within 0.2dB, indicating that it can function normally in extremely cold conditions.

 

2. Humidity and Salt Fog Testing

Humid and salty environments pose high demands on the waterproof and anti-corrosion properties of cables.

 

Humidity Testing:

 

• Test Environment: The cable was placed in a constant humidity chamber with 95% humidity for three months.
• Results: After the humidity test, the waterproof layer of the cable effectively prevented moisture infiltration, and the transmission performance of the fiber core was not affected, with transmission loss remaining within 0.15dB.

 

Salt Fog Testing:

 

• Test Environment: The cable was placed in a salt fog chamber to simulate the corrosive environment of coastal areas for three months.
• Results: The test results showed no significant corrosion spots on the cable surface, with the armored layer and sheath material displaying excellent anti-corrosion capabilities, and transmission performance remained stable.

 

II. Compression and Tensile Strength

In practical applications, fiber optic cables often need to withstand various mechanical stresses such as heavy loads and stretching.

 

1. Mechanical Stress Testing

 

Heavy Load Compression Testing:

 

• Test Method: The cable was repeatedly compressed under a heavy load of 500N.
• Results: The test results showed no significant damage to the armored layer and outer sheath, with the internal fiber core intact and transmission performance unaffected.

 

 

Tensile Testing:

 

• Test Method: Tension was applied to both ends of the cable, with a maximum tension of 800N.
• Results: The cable did not break under tension, and the fiber core maintained stable transmission performance, with transmission loss changes not exceeding 0.2dB.

 

2. Data Analysis

Data analysis of the cable performance under different pressures and tensions showed its superior performance in high-pressure and high-stress environments. For example, under 1000N pressure, the cable's transmission loss increased by only 0.2dB, and under 800N tension, the transmission loss increased by less than 0.3dB, fully proving its reliability in high-stress environments.

 

III. Waterproof Performance

Waterproof performance is an important indicator of the reliability of outdoor armored fiber optic cables in humid environments.

 

1. Waterproof Design

 

Structural Features:

 

• The Fibermart outdoor armored fiber optic cable adopts a double-sheath design, with the inner layer sealed with waterproof glue and the outer layer made of high-density polyethylene (HDPE) sheath.
• Waterproof sealing technology is used at joints and connection points to further enhance waterproof performance.

 

 

2. Test Experiment

 

Experimental Setup:

 

• The Fibermart cable was submerged in 1 meter of water for a week, simulating a high-pressure water environment.
• The results showed no signs of water infiltration inside the cable, and transmission performance was not affected, with transmission loss remaining within 0.1dB, proving its excellent waterproof capability.

 

IV. Corrosion Resistance

Fibermart fiber optic cables exhibit strong corrosion resistance in corrosive environments.

 

1. Material Selection

 

Armored Layer Material:

Stainless steel and coated steel are used, providing high corrosion resistance and stability in acidic, alkaline, and salt fog environments.

 

Sheath Material:

Polyethylene material with strong corrosion resistance is used to effectively prevent chemical corrosion.

 

2. Corrosion Testing

 

Experimental Setup:

 

• The Fibermart cable was exposed to simulated acid rain and industrial waste gas environments for three months.
• The results showed no significant corrosion spots on the cable surface, with the internal fiber transmission performance unaffected, maintaining transmission loss within 0.2dB, proving its high reliability in corrosive environments.

 

 

V. UV Resistance

UV radiation can cause aging of cable materials, affecting their service life and performance.

 

1. UV Protection Measures

 

Material Characteristics:

The outer sheath of the cable is made of UV-resistant materials such as polyvinyl chloride (PVC) and fluoropolymers, with UV inhibitors added to enhance anti-aging performance.

 

2. Long-Term Exposure Experiment

 

Experimental Setup:

 

• The cable was exposed to direct sunlight for six months, simulating long-term UV exposure.
• The results showed no significant aging of the sheath material, with the fiber core maintaining stable transmission performance, and transmission loss changes not exceeding 0.1dB, proving its applicability in UV environments.

 

VI. Temperature Tolerance Range

Different temperature environments have varying impacts on the performance of Fibermart cables.

 

1. High Temperature Environment

 

Application Example:

 

• In a desert fiber optic communication project, the cable was exposed to temperatures up to 60°C, running continuously for six months.
• The results showed no damage from thermal expansion and contraction, with stable transmission performance, meeting the demands of high-temperature environments.

 

 

2. Low Temperature Environment

 

Application Example:

 

• In a polar research station communication network, the cable was used in -50°C extreme cold conditions.
• The results showed the cable maintained good flexibility in low temperatures, with no breakage of the fiber core, ensuring normal operation in extremely cold environments.
