The service life of optical fiber bushing

The service life of fiber optic bushing is not a fixed value, but is affected by a variety of factors, including the external environment, material quality, installation method and maintenance. The following is a detailed analysis of the service life of the fiber sleeve:

First, the factors affecting the service life

External environment:

Fiber sleeve is often exposed to outdoor environment, high temperature, cold, wet, sun and rain will directly affect its service life. Especially in a humid environment, it is easy to lead to corrosion and rust, which accelerates the aging process.

Water molecules and water vapor in the atmospheric environment will also etch the surface of the fiber, gradually reducing the mechanical strength of the fiber, and eventually leading to fracture.

Material quality:

The material quality of fiber bushing directly affects its service life. The high-quality cast iron material is not only anticorrosive and durable, but also has high strength and long service life.

New optical fiber bushing materials, such as the use of more advanced optical fiber materials and sheath materials, can improve the anti-aging, corrosion resistance and mechanical damage resistance of the optical cable, thereby extending the service life.

Installation method:

A good installation method guarantees the service life of optical fiber bushing. During installation, ensure that the casing is tightly fitted to the cable to avoid wear and friction.

The long-term effect of residual stress during unreasonable laying of optical cable will also adversely affect the service life of optical fiber bushing.

Maintenance:

Regular inspection of the condition of the fiber sleeve, timely detection of problems and repair or replacement, can maintain its protective function and extend the service life.

Frequent removal of dirt from the casing, especially after prolonged exposure to the environment, can reduce the risk of corrosion and rust.

Second, the specific service life range

Due to many factors, it is difficult to give a definite value of the specific service life of optical fiber bushing. However, in general, in a more stable and ideal indoor environment (such as a place with moderate temperature, low humidity, no obvious mechanical stress and chemical corrosion), the service life of optical fiber bushing can reach a long period of time, such as 15-20 years or even longer. In the case of relatively complex and harsh outdoor environment, the service life will be shortened accordingly, but the appropriate protective measures (such as the use of protective casing, strengthening fixing, etc.) can extend its life.

Third, the method of extending the service life

Choose high-quality materials: When choosing optical fiber bushing, priority should be given to products with excellent materials, corrosion resistance and durability, and high strength.

Reasonable installation: During the installation process, ensure that the casing and the cable are tightly fitted to avoid unnecessary stress and friction.

Strengthen maintenance: Check the casing condition regularly, remove dirt in time and carry out necessary repair or replacement work.

Protective measures: When used in an outdoor environment, protective measures such as protective sleeves can be considered to reduce the impact of the external environment on the optical fiber sleeve.

In summary, the service life of optical fiber bushing is affected by many factors, but by selecting high-quality materials, reasonable installation, strengthening maintenance and taking appropriate protective measures, it can effectively extend its service life and ensure the stability and reliability of optical fiber communication system.
