Introduction
Passive optical network is a new type of technology means applying in home or business to connect multiple users with one fiber connection. The outdoor optical cable also has the highest strength, which is Si—-inertial intensity of fiber.
The service life ts of outdoor optical cables in the use environment is related to the stress σ it bears and the inertial strength si of the optical fiber as follows: lgts=-nlgσ+1gB+(n-2)lgsi. The last two terms in the above formula are constants. Therefore, when the stress σ is constant, the service life ts of the optical fiber is only related to the value of the optical fiber fatigue parameter n. The larger the service life n of the outdoor optical cable, the longer ts.
For the service life of outdoor optical cables, there are two countermeasures: 1. Increasing the static fatigue parameter n to increase the service life of outdoor optical cable; Method 2: If the fatigue parameter n of an optical fiber is fixed, then its service life ts only depends on the stress σ it withstands. Therefore, the less stress that must be borne by an optical fiber is a way to ensure an outdoor drop cable service life.
Protective Material and Type Enclosures
Cable jackets and coatings designed for outdoor environments can help shield cables from the elements. Buried cables are installed in protective conduits or trenches, so that they will neither be disturbed nor damaged by weather and animals. Cable glands and seals are also a must-have to prevent moisture or other contaminants from entering the cable - which would otherwise result in corrosion problems and signal loss.
Strategies for environmental protection
Cable Type: You need to take consideration weather/ environmental conditions when selecting the type of cable. Ensuring high UV resistance, temperature extremes and moisture are avoided on cables is critical. Erosion control practices protect the structural integrity of protection installations and reduce soil sliding influence, thus avoiding cable exposure with possible direct damage effecting long-term service life.
Cable Protection Technologies Refinement
In addition, sensors or monitoring systems can measure things like cable stress and environmental changes so preventative maintenance may begin. Maintenance applications in hard to reach areas can also benefit from robotics and drones, improving the efficiency of cable protection operations. Cable failures can be predicted even before they happen, providing the timely maintenance needed to minimize downtime as well as its associated costs through real-time monitoring and predictive analytic.
Documentation and Cable Management
Documentation around which cables were used where and when they got installed is a MUST in order to stay efficient with your cable management. Keeping records of maintenance activities and maintenance or replacements is an important part in how to record vehicle expenses for the benefit of providing a history, which can be useful in future decisions. This way you will to get accurate and easily available cable management plans because it is really essential that all information must be up-to-date.
Training and Awareness
Above all, the education of staff when it comes to cable handling and maintenance is key. We regularly train other cable maintenance personnel on the latest outdoor fiber optical cables treatment techniques. Educating employees about the hazards of outdoor fiber optic cables empowers a culture or caring and quality assurance.
Conclusion
For the service life of outdoor optical cables, there are two countermeasures: 1. Increasing the static fatigue parameter n to increase the service life of outdoor optical cable; Method 2: If the fatigue parameter n of an optical fiber is fixed, then its service life ts only depends on the stress σ it withstands. Therefore, the less stress that must be borne by an optical fiber is a way to ensure an outdoor drop cable service life.
moisture and water resistance must be noticed throughout the optical cable manufacturing process, residual stress should be decreased since each raw material utilized for manufacture of cables has over 30 year service life and high stability of its physical chemical properties. This is because the life of optical cable can only be prolonged if it strictly control each process in various manufacturing processes.
