How can you maintain fiber optic networks during extreme weather?

Maintaining Fiber Optic Networks during extreme weather conditions require careful planning, proactive measures, and prompt responses to potential issues. Here are some strategies. 1. Preventive Maintenance. 2. Weather Proofing. 3. Power Back Up. 4. Remote Monitoring. 5. Emergency Response Plans. 6. Proactive Measures. 7. Training and Education. 8. Collaboration with Authorities. 9. Post Event Assessment. 10. Continuous Improvement. By following these best practices, you can enhance the resilience of your fiber optic network and minimize the impact of extreme weather events on its performance and reliability.

Maintaining fiber optic connections during extreme weather requires a proactive approach that safeguards both the cable, especially in adopting strategic cable placement. Route cables underground whenever possible to minimize exposure to wind, ice, and other airborne hazards. If aerial installation is necessary, choose high-clearance routes away from trees and potential falling objects. With that, we can significantly enhance the resilience of our fiber optic network and ensure reliable communication even during the most challenging weather conditions.

Expect the unexpected. If the area has a potential to be affected by tornados, plan for materials to restore quickly. This could be OSP inventory for aerial deployments, electronics (or passive) cabinets, and the manpower available to complete restoration. In coastal areas, take into consideration the potential for hurricane winds or storm surges. Look for opportunities to move equipment further away from the coastline, and higher elevations if at all possible. Expect lengthy power outages after a major storm. Having well maintained batteries, generators, and prepared team will make the difference between networks that are functional after a storm and ones that are not.

One of Your best opportunities to protect and maintain fiber networks is to keep your facilities UG as much as possible. The second and probably most important is full redundancy.

In my experience, while I was working as an O&M Engineer in India, prior to the onset of the monsoon season, we had a Monsoon Preventive Maintenance Plan in which risks and criticality were assessed and prioritized accordingly.

Short circuit and corrission does not relates to fiber optic transmission, though it's very important to shield the optic cable properly to avoid any damage due to extreme weather conditions. Loose FOC should b installed underneath to avoid impact of temperature changes .

One of the most important steps to maintain your fiber optic network during extreme weather is to protect the cables from physical damage, moisture, and temperature fluctuations. You should use durable and weather-resistant materials such as armored or aerial cables, conduit pipes, splice closures, and junction boxes to shield the fibers from external forces and elements. You should also seal any gaps, cracks, or holes where water or dust can enter and cause corrosion, short circuits, or signal loss. Additionally, you should avoid bending, twisting, or stretching the cables beyond their limits, and use proper installation and handling techniques to prevent stress or strain.

Extreme weather, talking particularly impact and remedial measures against higher temperatures, dust and water/moistur are must. In my opinion, it is wise to bury fiber optics encompassing through composite conduit (which are not ingredients in nature) at a depth of atleat 3 ft or 1 meter (it will absorb impact of varying temperatures in the environment). Furthermore, all the junction points should be vigilantly sealed and moisture/water proofed as the moisture or water on these connections points can terminate information connectivity.

Preservar a seguran?a dos cabos é essencial para a manuten??o da infraestrutura de fibra óptica, especialmente em condi??es climáticas extremas. Ao aplicar medidas de prote??o eficazes, garantimos a integridade e a confiabilidade da rede, mesmo diante de eventos climáticos adversos. Isso é crucial para assegurar a continuidade dos servi?os de comunica??o, permitindo que empresas, institui??es e comunidades permane?am conectadas e operacionais, mesmo em circunstancias desafiadoras. Portanto, investir na prote??o adequada dos cabos n?o apenas resguarda o investimento em infraestrutura, mas também fortalece a resiliência e a confiabilidade dos servi?os essenciais de comunica??o.

Inspection is the best practise for uptime in extreme weather conditions. As I have seen in my past experience, we used to inspect the fiber path/ splice closures / conduit / armoured or aerial cable. Health check pre & post after activities on the equipments. Lastly not the least backup power source functional status.

Maintaining your fiber optic network during extreme weather necessitates a crucial step: regularly inspecting the supporting equipment. This includes optical transmitters, receivers, amplifiers, switches, routers, and servers. Regularly assess the performance, functionality, and overall condition of these devices. Promptly replace or repair any faulty or damaged components. Ensure the equipment has proper ventilation, cooling, and heating systems to prevent issues like overheating or freezing. Test backup power sources, such as generators, batteries, or solar panels, to guarantee their operational readiness and adequacy in case of a power outage. This proactive equipment inspection ensures the reliability and resilience of your network.

Regular checking of Cable Condition, Equipment on site, is essential to a network. Because sometimes, even with the most advance NMS, it may only give an alarm when an equipment failed already, but an actual inspection, we can already see if an equipment needs replacement before any incident even occurs.

En la gestión y mantenimiento de redes de fibra óptica, la supervisión desempe?a un papel crítico. Es fundamental realizar una supervisión constante y precisa de los parámetros de la red para asegurar su estabilidad y rendimiento, sobre todo en momentos de condiciones climáticas adversas. La supervisión activa nos permite detectar de manera temprana cualquier anomalía o deterioro en el sistema, lo que a su vez nos habilita para tomar medidas correctivas de manera oportuna y garantizar así una conectividad confiable y continua para los usuarios.

Cable ageing should also be checked if the cable is nearing its EOL. It should be flagged as aged cable, and special monitoring is required because fiber brittleness can lead to unforeseen cuts. More importantly, aged cable should be replaced asap.

Through true monitoring & by taking effective proactive measures on expected probabilities to overcome towards desired healthy performance!

Constant and remote monitoring of your fiber optic network is a third essential step to maintain its resilience during extreme weather. Utilize software tools, sensors, and alarms that promptly alert you to any issues or anomalies. Measure key network parameters, including signal strength, bandwidth, latency, jitter, and error rate, comparing them with baseline or expected values. Identify sources and locations of problems like fiber breaks, cuts, or bends, and promptly isolate or reroute affected segments to minimize service disruption or degradation. This proactive monitoring strategy ensures quick response and mitigation of issues, enhancing the overall performance and reliability of your fiber optic network in challenging weather.

In responding to emergencies during extreme weather, it's crucial to act swiftly and effectively, utilizing prepared resources and procedures. Maintain a team of trained technicians capable of safely accessing sites for necessary repairs or replacements. Ensure the availability of a backup or alternative network to offer temporary or partial service until the main network is restored. Communicate transparently with customers, partners, and stakeholders, providing regular updates on the status and progress of network recovery.

Lamentablemente las empresas ven la capacitación de su personal como un gasto y un retraso en las actividades diarias, sin embargo, un grupo de trabajo con la capacitación adecuada puede encontrar y corregir una falla en el cableado de fibra óptica un 30% más rápido en tiempo y con un resultado un 45% superior en efectividad y calidad respecto a un grupo con conocimiento empírico exclusivamente

RAMS (Reliability, Availability, Maintainability, Safety) rules and calculations apply, i.e. it depends on many factors, e.g. how and where these these fibers are installed or extended, whether it is underground, under the ocean, physical protection. Relation to other disciplines is essential because if they are installed in conduits underground, one of the biggest issues would be water leaks leading to freezing and thawing as that would put so much strain on the fiber changing the properties permanently leading to significant signal losses or even communication failure.

Based on my experience, fiber cables can't get to their EOL because of accident / human intervention. 1. Poles used can't support anymore additional weight from cable - (Solution always have an inspection with the Electric Corporation to check if poles can still be used for Cable Mounting) 2. Fiber Cables are cut by Government officials - (Always get a certificate and permits to avoid this kind of issues) 3. The fiber main link must have at least one backup, either a radio link or another fiber link, but it must be on another route to prevent both the main and backup links from experiencing downtime if an accident occurs.

In addition to the previously mentioned strategies, consider the following factors when maintaining fiber optic networks during extreme weather: 1. Route Diversity 2. Environmental Monitoring 3. Regular Inspections 4. Severe Weather Preparedness 5. Backup Communication Channels 6. Community Engagement 7. Supplier and Contractor Relationships

Having Route diversity to harden your network is key. Implementing SD WAN along with a co-primary Fixed Wireless connection will help with business continuity.
