Protect your broadband network: how to prepare for a natural disaster


broadband-network-natural-disaster-blog.jpgNatural disasters such as hurricanes, tornadoes, earthquakes and ice storms will always be the enemy of cable and internet service providers, but there are things you can do to ease the burden of long-term issues from a storm or earthquake.

We’ve seen the challenges first-hand and have tips to help make your broadband network post-disaster restoration as flawless as possible.

Preparing inventory for a storm

In addition to a service provider’s own operational procedures, making sure you have the most-needed materials before the event will save time, money and subscriber aggravation. Choosing which inventory to stock is dependent upon region and the type of natural disaster, but the most common products service providers need after a hurricane, tornado, earthquake or ice storm hits are hardline jumpers, patch kits, aerial cable, underground cable, hardware and outdoor connectors.

  1. Flexible Hardline jumpers - These can be used temporarily when a technician needs to bypass equipment (taps, amps) that requires maintenance or replacement.
  2. Patch kits - Instead of replacing all aerial cable if there was a clean break – such as if a tree fell and broke a line – a patch kit could be used to fix the cable instead. This only works if the cable wasn’t compromised by water or snow.
  3. Aerial cable - This is one of the most widely needed parts after damage because it’s vulnerable to the elements. The minimum break strength requirements for aerial cable is 170 to 340 lbs. – depending on the cable size – which is not enough to withstand fallen trees or heavy ice loads.
  4. Underground cable - Any cable that runs underground is most prone to issues if a storm causes flooding. It’s important to replace all cable that could be impacted by a water leak. Specifically, orange cable is often used as temporary drops to help get service running quickly. Orange cable is easy to locate as technicians return with a more permanent solution.
  5. Hardware - Aerial and house hardware all tend to receive major damage during a wind storm, as hardware is only rated to the same strengths as the aerial cable itself. All hardware, including drop clamps, p hooks, span clamps and ground blocks, should be stocked for quick replacement.
  6. Outdoor connectors - Rain and flooding can cause water to enter a connector, which exposes the components to corrosion. All connectors damaged by water need to be replaced – preferably with water-tight connectors to help avoid this issue in the future.

Post-storm restoration efforts

Restoring cable or internet service after a disruption due to a major natural disaster can be a daunting task. Technicians may not know where to start or may rush through a repair without fixing all of the problems, such as a flooded cable or tap.

One of the most common problems we see during post-storm repair is technicians replacing connectors, but not any of the other components of a drop network, such as cable. It’s important to replace all aerial and underground cable at the first sign of water ingress because water can corrode the components inside the jacket and make the cable unusable. Although replacing the connector alone may get a customer up and running, the cable could still have water in it – leading to future problems.

In one particular scenario we witnessed, several telephone poles fell into flooded water and were “fixed” by standing them upright again. However, they didn’t change any of the pieces of the drop – taps, cable or connectors – which turned out to be flooded with water. Once water gets in the system, it’s not going away unless fully replaced. Water can travel hundreds of feet down a cable and if it’s salt water, corrosion can happen at an even-quicker speed than usual.

While replacing parts that were damaged by a storm, we suggest adding water-tight connectors to all outdoor connections. Connectors with a water-tight seal can help protect from water leakage in the future, but only if the rest of the drop hasn’t been compromised by water already. It’s important to check the entire system for water ingress and replace any parts that aren’t in working order.

If there are water issues lingering after the post-storm restoration, the service provider will likely get calls from subscribers about poor network performance and will need to send another technician to troubleshoot and replace the damaged parts.

All natural disasters are going to pose different issues for service providers, but the one thing that’s certain is how the company prepares for it. In the case of hurricanes, the storms are predicted enough in advance to stock inventory that will be most needed during restoration. Once a natural disaster hits and restoration work is fully underway, it’s even more important for technicians to properly replace all parts that have been damaged to avoid a service call in the near future.
