In many cases field techs entered an innerduct, and water poured out for several minutes.Ĭondensation is another possible culprit, especially at exposed bridge crossings where differences between the ambient temperature and the inside innerduct regularly exist. Where a fiber optic cable is exposed to freezing temps, such as at an exposed bridge crossing, ice can form in the duct. As long as the innerduct is buried below the frost line, no freezing will occur. Water infiltrates these access points and flows downhill, which could lead to hundreds of gallons of water being present in the system. Picture an innerduct as a hose laid out along the road with occasional access points. How does water get into innerducts? It gets in by infiltration and condensation. Signal strength usually returns to normal as the ice melts. Loss of connectivity can be inconvenient to any business that relies on fiber for day-to-day operations. It can lead to fiber optic networks going down unexpectedly. Depending on how extreme the bending is, the signals may not be able to pass through the fiber optic cables at all. If water has the chance to enter into the housing of your cables and freeze, then your overall internet performance will deteriorate. The ice that forms around the fiber optic cables often causes the cables to bend, which affects the signals sent through the cables. There is quite a bit of research that has been done on it, and it appears as though fiber optic cables are affected by cold temperatures whenever water is able to make its way into the ducts housing the cables, and then the water freeze s. Mainly due to freezing cables inside the conduits due to condensation and infiltration.įreezing cables in an innerduct or conduit has been happening as long as cables have been put in to duct s, but fiber optic cable is susceptible to freezing in a way that traditional copper cables are not. However, some of the byproducts of the cold will cause issues with your fiber optic cables. So – What gives? Does the cold weather actually effect the quality of your fiber optic connection, or just a random coincidence? To answer your question – the actual cold temperatures do not affect the quality of your connection. Over the years one of the big challenges associated with fiber optic cables has been the cables poor performance during colder weather. They can also carry more data over further distances – without disruptions! Many advantages come with installing fiber optic cables over traditional copper cables, but that doesn’t mean they are invincible. Fiber optic cables can transmit data much faster than standard copper wires. There are so many advantages that come along with using fiber optic cables over traditional copper ones. The calls are going to start to coming soon, so you need to be ready to troubleshoot and answer their questions! Have you ever noticed when the snow starts to fall, so do your fiber optic internet speeds? You’ve noticed, and so have your customers! Freezing-cold temperatures seem to take a toll on fiber optic cables and cause them to stop working suddenly in some cases. The snow accumulation can lead to outages that can affect your ability to get work done. Winter is here, and with it comes freezing temperatures, snow, sleet and ice storms! The temperature drops, the cold rolls in, and then the snow starts falling at a rapid pace.
