Are you worried that the colder weather might impact your fiber trunk cable? Here’s how you might get affected.

Does Winter Affect Fiber Optic Cables?

Winter is here, and temperatures have started to dip toward freezing! This is the perfect time for you to bundle up at the office, sip on some hot coffee, and tackle your tasks. However, you notice that your fiber optic internet is running a lot slower than before as soon as it starts to snow. Is it a random coincidence, or is it the colder weather that’s impacting the quality of your connection?

While the temperature itself doesn’t affect fiber optic connections, certain by-products of the weather can make an impact. Here’s all you need to know:

Extreme weather

Winters are usually accompanied by blizzards in many areas of Canada and the US. The falling temperatures can cause the snow to accumulate and cause a power outage that can impact your work. However, it has no effect on the cables themselves.

When do cables get affected?

Fiber optic cables face problems when there is water in their ducts. Fiber optic cables are a lot more susceptible to freezing compared to traditional copper cables. If water gets into the housing of your optic cables and freezes, you’ll face severe internet problems. The buildup of ice around the cables can also force them to bend, and depending on the level of bending, the drop in internet performance can range from small disruptions to not getting any signals at all.

Connectivity losses are rather inconvenient for individuals or businesses that rely on fiber optics for their work or daily operations. Your signal strength will probably return to normal when the ice melts, but you might have to wait a couple of days for that to happen.

Why does water penetrate the innerduct?

Condensation and infiltration can cause water to get into the ducts and cause connectivity issues. Imagine a house that’s lying across the road with multiple access points. Water can infiltrate those access points and flow downhill, eventually adding up to potentially hundreds of gallons flowing through the system. If the innerduct is buried deep enough below the frost line, it should be safe from freezing.
