What's my frost depth line for OSP copper and fiber cable?

In one of our previous blog post we talked about the burial depth of your copper and fiber cable, how copper cable should be at a minimum of 24 inches and how fiber should be at a minimum of 1 meter. Let's dig more into the attached term "Minimum" and how the frost line in your area will change that.

The frost line is the depth to which water in the soil will freeze in the winter. You should know this before you lay your cable down, water expands as it freezes and will cause damage to your communications investment.

The frost line will vary depending on your location and can range from 3 to 6 feet. An easy way to determine your line is by examining a frost line map.



National frost depth maps are only a reference, you should check with your local building inspector for a more accurate measurement for your area.



I hope this has shed some more light into the "Minimum" term of your burial cable depth. Measure twice cut once!
