I've got to replace a section of 2 fiber cable that was apparently damaged by water freezing in the raceway near where the conduit exits the ground. The fiber is of loose tube construction and is designed for direct burial or underground duct installation. The tube that contained the fibers was crushed and the fibers broken. There is no evidence of damage to the above grade part of the conduit run. The conduit was full of water up to about 2' above grade before I removed the cable, so I don't think there is ice damage to the conduit below grade. I have to install a splice box about 200' feet away and install new fiber in the existing underground conduit. I'm looking for suggestions on how to avoid this same type of damage to the new fiber. I've been thinking about digging down to the 90s at each end of conduit and putting in some washed gravel for a drain bed and drilling some drain holes in the conduit.
