Excellent idea that will run across a ton of hiccups in CATV land. There is no solution that I know of for buried splices and they are everywhere. I suppose if they make a custom fitting for splicing the sheath and leave the core open for feed through but that requires TDRing every cable that won't work and digging up the splice. Pulling it apart and changing the splice at that location.
This is a great idea I just don't see the practicality of it in older CATV plants.
