Laying SRV-G tc in the open duct trench is suitable for any terrain and any section of broadband expansion.
In case of rocky or stony subsoil, the trench
bottom must be excavated at least 0.15 m deeper and the excavation must be replaced by a stone-free layer (sand 0-6, with maximum grain size Ø 6 mm). After laying under tension, the cable section must be backfilled with sand up to 10 cm above the bundle peak (see ZTV-TK network 10 / 11 and laying instruction for buriable protective pipes outo of PE-HD.)What is strictly to observe at an open trench?

The farther fibre optics can be blown into a microduct system, the less subsequent underground engineering is necessary. We show you what you need to be aware of.
Cheap and quick variants for the new construction of fibre optic routes outside localities: the cable or duct plough. speedpipe bundles can be ploughed in at the roadside without more ado.
Milling method for speedpipe bundles ground for the new construction of duct routes.
The horizontal directional drilling method offers particular advantages when the conditions make it difficult or impossible to use an open construction method.
