Abstract
The invention relates to a process for introducing an optical cable, in the form of a microcable or minicable (1), in solid ground (17) with the aid of a laying unit (23). The microcable or minicable (1) used for this purpose comprises a homogeneous and pressurized-water-tight tube (8) which has an external diameter of from 2.0 to 10 mm and into which optical waveguides (3) are introduced.
Claims48
A fiber optic cable installation structure comprising:
- a surface defining a channel having a width of about 12 mm or less;
- a cable disposed within the channel, said cable comprising a tube sized to fit within the channel and at least one optical waveguide disposed within said tube;
- and
- a filling material overlying said cable and at least partially filling the channel, said filling material at least partially comprised of material not previously evacuated to form the channel.
