Blowing
Applied in tubes, ducts, trays, blocks, tunnels, collecting channels, with no risk of rodent attacks. Also applied for aerial installation between supports and buildings on external strength members or using the winding method.
Ducting
Applied in ducts, trays, blocks, tunnels, collecting channels, with a risk of rodent attacks.
Direct Buried
Applied in harsh environments with potential mechanical impact: in all ground types, swamps and harsh rivers.
Submarine
Applied in sea areas (coastal shelf and deep-sea), on navigable rivers, in lakes and water storage basins, in harsh environments, in bogs and unnavigable rivers.
Figure 8
Applied for aerial installations: on power lines, lamp posts, between buildings and constructions. Suitable for aerial installation on transmission equipment and power facilities in dielectric package.
Aerial
Applied for aerial installation on distribution and high voltage power lines, as well as railway catenary.
Indoor
Applied inside buildings (including vertical runs), in trays, channels, on outer sides of buildings, as well as in duct, in tubes and blocks. Suitable for blowing-in into protecting polyethylene tubes.
Drop
Applied for aerial installation on transmission towers, lamp posts, between buildings and constructions.
OPGW/Ground Wire
Applied in the construction of fiber-optic link on overhead transmission lines of 35 kV and more.
Fire Rated
Used for stationary installation when the optical fiber needs extra protection from mechanical damages.
Specialty Cable
For fiber optic monitoring systems.
