This specification covers optical armored cables with 2 or 4 fibers. The LDA tactical cable is equipped
with stainless steel tube and stainless steel wires for excellent protection of fibers against rodents and
mechanical damaging. Outer jacket is made of polyamide. The Stainless Steel Tubes cable can be
applied in several market segments / cable constructions :
- Aerial optical cables like OPGW (Optical Ground Wire), OPPC (Optical Phase Conductor)
- Units integrated in hybrid cable constructions for DTS systems
- Underground optical cables – uni-tube constructions - for direct buried, duct and indoor installations
- Submarine optical cables
This specific design is for mobile deployable application in harsh environment and will maintain function
in fire. The Polyamide outer sheath is highly resistant against chemicals.
Cable design:
- Fibers: specifications of G652D fiber
- Steel Tube: consists of laser welded hermetically sealed stainless steel
- Tube Filling: the tube is filled with water repellent filling compound.
- Armor: one layer of stainless steel wires
- Outer sheath: Polyamide (Black)
- Army and air force tactical networks
- Oil research, heavy industry
- Broadcasting
- Connection to and of moving objects
