"LOOSE" reinforced optical fibre
For outdoors installation
Data transmission optical fibre cables OM1 OM2 OM3 OS1 (multimode and singlemode)
4 to 24 fibres - outdoors installation - steel reinforcement - PE jacket
62.5/125 OM1, 50/125 OM2, 50/125 OM3, 9/125 OS1
▼ DESCRIPTION
This optical fibre cable features a simple, but very robust construction. The fibres themselves are coated with a 250 micron thick
coloured acrylate which facilitates identification, and are bundled in a single PTB tube with a waterproof sheath, filled with a gel which
provides mechanical and hydroscopic protection. The entire assembly is contained in a corrugated steel tube covered with a black PE
jacket for UV resistance. The cable is further reinforced by two steel strength members for increased traction resistance.
▼ CHARACTERISTICS
• Corrugated steel tube
• Coloured fibres for quick identification
• Double steel strength member for increased traction resistance
• PE jacket
• Black jacket for UV resistance
• 1800 N traction resistance
• Waterproof internal layer
▼ APPLICATION
• Suited for installation in indoors and outdoors cable ducts and overhead supports.
• Suited for use on campus backbones, building backbones, horizontal cabling
• Suited for high density sites and fusion splicing
• Compact structure, suited for installation in limited areas such as duct pipes.
