INFRALAN U-DQ(ZN)BH OS2 48E (4x12) Eca 5000N LSZH čierny 11,2 mm G657A1 sklenený kábel 54448.1D-E5

Universal fibre optic cable with 48 OS2 single-mode fibres in a robust 4x12 loose tube arrangement, engineered for high tensile strength of 5000 N and bend-insensitive G.657.A1 performance. The black LSZH sheath ensures low smoke and halogen-free safety in fire conditions, meeting Eca CPR classification for indoor and outdoor installations.

Advantages

Bend-insensitive G.657.A1 fibres reduce signal loss in tight bends, while the non-metallic strength member and water-blocking design provide reliable long-term performance. The low smoke zero halogen sheath enhances safety in populated areas, and the 5000 N tensile strength allows for demanding installation pulls.

Suitable for

• Indoor and outdoor backbone cabling
• High-density fibre distribution in data centres
• Installations requiring CPR Eca fire performance
• Environments where low smoke and halogen-free materials are mandatory
