Outdoor fiber optic cable OS2 DAC for direct burial, orange SM 4J 9/125 G652D Fca PE ALANTEC FOK-D4J-SM

Fiber optic cable for direct burial – reliability and durability

This orange OS2 fiber optic cable, designed for direct burial, is a robust solution for extensive telecommunications networks and beyond. Manufactured by ALANTEC, it is characterized by increased strength and resistance to mechanical damage, making it an ideal choice for installations in areas exposed to loads. This cable is particularly useful in backbone networks, CATV, WAN, FTTx, and campus systems.

The key to its durability is its construction – a glass fiber sheath and two FRP (Fiber Reinforced Polymer) rods embedded in the outer jacket provide high resistance to crushing. The internal tube filled with hydrophobic gel protects the optical fibers from moisture, and an additional layer of glass fibers acts as an anti-rodent barrier. The PE coating resistant to UV radiation, acids, alcohols, and salt solutions guarantees long-term operation even in harsh weather conditions. Length markings every meter facilitate precise cutting and installation.

Parameters and application

The cable uses 9/125 μm single-mode optical fibers of type G.652D OS2, providing high-quality data transmission over long distances with minimal dispersion. Four fibers inside the cable enable redundancy or additional connections. The orange color makes it easier to identify the cable during installation and maintenance. Fire class Fca means that the cable meets fire safety standards for outdoor installations.

The cable construction with a loose tube facilitates the processing and splicing of optical fibers, which translates into saving time and costs during installation. This is especially important for professional installers who value convenience and efficiency. In addition, the cable is suitable for burial in the ground after applying appropriate insulation and protection against moisture.

Advantages for the installer and end user

• Mechanical strength: Resistance to crushing thanks to the glass fiber sheath and FRP rods ensures long-term reliability even in harsh conditions.
• Moisture protection: Hydrophobic gel filling the tube protects the fibers from dampness, preventing signal degradation.
• Rodent protection: A layer of glass fibers provides an effective barrier against rodents, protecting the cable from damage.
• Weather resistance: The PE coating resistant to UV radiation and chemical substances ensures the durability of the cable outdoors.
• High transmission quality: G.652D OS2 single-mode fibers guarantee stable and fast data transmission over long distances.
• Easy installation: The construction with a loose tube facilitates the processing and splicing of optical fibers.
• Identification: The orange color makes it easier to identify the cable during assembly and subsequent network maintenance.
