GJYXFCH-2B6 2Cores G657A1 FTTH Outdoor Drop Cable Specifications Datasheet

The design of the GJYXFCH-2B6 drop cable is both innovative and functional. At its core, the optical fiber unit is strategically positioned at the center, surrounded by two 0.5mm parallel Fiber Reinforced Plastics (FRP) that enhance the cable's durability. In addition, a traditional strength member made of 7*0.33 mm steel wire is incorporated to ensure the cable's tensile strength. Finally, the cable is enveloped in a black or color Low Smoke Zero Halogen (LSZH) sheath, ensuring safety and performance in outdoor environments.

Characteristics

The GJYXFCH-2B6 FTTH cable boasts several key characteristics that make it an exceptional choice for FTTH deployments:

Special Low-Bend-Sensitivity Fiber: It utilizes advanced low-bend-sensitivity fibers, which provide high bandwidth capabilities and excellent transmission properties. This ensures that communication signals remain strong and consistent, even in challenging environments.

Enhanced Crush Resistance: The two parallel strength members significantly contribute to the cable’s resistance to crushing forces, safeguarding the optical fibers during installation and throughout its service life.

Tensile Strength: The inclusion of a steel wire strength member enhances the tensile strength of the fiber drop cable, allowing it to withstand pulling and tension during installation, making it highly reliable for outdoor applications.

Lightweight and Simple Structure: The GJYXFCH-2B6 features a simple yet effective design, resulting in a lightweight cable that is easy to handle and install. This can lead to reduced labor costs and improved installation efficiency.

Novel Flute Design: The innovative flute design allows for easy stripping and splicing of the fibers, simplifying the installation and maintenance processes. This feature is particularly beneficial for technicians in the field.

Safety Features: The LSZH sheath not only provides a durable exterior but also offers low smoke, zero halogen, and flame retardant properties. This is crucial for ensuring safety in the event of a fire, as it minimizes the release of harmful gases.
