FTTH fiber optic Drop cable 4 Core SM indoor G.657-A1-A2

Fiber Optic Drop Cable access to the use of dish-shaped optical cable (indoor wiring) is the optical communication unit (fiber) in the center, placed on both sides of two parallel non-metallic reinforcement (FRP) or metal reinforcing member, and finally extrusion black or color poly Vinyl chloride (PVC) or LSZH (LSZH, low smoke, halogen-free, flame retardant) jacket.

Characteristic

 

  • Special low-bend-sensitivity fiber provides high bandwidth and excellent communication transmission property;
  • Two parallel FRP strength members ensure good performance of crush resistance to protect the fiber;
  • Single steel wire and FRP as the additional strength member ensures good performance of tensile strength;
  • Simple structure, light weight and high practicability;
  • Novel flute design, easily strip and splice, simplify the installation and maintenance.

Features:

The G.657 standard refers to a specific type of optical fiber designed for telecommunications applications. It encompasses various features tailored to meet the demands of modern communication networks:

  1. Bend Insensitivity: G.657 fibers are characterized by their low sensitivity to bending. This property allows for more flexibility in network design and installation, as the fibers can withstand tighter bends without compromising signal integrity.
  2. High Bandwidth: These fibers offer high bandwidth capabilities, enabling the transmission of large amounts of data over long distances without significant signal degradation.
  3. Compatibility: G.657 fibers are designed to be compatible with existing telecommunications infrastructure, making them suitable for both new installations and upgrades to existing networks.
  4. Reduced Signal Loss: By minimizing signal loss, G.657 fibers ensure efficient transmission of data, resulting in reliable and high-quality communication.
  5. Versatility: These fibers can be used in a variety of applications, including long-haul telecommunications networks, metropolitan area networks (MANs), and local area networks (LANs).
  6. Enhanced Performance: G.657 fibers are engineered to deliver consistent and reliable performance under various environmental conditions, ensuring optimal operation in diverse settings.
