Product Introduction
657. The A2 type anti-bending single-mode fiber offers two specifications, with diameters of 200 micrometers and 242 micrometers, and is protected using a special high-performance acrylic resin composite material. This fiber maintains excellent bending loss characteristics even under reduced dimensions. Smallsized fibers can significantly conserve pipeline resources, enhance cable laying capabilities, and improve construction efficiency, making them the ideal choice for building urban regional networks and access network broadband infrastructure in a “environmentally friendly and energy-efficient society.
Performance highlights
● Special composite coating material, good bending loss characteristics
● Less bending loss.
● Smaller size optical fiber can be selected, and the designed cross-sectional area of optical cable is reduced by more than 30%,which improves the laying density of optical cable and effectively saves pipeline resources.
Application scenario
● High-density metropolitan area network and access network in narrow environment
● Air-blown micro-cable
● FTTx
