GYFTY-48 Fiber Optic Cable – High-Density, Future-Ready Connectivity for Demanding Networks

The GYFTY-48 fiber optic cable is a high-capacity, outdoor-optimized solution engineered to meet the growing demands of modern telecommunication and data networks. With 48 cores of single-mode or multimode fibers, this cable delivers exceptional bandwidth and scalability, making it ideal for backbone networks, metro expansions, and large-scale FTTH deployments.

Designed for harsh environments, the GYFTY-48 features an advanced loose tube structure filled with water-blocking gel, ensuring superior protection against moisture, temperature extremes, and mechanical stress. Its dual-layer reinforcement—corrosion-resistant steel wire and FRP (fiberglass reinforced plastic) central strength member—provides unmatched tensile strength and crush resistance, while the high-density polyethylene (HDPE) sheath defends against UV radiation, chemicals, and rodent damage.

Key Advantages:
- 48-core high-density design for efficient, space-saving installations
- Optimized bend performance with G.657.A1-compliant fibers for tight routing
- Low insertion loss & superior signal integrity for long-haul and high-speed applications
- Versatile deployment options—suitable for aerial, direct burial, and duct installations
- Strict compliance with IEC, ITU-T, and RoHS standards

Built for reliability in the most challenging conditions, the GYFTY-48 fiber optic cable ensures long-term performance, reduced maintenance, and seamless upgrades for next-generation networks.
Future-proof your infrastructure with GYFTY-48 – Where capacity meets resilience.
