48-core standard optical cable G652

A 48-core G. 652. D optical cable is a single-mode, multi-core fiber cable designed for high-capacity, long-distance transmission with low attenuation and standard dispersion characteristics.

Overview

The 48-core G. 652. D optical cable is a single-mode fiber cable compliant with ITU-T G.

652 standards, optimized for operation around the 1310 nm zero-dispersion wavelength and suitable for both 1310 nm and 1550 nm transmission windows. It is widely used in telecommunications, data centers, and access networks where high fiber counts are required.

Construction

Fiber Type: Single-mode G. 652. D, 9/125 µm core/cladding diameter.

Core Arrangement: Multi loose tube design, typically with gel-filled tubes surrounding a central strength member (often FRP) to provide mechanical stability. Water Protection: Tubes are filled with water-blocking gel, and the cable includes water-blocking yarn and tape to prevent moisture ingress. Outer Jacket: High-Density Polyethylene (HDPE) or PE sheath for environmental protection, suitable for underground or aerial installations.

Strength Members: Central FRP rod and Kevlar yarn for tensile strength and durability.

Performance Characteristics

Attenuation: Low loss, typically around 0. 35 dB/km at 1310 nm and 0. 22 dB/km at 1550 nm, ensuring long-distance signal integrity.

Dispersion: Chromatic dispersion is controlled to maintain signal quality over long distances, with zero-dispersion near 1310 nm. Mode Field Diameter (MFD): Standardized for G. 652.

D fibers to ensure compatibility with splicing and connectors. Mechanical Properties: Designed to withstand installation stresses, wind loads (up to 25 m/s for ADSS variants), and ice loading conditions.

Applications

Telecommunications networks: Backbone and metro networks requiring high fiber counts. Data centers and enterprise networks: High-density fiber deployment for access and distribution.

ADS

S (All-Dielectric Self-Supporting) installations: Suitable for aerial deployment without metallic support, with spans up to 200–500 meters depending on environmental conditions. Underground duct systems: Multi loose tube design allows easy installation and future expansion.

Additional Considerations

Compliance: Meets EU RoHS, REACH, and Persistent Organic Pollutants regulations for environmental safety. Customization: Fiber count, sheath type, and cable structure can be tailored to specific project requirements. Frequency Bands: Supports E-band (1360–1460 nm) and L-band (1565–1625 nm) for extended reach and high-capacity networks.

The 48-core G. 652. D optical cable provides a reliable, high-performance solution for modern fiber optic networks, combining high fiber density, low attenuation, and robust mechanical protection suitable for diverse installation environments.
