72-core single-mode optical cable

A 72-core single-mode optical cable is designed for high-capacity data transmission, available in both indoor/outdoor and armored direct-buried configurations, supporting OS2 fiber standards.

Overview

Single-mode 72-core optical cables are used for long-distance, high-speed data transmission in telecommunications, data centers, and enterprise networks. They consist of 72 individual optical fibers, typically with OS2 single-mode fibers, which allow low attenuation and high bandwidth over long distances .

Construction Types

1. Loose Tube Outdoor Cables
   • Fibers are housed in gel-filled PBT loose tubes for protection against moisture.
   • Central strength member made of phosphatized steel wire or aramid yarn provides tensile strength.
   • Outer sheath options include PE or LSZH jackets, sometimes with steel tape or aluminum tape armor for rodent and mechanical protection.
   • Suitable for direct burial or duct installation in harsh environments .
2. Distribution Cables for Indoor/Outdoor Use
   • Tight-buffered fibers with colored jackets for easy identification.
   • Aramid yarn strength members and PVC outer jackets provide flexibility and protection.
   • Small bend radius allows installation in confined spaces and fast terminations .
3. MTP/MPO Connectorized Cables
   • 72 fibers can be arranged as six 12-fiber MTP connectors or three 24-fiber MTP connectors.
   • Dual-jacket design with protective yarn increases durability and reduces insertion loss.
   • Commonly used for 100G links in data centers, supporting CPAK, CFP2, or CXP transceivers .

Key Features

• High mechanical strength: Crush and tensile resistance for outdoor deployment.
• Environmental protection: Water-blocking compounds, armored layers, and UV-resistant jackets.
• Non-conductive: Immune to electromagnetic interference, safe for installation near power lines.
• Flexible deployment: Suitable for indoor, outdoor, duct, or direct-buried applications.
• Fast installation: Tight-buffered or MTP connectorized designs simplify network setup .

Applications

• Long-haul telecommunications and metro networks.
• Data center backbone connections for high-speed 100G or 400G links.
• Enterprise campus networks requiring high fiber density.
• Harsh outdoor environments where armored protection is necessary. In summary, a 72-core single-mode optical cable provides a high-density, reliable solution for long-distance and high-speed fiber optic networks, with multiple construction options to suit indoor, outdoor, and direct-buried installations .
