Ribbon 288-core optical cable

A 288-core ribbon optical cable is a high-density fiber optic cable designed for efficient mass fusion splicing and high-capacity network deployments.

Overview

A 288-core ribbon optical cable consists of multiple optical fibers bundled in flat ribbon formats, typically with 12 fibers per ribbon, allowing for 24 ribbons per cable to reach 288 fibers. These cables are designed for high-density applications such as data centers, metro networks, and 5G backbones, where space efficiency and rapid deployment are critical .

Cable Structure

• Ribbonized Fibers: Fibers are grouped into ribbons that are flexible and finger-peelable, enabling easy mass fusion splicing and termination with 12-fiber MPO connectors .
• Subunits: Each ribbon or group of ribbons is housed in a sub-unit tube, which simplifies handling, routing, and installation .
• Fiber Types: Commonly uses singlemode OS2 fibers, available in 200 µm or 250 µm outer diameter, with bend-insensitive designs to reduce signal loss in tight bends .
• Strength Members: Dielectric or steel strength members are included to provide tensile strength, anti-buckling protection, and durability in both indoor and outdoor environments .
• Jacket: Indoor cables often feature Low Smoke Zero Halogen (LSZH) jackets, while outdoor variants may include armored or water-blocking jackets for duct, aerial, or direct-buried installations .

Installation and Handling

• Mass Fusion Splicing: The ribbon design allows simultaneous splicing of 12 fibers, significantly reducing installation time in high-fiber-count deployments .
• Finger-Peelable Subunits: Subunits can be separated without tools, allowing direct routing into hardware without additional furcation .
• Compact Design: Flexible ribbons and optimized subunit stacking enable high fiber density while maintaining manageable cable diameter and bend radius .

Applications

• Data Centers: High-density horizontal and backbone cabling for servers and switches.
• Telecom Networks: Metro and long-haul networks requiring high fiber counts.
• 5G and Small Cell Deployments: Supports dense fiber requirements for cellular backhaul .

Key Advantages

• High Fiber Density: 288 fibers in a single cable reduce conduit and pathway requirements.
• Efficient Splicing: Ribbonized fibers allow mass fusion splicing, saving time and labor.
• Flexible and Durable: Bend-insensitive fibers and robust jackets ensure reliability in tight spaces and harsh environments.
• Scalable: Subunit design allows easy expansion and integration into larger fiber networks . In summary, 288-core ribbon optical cables are engineered for high-capacity, high-density network environments, combining efficient fiber management, rapid installation, and robust performance for both indoor and outdoor applications.
