MPO branch optical cable

An MPO branch cable (fan-out or breakout cable) splits a high-density MPO/MTP connector into multiple individual connectors, enabling efficient fiber distribution in data centers.

Overview

MPO branch cables are designed to connect a single high-density MPO/MTP connector to multiple sub-connectors such as LC, SC, or MPO, allowing a single trunk cable to distribute signals to multiple devices. This approach maximizes port density, reduces cabinet space usage, and simplifies high-speed interconnections in data centers .

Structure and Fiber Counts

• Single MPO connector end: Typically carries 8, 12, 16, 24, or more fibers.
• Branch end: Splits into multiple connectors (LC, SC, ST, MTRJ, Mini-LC, etc.).
• Fiber types: Available in singlemode (G652D, G657A1/A2) and multimode (OM2, OM3, OM4, 62.5/125) fibers.
• Polarity options: Parallel (A-to-A, B-to-B), crossover (A-to-B, B-to-A), or paired crossover to match network requirements .

Key Features

• High-density connectivity: Consolidates multiple fibers into fewer cables, reducing clutter.
• Pre-terminated and factory-tested: Ensures controlled insertion loss and return loss, supporting plug-and-play deployment.
• Return loss: UPC ≥50dB for short-distance, APC ≥60dB for long-distance, high-bandwidth applications.
• Flexible configurations: Round, square, or custom fan-out cable designs with lengths typically 0.9mm, 2.0mm, or 3.0mm per fiber .
• Compliance: Meets Telcordia GR-1435-CORE, GR-2866-CORE, GR-326-CORE, and RoHS standards.

Applications

• Data centers: Connect high-density servers, switches, and optical modules efficiently.
• Bandwidth splitting: Distributes signals from a single MPO trunk to multiple devices.
• Space optimization: Reduces the number of patch cords and cabinet space usage.
• Compatibility: Works with both new and legacy equipment, supporting high-speed parallel optics like 40G, 100G, 200G, 400G, and 800G applications .

Deployment Considerations

• Connector selection: Choose branch connectors (LC, SC, MPO) based on device port types.
• Polarity management: Ensure correct fiber mapping to maintain signal integrity.
• Cable routing: Round and flexible cables allow 360-degree routing in high-density environments.
• Maintenance: Pre-terminated cables simplify inspection, reduce installation errors, and minimize downtime. MPO branch cables are essential for high-density, high-speed optical networks, providing a scalable and efficient solution for modern data center interconnections while maintaining signal quality and simplifying network management .
