Nordic ODM Single-Fiber Bidirectional QSFP-DD

The Nordic ODM Single-Fiber Bidirectional QSFP-DD enables high-speed, single-fiber bidirectional connectivity for 100G to 400G networks, optimizing fiber usage and supporting QSFP-DD form factor interoperability.OverviewThe Nordic ODM Single-Fiber Bidirectional (BiDi) QSFP-DD is designed to transmit and receive data over a single optical fiber, effectively doubling fiber capacity without requiring additional cabling. This solution is particularly useful in data center interconnects (DCI), hyperscale Spine-Leaf architectures, and carrier Ethernet networks, where fiber resources are limited or costly . The module is compatible with standard QSFP-DD ports, ensuring plug-and-play interoperability with major switch vendors such as Cisco, Arista, Juniper, and Mellanox/NVIDIA .Key FeaturesSingle-Fiber BiDi Operation: Uses two wavelengths (commonly 1300nm and 1550nm) to enable simultaneous transmit and receive on a single fiber, reducing fiber deployment costs by up to 50% .High-Speed Support: Compatible with 100G, 200G, and 400G QSFP-DD modules, leveraging PAM4 modulation for high data rates .Form Factor Compatibility: Fits standard QSFP-DD cages and connectors, maintaining backward compatibility with QSFP28 and QSFP-DD modules .OEM/ODM Customization: Nordic ODM solutions can be tailored for specific thermal, coding, or vendor lock-in requirements, ensuring optimized performance in dense racks or multi-vendor environments .Passive Adaptor Technology: Many BiDi solutions, like RAD's patented miniature passive adaptor, require no active electronics, simplifying deployment and reducing power consumption .ApplicationsData Center Interconnects (DCI): Efficiently connects high-capacity switches across short to medium distances while minimizing fiber usage.Carrier Ethernet Services: Supports multiple service providers over a single fiber with controlled service hand-off.Hyperscale Computing: Ideal for Spine-Leaf topologies where port density and thermal management are critical.Cloud and VPN Access: Provides reliable, high-speed connectivity for business-class services.BenefitsFiber Savings: Reduces the number of fibers required for high-speed links, lowering infrastructure costs.Operational Simplicity: Compatible with existing QSFP-DD ports, enabling easy integration into current network architectures.Scalability: Supports future upgrades to higher data rates (up to 400G) without additional fiber deployment.Vendor Flexibility: Works with multiple switch and router vendors, allowing for flexible network design and OEM customization . In summary, the Nordic ODM Single-Fiber Bidirectional QSFP-DD is a cost-effective, high-performance solution for modern high-speed networks, combining QSFP-DD form factor compatibility with single-fiber bidirectional technology to maximize fiber efficiency and network scalability.
