Manufacturer s Optical Core Router OSFP

OSFP (Octal Small Form Factor Pluggable) modules are high-performance optical transceivers supporting 400G, 800G, and 1. 6T speeds, widely used in modern data centers and AI-scale networks.

Overview of OSF

P TechnologyOSFP modules are designed for high-density, high-speed optical connectivity with enhanced thermal management and electrical scalability. They support power budgets up to 60W, enabling sustained performance in AI clusters and GPU-to-GPU topologies. The native 8-lane architecture allows seamless upgrades to higher speed classes without changing the mechanical form factor, making OSFP ideal for ultra-dense switch and router deployments.

Key Features and BenefitsHigh-Speed Connectivity: Supports 400GE, 800GE, and emerging 1. 6Tbps links, with breakout options such as 8x100G or 2x400G for flexible network scaling. Thermal Efficiency: Larger housing and improved airflow paths compared to QSFP-DD, critical for power-intensive applications.

Interoperability: Compliant with IEEE 802. 3 standards, CMIS 5. 3, 400ZR/800ZR, OpenZR+, and OpenROADM MSA agreements, ensuring compatibility across multiple vendors and network layers.

Deployment Flexibility: OSFP modules support short-reach (50–500m), medium-reach (2 km), and long-reach (up to 10 km or 120 km with coherent designs) applications, suitable for intra-data center, metro, and service provider networks.

Acacia: Supplies OSFP modules powered by Delphi DSP ASICs and silicon photonics, supporting DCI, metro, and service provider networks with coherent 800G pluggables and extended reach up to 120 km.

C-LIGHT: Offers 1. 6T OSFP-RHS transceivers for next-generation data centers, along with 400G and 800G OSFP modules for various distances, optimized for AI, HPC, and hyperscale GPU clusters.

Deployment Considerations

When integrating OSFP modules into optical core routers, network engineers should consider: Thermal management for high-power modules, especially in dense racks. Compatibility with existing switch/router ports and breakout configurations. Line rate and reach requirements to select the appropriate OSFP variant (SR, DR, FR, LR, or coherent).

Future scalability to support emerging 1. 6T speeds without redesigning the front panel.

OSF

P modules are increasingly the preferred choice for modern data centers, AI clusters, and high-performance optical networks, offering a balance of high bandwidth, thermal efficiency, and interoperability across multiple vendors.
