Custom Tunable Optical Module OSFP

Tunable OSFP modules are high-performance, pluggable optical transceivers designed for scalable, high-speed data center and hyperscale networks, supporting 400G, 800G, and emerging 1. 6T bandwidths with advanced thermal and electrical management.

Overview of OSFP

The Octal Small Form-

Factor Pluggable (OSFP) standard is an open, vendor-neutral interface designed for high-density, high-speed optical connectivity in modern data centers, AI clusters, and hyperscale environments.

OSF

P modules support eight electrical lanes, each capable of 50G, 100G, or 200G PAM4 signaling, enabling total bandwidths of 400G, 800G, and 1. 6T depending on the module generation. Unlike QSFP-DD, OSFP prioritizes thermal headroom, electrical performance, and future scalability, making it ideal for AI and GPU-intensive workloads.

Tunable Optical Capabilities

Tunable OSF

P modules allow dynamic adjustment of the optical wavelength, which is critical for Dense Wavelength-Division Multiplexing (DWDM) applications. This tunability enables: Flexible deployment across multiple channels without changing hardwareOptimized spectrum utilization for metro, regional, and data center interconnectsSupport for 800ZR and 800G ZR+ coherent optics, achieving distances up to 120 km for 800ZR and beyond 1000 km for 800G ZR+ Tunable modules leverage advanced DSP ASICs and silicon photonics, providing high-performance signal processing, low power consumption, and interoperability with OIF, OpenZR+, and OpenROADM standards.

Thermal and Electrical DesignOSFP modules are engineered for high thermal dissipation, with integrated heatsinks supporting 30–60W power budgets for 1. 6T modules. The form factor ensures efficient airflow and cooling, critical for AI cluster deployments and high-density switch configurations.

Electrical design supports break-out applications and maintains backward compatibility with previous OSFP generations, ensuring smooth upgrades from 400G to 1. 6T.
