Amphenol, TE Connectivity, and LINK-PP are key manufacturers offering OSFP optical modules and cable assemblies compatible with NRZ signaling.

Key Manufacturers and Offerings

Amphenol provides OSFP cable assemblies that support 25G/lane NRZ signaling, delivering aggregate bandwidths of 200G, 400G, 800G, and up to 1.6T per cable assembly. Their products are available in passive, active, and loopback variants, optimized for high-speed data center interconnects with heat-dissipative designs to maintain signal integrity at high data rates . TE Connectivity (TE) offers OSFP connectors and cable assemblies supporting 28G NRZ and higher PAM4 signaling. TE's OSFP solutions provide aggregate data rates from 200 Gbps up to 1.6T, with integrated thermal management and broad system compatibility, making them suitable for high-density, high-power network environments . LINK-PP is a full-stack optical module manufacturer delivering OSFP optical modules for 400G, 800G, and 1.6T networks. Their modules support high-density interconnects with complete optical, electrical, and mechanical integration, and are designed for AI/ML workloads, hyperscale networks, and large-scale switch fabrics. LINK-PP emphasizes thermal efficiency and high-speed packaging for next-generation cloud and AI data centers .

Technical Highlights

• NRZ Support: Typically 25–28G per lane, suitable for 200G–400G OSFP modules.
• Aggregate Bandwidth: Modules can scale from 200G to 1.6T depending on lane count and signaling type.
• Form Factor Advantages: OSFP supports 8-lane architecture, wider thermal envelope, and improved airflow compared to QSFP-DD, critical for high-density deployments.
• Applications: Data center interconnects, TOR/spine switches, AI clusters, and cloud computing environments. These manufacturers provide a comprehensive ecosystem for OSFP deployment, including optical engines, copper and optical cable assemblies, and thermal management solutions, ensuring compatibility with modern high-speed Ethernet architectures. For procurement, Amphenol and TE Connectivity products are widely available through distributors like DigiKey and Mouser, while LINK-PP typically works directly with OEMs and system integrators.
