FT-OSFP-1.6T-DR8D 1.6T OSFP DR8D PAM4 1311nm 500m Dual MPO-12 SMF Optical Transceiver Module
Engineered for the extreme bandwidth demands of large-scale AI/ML training clusters and hyperscale cloud networks, the OSFP-1.6T-DR8D delivers an aggregate data rate of 1.6Tbps using 8 lanes of 200G PAM4 signaling. Operating at 1311nm over Single Mode Fiber (SMF), it supports transmission up to 500m, making it ideal for intra-data center interconnects (DCI) and spine-leaf architectures.
This module features a Dual MPO-12 interface, enabling a native 2x 800G-DR4 breakout configuration to seamlessly bridge 1.6T switch ports with downstream 800G compute nodes or storage systems. Built on the hot-pluggable OSFP form factor with integrated thermal management (IHS/Finned Top support), it ensures reliable operation in high-density, air-cooled, and liquid-cooled environments while complying with OSFP MSA, IEEE 802.3dj, and CMIS Rev 5.x standards.
Key Features
Ultra-High Bandwidth: 1.6Tbps aggregate (8x 200G PAM4 electrical/optical lanes).
Twin-Port Architecture: Dual MPO-12 APC connectors supporting 1x1.6T or 2x800G (DR8D/2xDR4) modes.
Optimized Reach: 500m over G.652.SMF with FEC, tailored for AI pod and row-to-row connectivity.
Advanced Modulation: 212.5GBd PAM4 per lane for maximum spectral efficiency.
Thermal Robustness: OSFP housing designed for <30W dissipation with enhanced heat spreading.
Comprehensive Diagnostics: Digital Diagnostic Monitoring (DDM/DOM) via CMIS-compliant I²C interface.
Standards Compliance: Compliant with OSFP MSA, IEEE 802.3dj (Draft), CMIS 5.0+, and RoHS.
