The FT-OSFP-XD-1.6T-2FR4 is a high-density 1.6T optical transceiver module designed for next-generation AI fabrics, cloud data centers, and high-performance computing interconnects. Housed in the OSFP-XD ('eXtra Dense') form factor, this module doubles the electrical lane count from 8 to 16, delivering 1.6Tbps aggregate bandwidth using 16 lanes at 100G PAM4 signaling—while remaining fully compatible with existing 100G electrical lane switch infrastructures.

Operating at 1311nm CWDM4 wavelength grid, the module supports dual-channel FR4 transmission over standard single-mode fiber (SMF) with a reach of up to 2km via dual duplex LC connectors. It integrates 2×FR4 optical engines in a compact package, enabling flexible 1×1.6T or 2×800G breakout configurations to accommodate diverse network deployment scenarios.

Built with low-power DSP technology and an optimized IHS/Finned Top thermal design, the FT-OSFP-XD-1.6T-2FR4 ensures robust performance even in high-density, high-heat rack environments. It provides a seamless, cost-effective upgrade path for hyperscalers and enterprises transitioning from 800G to 1.6T networks.
