It is designed for next-generation 1.6T data center networks and InfiniBand fabrics. The 1.6T OSFP 2xFR4 module adopts a dual FR4 architecture (2xFR4), providing 8 optical channels in total, with each port carrying 4x200G-PAM4 lanes. Optical signals are transmitted using CWDM4 serial multiplexing on the 1310nm wavelength grid, enabling efficient high-density, long-reach transmission. For physical connectivity, the transceiver uses two LC duplex connectors, each operating over two single-mode fibers, supporting far-reach FR4 links while maintaining compact port density in OSFP form factors. The connector housing features a RHS\/flat top design, enhancing thermal dissipation and ensuring optimal space compatibility in high-density switch deployments.\n\nThe OSFP-1.6T-2FR4FH integrates Silicon Photonics chips and the Broadcom 3nm Sian3 (BCM83628) DSP to deliver 1.6Tb\/s optical performance with high signal integrity and energy efficiency. Designed for liquid-cooled 1.6T switch-to-switch interconnects, it supports scalable deployment of next-generation InfiniBand fabrics in AI and HPC data centers.","brand":"SFPS","offers":[{"title":"OSFP-1.6T-2FR4FH","offer_id":47934149001437,"sku":"46-SFPS-OSFP-1.6T-2FR4FH","price":3623.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/7539\/1197\/files\/Product6726-1.png?v=1779070648","url":"https:\/\/www.sfps.qa\/products\/46-sfps-osfp-1-6t-2fr4fh","provider":"SFPS.QA","version":"1.0","type":"link"}
