RS OSFP-1.6T-2DR4FH is a 1.6Tb/s twin-port OSFP224 optical transceiver compatible with NVIDIA/Mellanox MMS4A00-XM-FLT (980-9IAH0-00XM00) , supporting InfiniBand and Ethernet networks with 2 × 800Gb/s links. It is designed for high-performance data center interconnects and next-generation HPC applications. The 1.6T OSFP 2xDR4 transceiver features a parallel 8-channel design (2x DR4/DR8) over single-mode fiber, utilizing 200G-PAM4 electrical and optical modulation. Each port connects via a 4-channel MPO-12/APC optical connector, enabling 800Gb/s per connector. The transceiver supports a maximum fiber reach of 500 meters over 8 single-mode fibers, providing reliable medium-distance links within the data center. The OSFP224 housing incorporates a Flat Top/RHS design for improved heat management and stable operation in densely packed switch environments. The 1.6T OSFP 2xDR4 transceiver supports dual optical solutions: in-house silicon photonics (SiPh) and mature EML technology, achieving higher integration, lower power consumption, and greater port density, while the Broadcom 3nm Sian3 (BCM83628) DSP delivers robust PAM4 signal processing with ultra-low bit error rates (BER) and stable link performance, enabling reliable, low-latency 800G/1.6T interconnects. This transceiver is ideal for 1.6T liquid-cooled switch-to-switch interconnects, providing high-bandwidth, low-latency links in InfiniBand XDR, AI, and HPC data center networks.
