Transceiver : NVIDIA/Mellanox Compatible 200GBASE-SR4 / InfiniBand HDR QSFP56 Optical Transceiver Module, 850nm VCSEL Transmitter, PIN Receiver Array, Up to 100m Reach over OM3/OM4 Multimode Fiber (MMF), MPO-12/APC or MTP-12 APC Connector, DOM/DDM Support, 4x50.128Gb/s PAM4 Electrical/Optical Modulation, Max Power Consumption ≤4.5W

The NVIDIA/Mellanox Compatible 200G SR4 QSFP56 Optical Transceiver Module is a high-performance 200Gb/s 4-channel optical transceiver designed for demanding High-Performance Computing (HPC), AI supercomputing, and cloud data center environments. Utilizing 4 independent 50.128Gb/s PAM4 optical channels at an 850nm wavelength, this transceiver converts electrical data for up to 100 meters high-speed transmission over multimode fiber (MMF).

Engineered with an MPO-12/APC (Angled Physical Contact) connector interface, this QSFP56 transceiver minimizes optical back reflection to maximize signal integrity in high-density optical fabrics. It fully complies with InfiniBand HDR protocols, QSFP56 MSA standards, IEEE 802.3cd 200GBASE-SR4, and 200G Ethernet specifications. Equipped with integrated Digital Diagnostic Monitoring (DOM/DDM) via the I2C interface, it offers real-time monitoring of operating temperature, supply voltage, laser bias current, and transmit/receive optical power. It is 100% verified for seamless plug-and-play compatibility with NVIDIA Quantum QM8700 / QM8790 InfiniBand Switches and ConnectX-6 / ConnectX-7 Network Interface Cards (NICs / HCAs).
