400G QSFP-DD SR8 Optical Transceiver, Compatible with QDD-400G-SR8-S, 850nm, 100m Over OM4, MPO-16/APC, DOM, 400GBASE-SR8 Ethernet Module

COMPATIBLE WITH QDD-400G-SR8-S: Third-party replacement transceiver for compatible 400GbE QSFP-DD ports. Verify your switch model, software version and transceiver support before ordering. Not manufactured by .
400GBASE-SR8 ETHERNET CONNECTION: Features eight 50G PAM4 optical lanes operating at 850nm for short-reach 400 Gigabit Ethernet connections between compatible network devices. Suitable for data center switch interconnects and high-bandwidth network deployments.
UP TO 100M OVER OM4 MULTIMODE FIBER: Supports link distances up to 100 meters over OM4 or 70 meters over OM3 multimode fiber, subject to the supported optical link budget. Uses an MPO-16/APC interface; matching fiber cable is required and sold separately.
DIGITAL OPTICAL MONITORING: DOM enables supported host equipment to monitor module temperature, supply voltage, laser bias current and optical transmit/receive power. Available readings and management functions depend on the host platform and software.
CHECK PORT AND FIBER COMPATIBILITY: Designed for QSFP-DD hosts supporting 400GBASE-SR8. Not for QSFP112, QSFP56 or QSFP28 host ports, and not for direct insertion into NVIDIA DGX Spark. Requires matching MPO-16/APC connectivity; not interchangeable with MPO-12 or MPO-16/UPC cables.
