800GBASE 2×DR4 / DR8 QSFP-DD PAM4 Optical Transceiver
(SMF, 1310 nm, 500 m, Dual MPO-12 APC, DOM)
The 800GBASE 2×DR4 / DR8 QSFP-DD optical transceiver module is designed to deliver 800 GbE Ethernet connectivity over distances of up to 500 meters on OS2 single-mode fiber (SMF) at a wavelength of 1310 nm. The module uses dual MTP/MPO-12 APC connectors and supports both 2×400G DR4 and 8×100G DR8 breakout configurations.
Fully compliant with QSFP-DD MSA HW Rev 7.0, CMIS Rev 5.0, and IEEE 802.3cu / 802.3ck standards, the transceiver ensures interoperability across modern 800G network platforms. Integrated Digital Optical Monitoring (DOM/DDM) provides real-time visibility into critical operating parameters.
Optimized for low latency, low power consumption, and high reliability, this transceiver is ideal for 800G Ethernet, data center interconnect, high-performance computing (HPC), enterprise core and distribution networks, and service provider infrastructure.
