Yiyuan 400G QSFP-DD DR4 1310nm 500m MPO-12 Single-Mode Optical Transceiver

Yiyuan 400G QSFP-DD DR4 Single-Mode Optical Transceiver | PAM4 | 1310nm | 500m | MPO-12/APC | DOM

The Yiyuan 400G QSFP-DD DR4 transceiver delivers 400Gbps over 500 meters of single-mode fiber using 4×100G PAM4 parallel channels at 1310nm. With MPO-12/APC connectors, it bridges the gap between short-reach multimode and long-reach DCI applications — ideal for campus-scale data center interconnects and extended spine-layer links.
