400G QSFP-DD DR4 optical module uses a standard MPO-12 connector to transmit up to 500m over single-mode fiber. The Transceiver complies with QSFP-DD MSA, IEEE 802.3bs protocol, and 400GAUI-8 standard. 400 Gigabit Ethernet signals are transmitted over four parallel channels on one wavelength per channel. It can also be connected to 100G DR optical modules. It adopts a 1310nm EML transmitter type and PAM4 pulse amplitude modulation mode. It is used in data centers, high-performance computing networks, enterprise cores, distribution layers, and service provider applications.
