QDD-400G-DR4 400G OSFP-DD DR4 PAM4 500m Parallel SMF MPO-12 Optical Transceiver

The 400G QSFP56-DD DR4 optical module is a type of high-speed transceiver module used in data communication and networking applications. It has a QSFP56-DD form factor, which is a compact and hot-pluggable interface that supports high-speed data transfer over optical fiber cables.

The "DR4" in the module's name stands for "dense wavelength division multiplexing (DWDM) with four channels," meaning that the module has four separate channels for transmitting and receiving data. The module uses four fiber pairs, with each pair transmitting data at a rate of 100 Gbps, resulting in a total bandwidth of 400 Gbps.

This type of module is commonly used in data centers and high-performance computing environments where fast and reliable data transfer is essential.
RTXM500-400 400G QSFP-DD DR4 transceiver modules are designed for use in 400 Gigabit Ethernet links on up to 500m of single mode fiber. They are compliant with the QSFP-DD MSA, IEEE 802.3bs and 100G Lambda MSA.The optical transceiver is RoHS compliant.
