400G QSFP56-DD LR4 10km Optical Transceiver RTXM500-416 CWDM EML Original
QSFP56-DD LR4 stands for Quad Small Form-factor Pluggable 56 Double Density Long Range 4. It is a type of optical transceiver module used in data centers and high-performance computing networks.
The QSFP56-DD LR4 module supports a data transfer rate of up to 200Gbps and can transmit data over long distances using single-mode fiber optic cables. The LR in QSFP56-DD LR4 stands for "Long Range," which indicates that this module is designed to transmit data over distances of up to 10 kilometers.
The "4" in QSFP56-DD LR4 refers to the four lanes of data transmission used by the module, which means it uses four lasers to transmit data. This makes it possible to achieve high data transfer rates over long distances.
Overall, the QSFP56-DD LR4 module is a high-speed, high-bandwidth solution for data centers and other applications that require high-speed data transfer over long distances using multiple lanes of data transmission.
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.
