400G QSFP-DD DR4 500m

The Arkoptics' 400GBASE-DR4 transceiver is a four-channel QSFP-DD optical transceiver module designed for 400 Gigabit Ethernet (GbE) links on up to 500m over single mode fiber using a nominal wavelength of 1310nm. An optical fiber cable with an MTP/MPO-12 connector can be plugged into the QSFP-DD DR4 module receptacle. The module adopts a 1310nm EML transmitter type and PAM4 pulse amplitude modulation mode. It converts 8 channels of 50Gb/s PAM4 electrical input data to 4 channels of parallel optical signals, each capable of 100Gb/s operation for an aggregate data rate of 400Gb/s. Reversely, on the receiver side, the module converts 4 channels of parallel optical signals of 100Gb/s each channel for an aggregate data rate of 400Gb/s into 8 channels of 50Gb/s(PAM4) electrical output data.

The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP-DD Multi-Source Agreement (MSA) Type 2. It is compliant with the QSFP-DD MSA, IEEE 802.3bs and 400GBASE-DR4. It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference, widely used in high-performance computing (HPC) networks, data centers, 400G Ethernet interconnect, enterprise core, and distribution layers, and service provider applications.
