Introduction to the 400G QSFP112 DR4
The 400G QSFP112 DR4 Optical Transceiver is designed for 400Gb/s network applications, including 400GBASE-DR4 Ethernet and data center applications. It supports a maximum transmission distance of 500m over single-mode fiber (SMF) and operates at a 1310nm wavelength. This 400G DR4 optical transceiver uses four optical lanes, each running at 106.25Gbps, to provide an aggregated data rate of 425Gbps.
The 400G QSFP112 transceiver complies with the QSFP112 MSA, 400GBASE-DR4 optical specifications, IEEE Std 802.3bs for 400Gb/s optical interfaces, and IEEE Std 802.3ck for 400Gb/s electrical interfaces. It features an MPO-12 receptacle, a 1310nm EML laser, and a 4 × 53.125 GBd PAM4 electrical interface.
With a single +3.3V power supply and a commercial operating temperature range of 0°C to +70°C, this 400G 500m optical transceiver is designed for data center applications. It also complies with RoHS requirements.
