QSFP-DD 4*100Gbps transceiver module is designed for optical communication applications in 400 Gigabit Ethernet links over 2km single mode fiber. This product has 8 independent electrical input/output channels which can convert 50Gbps (PAM4) electrical input data to 4 channels of 100Gbps (PAM4) parallel optical signals. Also, it converts 4 channels of parallel optical signals of 100Gbps (PAM4) for each channel into 8 channels of 50Gbps (PAM4) electrical output data. The module incorporates 4 parallel channels on a 1310nm center wavelength, operating at 100G per channel. The electrical interface of the module is compliant with the 400GAUI-8 interface as defined by IEEE 802.3bs, and compliant with QSFP-DD MSA.
