QSFPDD 400G DR4 500M SFP Transceiver MPO Connector
This product is a 400Gb/s Quad Small Form Factor Pluggable-double density (QSFP-DD) optical module designed for 500m optical communication applications. The module 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 module incorporates 4 parallel channels on 1310nm center wavelength, operating at 100G per channel. The transmitter path incorporates a quad channel EML driver together with 4 parallel EMLs. On the receiver path, a PD array is connected with a quad channel TIA to convert
the parallel 400Gb/s optical input into 4 channels of parallel 100Gb/s (PAM4) electrical signals. A DSP basis gearbox is used to convert 8 channels of 25GBaud PAM4 signals into 4 channels of 50GBaud PAM4 signals and also an 8-channel retimer and FEC block are integrated in this DSP. The electrical interface is compliant with IEEE 802.3bs and QSFP-DD MSA in the transmitting and receiving directions, and the optical interface is compliant to QSFP-DD MSA with MPO-12 connector.
