Description:
The 400G QSFP-DD-ZR4 80KM coherent module, compliant with the OIF 400ZR MSA and QSFP-DD
MSA standards, is designed for DCI applications. The digital diagnostics function is available via an I2C
interface, as specified by the QSFP-DD MSA.
The 400G QSFP-DD-ZR4 80KM is a C-band 75G/100 GHz grid coherent optical module that combines
coherent DSP ASIC functionality with best in class ultra-narrow line-width tunable lasers, high speed
modulators and high responsively coherent receivers to deliver high performance at 400G 16QAM
modulation formats (at 60G baud rate).
