Product Description





C Band 75/100GHz 400G Coherent Module QSFP-DD ZR 80~120KM for DCI Applications



This product is a 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 product 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).
