The QSFP-DD ER4 transceiver is a 400 Gbit/s pluggable module for optical data communications such as 400GBASE Ethernet. The transceiver operates with four parallel data streams of 106.25Gbps in order to provide an aggregated signaling rate of 425 Gbps. The four lanes are launched with center wavelengths of 1304.58nm, 1306.85nm, 1309.14nm and 1311.43nm and multiplexed onto singlemode fiber. On the receive side, the four lanes of optical data streams are de-multiplexed by the transceiver and retimed.
The module is fully compliant with QSFP-DD related MSA standards and Digital Diagnostic functions are available through an I2C interface.
