Pin Description

The electrical interface to the transceiver is a 38 pins edge connector. The 38 pins provide high speed data, low speed monitoring and control signals, I2C communication, power and ground connectivity. The top and bottom views of the connector are provided below, as well as a table outlining the contact numbering, symbol and full description.

Module Memory Map

Compatible with CMIS rev 4.0/ SFF8636

Package Outline

The mechanical specifications are based on QSFP56 transceiver module specification, substituting the optical connectors with a cable connecting three ends.
