- Adaptive Tx input equalization.

- Programmable Rx output amplitude, pre-cursor, and post-cursor.

- Monitoring capabilities for supply voltage, transceiver case temperature, Tx optical power for each lane, Tx bias current, and Rx optical power.

- Warning and alarm indications for each DDM function.

- Tx & Rx LOL and LOS indications, and Tx fault indications.

- Capabilities for both host and line side loopback, PRBS generation/checking, and CDB firmware upgrades.

- Versatile diagnostics monitoring (VDM) – optional feature with additional power consumption.

**Applications:**

The transceiver is apt for a variety of use cases including Ethernet, Telecom, and Infiniband. It supports multiple application configurations as per the CMIS definition:

1. 2x400G FR4 - Two sets of 400G per port breakout connections.

2. 2x200G FR4 - Two sets of 200G per port breakout connections.

3. 8x100G FR - Eight 100G per port breakout connections.

4. 1x800G FR8 - One 800G per port point-to-point connection.

For backward compatibility applications, please refer to the detailed application list. It's worth noting that mixed applications of cases 1 and 3 are also supported.
