What is the advantage of a 100G BiDi transceiver compared with a traditional duplex 100G module?

A 100G BiDi transceiver uses two wavelengths to transmit and receive data over a single fiber, while traditional duplex modules require two fibers. This helps reduce fiber usage, simplify cabling, and maximize existing fiber infrastructure capacity.

How do the 1271nm and 1331nm wavelengths enable bidirectional transmission?

The module uses wavelength division technology, where one wavelength is used for transmitting signals and the other wavelength is used for receiving signals. This allows two-way communication through the same optical fiber without interference.

Is this module compatible with standard 100G QSFP28 ports?

Yes. The module uses a standard QSFP28 form factor and CAUI-4 electrical interface, making it compatible with network equipment supporting 100G QSFP28 optical modules and 100GBASE-LR1-10 BiDi applications.

Why does this module use PAM4 modulation?

PAM4 modulation allows higher data transmission rates by carrying multiple bits per symbol. It enables 100Gb/s optical transmission while maintaining compatibility with QSFP28 electrical interfaces and improving bandwidth efficiency.

What diagnostic functions are supported by this transceiver?

The module supports digital diagnostic monitoring through the I2C interface, allowing monitoring of operating parameters such as temperature, voltage, optical power, and module status. TX_DIS and RX_LOS functions provide additional control and fault detection capabilities.
