A: Host Interface
The module support for wide applications with Host interfaces: CAUI-4 and 100GAUI-2. The Host
interface conform to existing protocol standards and operate over standard physical layer specifications. The
termination, mapping and/or aggregation of this signal is into an internal frame structure. The frame structure is
then adapted to the FEC engine and DSP framed for transmission over the coherent media Interface. The Host
interface signaling conform to existing protocol and electrical standards as defined by IEEE 802.3TM-2018.

B: Media Interface
The media interface utilizes DP-QPSK modulation, polarization diversity coherent detection, and
advanced electronic link equalization with chromatic dispersion and differential group delay compensation.
The module terminates the host interface signal(s) then maps and/or aggregates them into an internal frame
structure. The frame structure is then adapted to the FEC engine and DSP framed for transmission over the
coherent Media interface.

The application field of the module is widely used for short/metro haul. As shown in figure1, it is comprised of
high-data lanes, a single 3.3V power supply, an IIC interface for module control and status report, and dedicated
alarm and control pins (not shown on the figure1)
