Link Diagnostics in LPO Applications Abstract: Network equipment comprised of Linear Pluggable Optics (LPO) modules and host ASICs provides a full suite of capabilities for link monitoring and
The assumption is that TP1 is equivalent to B on the host testing and B'' on the module testing and TP4 is equivalent to C on the host C'' on the module. Assumes that the connectors and compliance
From the eye diagram the following information needs to be extracted: the rise and fall times (20%-80%) of the signal waveform, the jitter in the serial bit stream triggered with the reference (frame) clock, the
At the physical layer, electrical signals (TP1/TP4) and optical signals (TP2/TP3) are tested. Mainstream vendors such as Tek and Keysight support physical-layer testing for PAM4.
The receiver section includes a Receiver Optical Sub‐ Assembly (ROSA), pre‐amplification and post‐amplification circuit, Clock and Data Recovery Circuit and an electrical output stage with
Both TP2 and TP3 are optical signals of the serial bit stream. TP4 is the electrical signal at the input of the deserializer. Both TP1 and TP4 are electrical signals of the serial bit stream. TP5 is at
