Home / Debugging OTN Router PAM4
Testing a transceiver for compliance to the specified requirements of a technology standard should assure that any signal that it transmits will be interoperable with any combination of other com.
Abstract PCI-Express (PCIe) and Ethernet/OIF-CEI standards share certain terminology and general test methods, but each technology addresses transmitter and receiver testing differently. 100+ Gb/s
