Abstract
Mass-manufactured cables suitable for large communication centers may convert from differential PAM4 interface signaling to parallel single-ended NRZ transit signaling at 53.125 GBd to provide bidirectional data rates up to 800 Gbps and beyond. One illustrative cable embodiment includes: electrical conductors connected between a first connector and a second connector, each adapted to fit into an Ethernet port of a corresponding host device to receive an electrical input signal to the cable conveying an outbound data stream from the host device and to provide an electrical output signal from the cable conveying an inbound data stream to that host device. The electrical input and output signals employ differential PAM4 modulation to convey the inbound and outbound data streams. Each of the first and second connectors includes transceivers to perform clock and data recovery on the electrical input signal to extract and re-modulate the outbound data stream for transit via the electrical conductors as respective pairs of electrical transit signals employing single-ended NRZ modulation.
