Anritsu and KYOCERA Complete World’s First Successful PCI Express 5.0 Optical Signal Transmission Test

Anritsu and KYOCERA Complete World’s First Successful PCI Express 5.0 Optical Signal Transmission Test


Anritsu Corporation and KYOCERA Corporation have completed a successful PCI Express 5.0 optical transmission test using Anritsu’s Signal Quality Analyzer-R MP1900A and KYOCERA’s on-board optics module. This world’s first test converted a PCIe 5.0 (32Gbps transmission speed) electrical signal into an optical signal using an end-point Add-in Card (AIC).

Advanced value-added services such as 5G, IoT and Cloud applications are spreading rapidly, creating unprecedented demand for faster data speeds and larger data capacities. However, today’s power-intensive data centres face cost and sustainability issues as they increase transmission speeds and capacity. This Anritsu/KYOCERA test converted an electrical signal into an optical signal at an early stage by mounting an on-board optics module – greatly miniaturised through KYOCERA’s multilayer ceramic technology – close to the host (an MP1900A simulating a CPU output signal for test purposes). The test verified that the E/O-converted signal was transmitted at the PCIe 5.0 standard 32Gbps speed to the endpoint located 25m from the host. In addition, the successful optical signal transmission test proved the potential for this technology to reduce data centre power consumption through lower signal loss. In the future, signal transmission between servers will not use ethernet due to power consumption issues and latency. Instead, servers will use direct PCIe connections. 

Operators of next-generation data centres using PCIe optical signal transmission will enjoy the business benefits of lower power consumption and reduced latency. With this successful test, Anritsu and KYOCERA are helping to solve the evolving challenges of tomorrow’s digital society.

Due to its miniaturised form factor, KYOCERA’s on-board optics module facilitates easy processor-adjacent mounting to both convert electrical signals from the processor at the earliest possible stage, and cut wiring losses when sending/receiving electrical signals.
