“Do you know how FAST you were going?!?”
That question strikes fear in almost all teenage drivers. The resulting ticket dashes any hope of a fun weekend. Plus, what happens when the parents find out?? No!!!
Meanwhile, embedded and optical engineers may wonder the same thing. “PCIe 3.0 only gets to 8 GT/s? I need more speed!” So what’s the answer? PCIe 4.0 over fiber solutions, of course.
Why PCIe 4.0 Over Fiber?
Any number high-performance, embedded applications are looking for three things: faster data rates, lower latency and small form factors. Target applications run the gamut from Mil/Aero and scienific, to emedded, simulation and real-time applications.
PCIe may have started as the standard internal interface for connecting MCUs and I/O Controllers on a motherboard. Now, PCIe over fiber links hosts and endpoints up to 100 m away in a lab, data center or on the factory floor. All of this with low latency and a small form factor.
What’s the secret?
FireFly™ Micro Flyover System™
The Samtec FireFly Micro Flyover System is the first interconnect system that gives a designer the flexibility of using micro footprint high-performance optical and low-cost copper interconnects interchangeably with the same connector system.
Samtec FireFly™ copper and optical cable systems provide the flexibility to achieve higher data rates to 28 Gbps and/or greater distances, simplifying board design and enhancing performance.
Samtec’s PCI Express®-Over-Fiber FireFly™ Optical Cable Assemblies offer key features that solve the challenges of transmitting the PCIe protocol over longer links. The latest edition supports PCIe 4.0 (16 GT/s) data rates.
The miniature size of Samtec’s high-density optical engines allows them to be easily designed into the downstream system, ultimately making these systems smaller. Highly flexible, small diameter, industry standard optical patch cords provide connection to the control system.
PCIe 4.0 Over Fiber Host / Target Adapters
Samtec and Dolphin ICS have jointly developed a growing family of PCIe Adaptor cards ideally suited for high-performance optical clustering and embedded computing applications.
Based on the latest PCI Express® bridging architectures and Samtec’s PCIe-Over-Fiber FireFly optical cable solution, the combined solutions offer transparent and non-transparent bridging (NTB) over long distance PCIe. Plus, it’s small form PCI Express Low-Profile Half-Length form factor!
