Samtec FireFly™ Mid-Board Optical Transceiver Solutions
Samtec's FireFly™ Micro Flyover System™ embedded and rugged optical transceivers take data connection "off board" for up to 28 Gbps per lane with a path to 112 Gbps PAM4 via optical cable at greater distances, or copper for cost optimization.
Samtec is the industry-leading provider of mid-board optical transceiver solutions. This growing and comprehensive family of products provides reliable signal integrity over an extended distance in chip-to-chip, board-to-board, on-board and system-to-system connectivity that takes data connection "off board" for up to 28 Gbps per lane with a path to 112 Gbps PAM4 via optical cable at greater distances, or copper for cost optimization.
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.
Highest Density
The industry-leading miniature footprint of FireFly™ allows for greater density and closer proximity to the IC, which simplifies board layout and enhances signal integrity. Performance from 14 Gbps to 28 Gbps can be achieved in the same footprint covering an area of only 0.63 square inches for an aggregate 265 Gbps/in².
Ease of Routing
The two-piece board level interconnect system consists of a micro high-speed edge card connector, and a positive latch connector for power and control signal communications. Isolating the signal and power in this manner helps ease trace routing, compared to array systems.
UEC5 – High-Speed Edge Card Connector
- Gen 1 – up to 20 Gbps
- Gen 2 – 20+ Gbps
UCC8 – Positive Latch Connector
Ease of Assembly
The rugged two-piece edge card socket system, with weld tabs, latch locking mechanism, and loading guides, provides simplified mating and unmating of the cable assembly, compared to compression systems, which utilize mechanical screw downs and hardware.
Unlike existing optical engine-based solutions, thermal operating conditions are acknowledged and designed for by including an integral heat sink. This integral heat sink further simplifies the assembly process. Standard heat sinks are available in several designs, including finned, flat, fiber-groove for multi-row configurations, and custom designs, for conduction or convection cooling.
Signal Integrity
By taking the data connections “off-board” with Samtec Flyover® cables, the signal integrity design is made significantly easier, and the electrical performance improved.
Routing data above lossy board materials and other signal degrading components negates the need for the layout complexities that are required to design for high speed signaling.
