FireFly™ Micro Flyover System™

Future Proof system easily upgrades from copper to optical using the same connector system.
Highest 14 Gbps bandwidth density available.


FAMILY OVERVIEW

The FireFly™ Micro Flyover System™ is the first interconnect system that gives a designer the flexibility of using micro footprint optical and copper interconnects interchangeably with the same connector system.

The FireFly™ system enables chip-to-chip, board-to-board, on-board and system-to-system connectivity at data rates up to 28 Gbps. FireFly™ is based on a high performance interconnect system which allows the use of low-cost copper cables or high performance active optical engines.

Samtec copper, equalized copper, and optical cable systems provide the flexibility to achieve higher data rates and/or greater distance needs while simplifying board design and enhancing performance.

The Firefly™ Micro Flyover System is the first interconnect system that gives designers a choice of using either micro footprint optical or copper interconnects to meet today's data rate requirements and the next generation.

FEATURES

Future Proof

The FireFly™ Micro Flyover System™ is the first inside-the-box interconnect system that gives designers a choice of using either micro footprint high performance active optical engines or low-cost copper interconnects. This allows the designer to upgrade from electrical to optical FireFly™ using the same connector system.

The ECUE Twinax Ribbon Cable features:

  • Performance up to 28 Gbps
  • A large variety of end two connector termination options
  • 100 Ω 34 or 36 AWG twinax ribbon cable
  • Capability to enable test and verification of connectors during manufacturing; allowing early diagnosis of data connectivity issues
  • Low profile housing for space savings
  • Passive and active equalization for improved performance over same distance, or for even longer cable lengths

The ECUO Active Optical Cable features:

  • x12 simplex or duplex transceiver system
  • x4 simplex or duplex systems in development
  • 14 Gbps or 28 Gbps (in development) channel system
  • Proven 850 nm VCSEL array technology
  • Available in panel mount or full Tx-to-Rx active optical cable
  • Protocol agnostic and supports all data center and HPC protocols including Ethernet, InfiniBand™, Fibre Channel, PCIe®
  • Extended temperature system (ETUO Series) designed with a -40 ºC to +85 ºC range to handle harsh environments is in development

Highest Density

FireFly™ has the highest 14 Gbps bandwidth density available. FireFly™ is a x12, 14 Gbps per channel system with an aggregate 168 Gbps. These 12 duplex channels cover an area of .63 square inches, for an effective 265 Gbps per square inch. A 28 Gbps bandwidth system is in development with an aggregate 336 Gbps.

Ease of Routing

The two-piece board level interconnect consists of a micro high speed edge card connector providing 12 differential lanes, and a 10 position 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.

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 air cooling or with cold plate liquid cooling.

Signal Integrity

By taking the data connections "off-board" with FireFly flyover cables, the signal integrity design is made significantly easier, and the electrical performance improved.

Allowing data to "fly over" lossy board materials and other signal degrading components negates the need for the layout complexities that are required to design for high speed signaling.

Evaluation Kit

This kit allows the designer real-time evaluation of an actively running copper or electrical FireFly system. The designer has the flexibility to test and characterize the system in their lab, with their inputs. The evaluation board connects the FireFly connector system (UEC5/UCC8 Series) to a 24-position Bulls Eye® system and brings the low speed signals and power rails to various standard connectors. The Bulls Eye® system allows for connecting all 12 FireFly channels to various laboratory test equipment. A second Bulls Eye® connector landing pad enables the de-embedding of the Bulls Eye® interconnect and PCB effects on the high speed signals. The FireFly Evaluation Kit is rated up to 25 Gbps.
