FireFly Brochure

12x14G FireFly Module (12Tx and 12Rx)



The FireFly™ Micro Flyover System™ is the first interconnect system that gives designers 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 (14Gb on this module with 28G in development). 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 ECUE Ribbon Coax Cable features

  • Performance up to 28 Gbps (14Gbps supported by the HTG-ZR-FF module with 28Gbps in development).
  • A large variety of end two connector termination options
  • 50Ω 38 AWG micro ribbon coax cable
  • Capability to enable test and verification of connectors during manufacturing
  • Lower-cost AcceleRate 100Ω 30 AWG twinax ribbon system for improved signal integrity and lower profile

The ECUO Active Optical Cable assembly features

  • x12 unidirectional or bidirectional transceiver system
  • 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®





The module uses high-performance ZRAY port interfacing to Xilinx and Altera FPGAs.

Z-Ray® micro array interposer is ultra-low profile, high density, highly customizable compression contact arrays used as interposers or as board level interconnects. Compared to standard interposers, they feature greater density, X-Y-Z axes flexibility, customizable shapes and patterns, increased cycle life, low normal force with high deflection range and 28+ Gbps performance. HiTech Global is using Z-Ray connectors in conjunction with high-speed serial transceivers (up to 14Gbps) of FPGAs for daughter card and board-to-board interfaces. The HTG-ZRAY bus provides the most optimized performance and the best signal integrity.
