Micro Flyover System Patented The FireFly™ Micro Flyover System is the first interconnect system that gives the designer a choice of using either micro footprint optical or copper interconnects to meet today’s data rate requirements and the next generation. The FireFly™ system enables chip-to-chip, board-to-board, on-board and system-tosystem 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.

FIREFLY™ EVALUATION KIT Samtec’s FireFly™ Evaluation 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 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.
