Samtec, a privately held $625M global manufacturer of a broad line of electronic interconnect solutions, proudly announces the release of an extended temperature version of its FireFly™ Active Optical Micro Flyover Cable Assembly. The new ETUO series support temperature ranges of -40° to +85°C.

The ETUO series shares the core features of Samtec’s existing ECUO series FireFly™ Active Optical Micro Flyover Cable Assembly. Both are designed for flexibility and are interchangeable with the FireFly™ Copper Micro Flyover Cable Assembly using the same connector system. However the extended temperature range of ETUO makes it ideally suited for ruggedized applications.

The ETUO series is immediately available with 12-channel simplex or duplex configurations enabling 10.3125 Gbps data rates per channel (123.75 Gbps aggregate). Additional 4-channel simplex and duplex configurations with extended temperature are under development with a targeted Spring 2017 release.

Samtec tests the ETUO series to industry-standard ruggedized standards. All ETUO solutions provided demonstrated error-free transmission during MIL-STD-810G shock and vibration testing.

“Samtec’s new extended temperature FireFly™ Active Optical Micro Flyover Cable Assembly opens new markets and applications for mid-board optical systems, “ says Matt Burns, Technical Marketing Manager at Samtec. “FireFly™ can now be used in diverse applications such as commercial and military aviation, IFE, IR cameras and wireless backhaul instrumentation.”
