Curtiss-Wright’s rugged Ethernet switches are specifically designed to meet harsh aerospace environments and reliably deliver high-speed real-time data. They are deterministic and compact with wide temperature operation from -40 to 85°C. Rapid boot-up minimizes data loss from power outages while flexible forwarding and filtering configurations can send what is required to multiple destinations for real-time monitoring, recording, and transmission.
They support IEEE-1588 PTP, some with embedded v1 and v2 Grandmaster support and translation, and GPS and digital IRIG-B input and output. We have additional hardware to translate between PCM/CAIS and Ethernet to help protect existing hardware investment.
Curtiss-Wright has participated in the TmNS program by developing leading-edge technology and has a range of hardware and tools for complete network monitoring and control to bring TmNS into programs today.
