About
The RLT-ETH-x is a series of high-performance Ethernet switches specifically designed for harsh space environments, developed in partnership with TTTech. These switches are engineered to simplify the design of complex distributed systems by enabling the safe processing of both critical and non-critical Ethernet traffic on a single network. They support both synchronized and non-synchronized functions, ensuring that system-critical hard real-time functions benefit from reserved bandwidth, full determinism, and delivery jitter below 1 microsecond. This capability is crucial for maintaining the integrity and reliability of data transfer in demanding space applications. The series offers various models with different port configurations, including up to 4, 12, and 20 Ethernet ports, providing flexibility for different system architectures. Réaltra also works with customers to develop bespoke products based on commercial-off-the-shelf (COTS) and/or rad-tolerant components, indicating a commitment to robust space-grade solutions.
