The Curtiss-Wright/Systran SCRAMNet GT200 PMC module is a high-speed real-time data communication platform engineered for time-critical applications requiring deterministic, low-latency network infrastructure. Built on the PMC (PCI Mezzanine Card) form factor, it integrates directly into embedded computing systems via standard PMC expansion slots. The module delivers up to 200 MB/s per fiber optic port and supports multiple network topologies—star, ring, and extended star configurations—making it suitable for demanding industrial and defense environments where data integrity and synchronization are mission-critical.
