　　Product Positioning and Core Features

　　Brand and Series: This reflective memory (RFM) real-time optical network module, part of the Panametrics/VMIC series from General Electric (GE), is designed for industrial automation, real-time control systems, and high-reliability scenarios. Designed for harsh industrial environments, it supports high-speed data sharing, low-latency communication, and multi-node real-time interaction. It is widely used in industrial control, real-time simulation, transportation systems, energy management, and other fields.

　　Core Technology: Based on a fiber-optic reflective memory architecture, it implements a "single-point write, multiple-point simultaneous update" data sharing model, eliminating CPU involvement in transmission and ensuring low latency (nanoseconds) and high determinism.

　　Key Parameters:

　　Memory Capacity: Onboard 128MB/256MB SDRAM with parity checking to ensure data integrity.

　　Transmission Performance: Serial rate 2.12 Gbaud, transmission bandwidth 43MB/s to 174MB/s (dynamic data packets 4-64 bytes), supporting networking of 256 independent nodes.

　　Transmission Distance: 300 meters over multimode fiber, 10 kilometers over single-mode fiber, suitable for long-distance industrial scenarios.

　　Interfaces and Compatibility: Supports bus standards such as PCI, PMC, and PCIe, and is compatible with operating systems such as Windows, Linux, and VxWorks, adapting to a variety of hardware platforms.

　　High-Speed Transmission Capability

　　Fiber Network Rate: Supports 2.12 Gbaud serial rate, with a maximum transmission rate of 174 MB/s (64-byte data packets).

　　Low Latency: Inter-node transmission latency is in the hundreds of nanoseconds, and a 30-node system requires only 30 microseconds for full network transmission.

　　Multi-Node Support: Connects up to 256 nodes. When data is written to the memory of any node, it is automatically synchronized to the memory of all nodes.

　　Hardware Specifications

　　Memory Capacity: Onboard 128MB or 256MB SDRAM, supporting dynamic packet sizes (4-64 bytes).

　　Interfaces and Buses: Compatible with PCI, PMC, VME, and other bus interfaces, supports 3.3V/5V voltage levels, and is compatible with various operating systems (Windows, Linux, VxWorks, etc.).

　　Transmission Distance: Up to 300 meters with multimode fiber and up to 10 kilometers with single-mode fiber. Redundant transmission modes are supported for enhanced reliability.

　　Technical Advantages

　　No CPU Overhead: Data transmission is automatically handled by hardware, requiring no CPU intervention, reducing system load.

　　Error Detection and Redundancy: Built-in error detection mechanisms and redundant transmission modes ensure data integrity.

　　Cross-platform compatibility: Supports PCI 64-bit 66MHz transmission and is compatible with various bus architectures (such as PCIe and CPCI) and operating systems.

　　Expandability:

　　Supports PCIe x16/x8 expansion slots and is compatible with operating systems such as Windows, Linux, and VxWorks.

　　Remote interconnection between multiple laboratories and equipment can be achieved through a fiber optic hub, supporting network segmentation and rapid isolation of faulty nodes.

　　Technical Highlights and Innovations

　　Deterministic Transmission: Utilizing a dual-channel reflective memory architecture, inter-node transmission latency is less than 400 nanoseconds. It supports a priority scheduling algorithm and intelligent arbitration mechanism to ensure that critical instructions are transmitted first.

　　Redundancy and Reliability: Optional redundant transmission mode, built-in error detection and dynamic bandwidth allocation, and hot-swappable support ensure uninterrupted system maintenance.

　　Expandability: Supports ring and star topologies and is compatible with multimode and single-mode fiber to accommodate diverse network scale requirements. A standard C language API and real-time data verification toolkit are provided, supporting custom CRC checks.

　　Environmental Adaptability: Operating temperature range of -40°C to 85°C, vibration resistance (MIL-STD-810G), and IP40 protection, suitable for harsh industrial environments.

　　Application Scenarios and Industry Value

　　Industrial Automation: Factory automation control systems, equipment monitoring, and data acquisition improve production efficiency and responsiveness.

　　Traffic Control: Intelligent Transportation Systems (ITS) and traffic signal control enable real-time data synchronization and decision-making.

　　Energy Management: Power monitoring and energy management systems optimize energy distribution and real-time monitoring.

　　Medical Equipment: Medical imaging equipment and patient monitoring systems provide stable computing and storage support.

　　Aerospace and Scientific Research: Flight simulators, nuclear fusion devices, and particle collider experiments meet the needs of high-precision timing control.

　　Other Applications: Financial transactions, distributed system communications, real-time data processing, and other fields requiring extremely low latency and high reliability.

　　Installation and Maintenance Support

　　Installation and Configuration: Supports standard fiber optic connections (LC interface), provides driver installation guides and API integration documentation, and is compatible with multiple operating systems and hardware platforms.
