(Further details are provided in the following sections). This comprehensive approach ensures the reliability and stability of the modules in real-world applications.
The Key Items of FS InfiniBand Transceivers Test
Scenario Application Test
The FS Testing Center utilizes a full range of NVIDIA/Mellanox InfiniBand NDR/HDR/EDR switches and NICs to set up network topologies identical to real-world applications, in order to simulate customers' actual usage scenarios. Each InfiniBand transceiver undergoes compatibility and full-load transmission testing to ensure seamless integration and reliable performance in real-world application environments.
1. Compatibility Testing
This test focuses on detecting alarms when modules are connected to host devices, verifying normal connectivity and functionality, and ensuring accurate DDM (Digital Diagnostic Monitoring) information along with correct module type display. These measures guarantee plug-and-play compatibility with NVIDIA/Mellanox devices, enabling seamless integration without additional configuration or troubleshooting.
2. Full-Load Transmission Testing
Full-load testing assesses stable connectivity, measures error rates to identify potential performance issues, and evaluates traffic conditions under high-stress scenarios. This ensures the modules deliver reliable and efficient performance, reducing the risk of downtime or errors and supporting uninterrupted operations even under heavy network loads.
This method of real-world testing ensures that our product delivers excellent performance in high-bandwidth, low-latency network environments and achieves 100% compatibility with the original NVIDIA/Mellanox InfiniBand.

Performance and Reliability Test
In addition to being 100% tested by original NVIDIA/Mellanox InfiniBand for quality and compatibility, FS also ensures high-quality, reliable optical components through advanced manufacturing processes and world-class testing equipment.
1. Performance Testing
Performance testing of transceivers involves a comprehensive evaluation to ensure signal quality, stability, and reliability in various network scenarios. Key tests include power and wavelength measurements to verify signal strength and consistency from transmitter to receiver, traffic tests to minimize bit error and packet loss rates, and optical performance assessments to evaluate eye diagrams, receiving sensitivity, extinction ratios, and operational parameters like current and voltage. Additionally, end-face inspections ensure cleanliness for stable data transmission and extended durability. In short, FS deeply evaluates module performance in various scenarios by simulating normal, peak, and abnormal load conditions, ensuring stability under high-intensity network demands.
2. Reliability Testing
Reliability testing is conducted to ensure transceivers perform consistently and durably in challenging environments. This includes temperature stress tests to verify functionality under extreme conditions, anti-static performance tests to assess resistance to external electrostatic discharge (ESD), and mechanical shock and vibration tests to simulate harsh transportation and deployment scenarios. These evaluations enhance product reliability by reducing the risk of damage during shipping and installation, ensuring long-term durability, and supporting stable performance in diverse settings, from outdoor base stations to data centers.
The comprehensive performance and reliability testing underscores FS's relentless pursuit of product quality. Every module not only meets industry standards but also passes multiple layers of rigorous validation before leaving the factory, providing customers with stable, high-performance network solutions.
