Technical Principle

The 100G QSFP28 AOC operates on the principle of optical communication. It uses an 850nm VCSEL laser as the core transmitting device to convert electrical signals into optical signals, which are then transmitted through OM3 or OM4 multimode optical cables. At the receiving end, the optical signals are converted back into electrical signals, completing the high-speed data transmission process. The product is rigorously designed in accordance with the SFF-8431 protocol for its electrical interface, ensuring compatibility with various network devices and stable signal transmission. Its low-power design optimizes circuitry and light-source driving methods to reduce energy consumption during operation, while its EMI-resistant design employs shielding structures and signal optimization to minimize electromagnetic interference, thereby guaranteeing accurate and stable data transmission. The hot-swappable feature is enabled by a dedicated interface design, allowing components to be installed or replaced without powering down the system, thus facilitating maintenance or upgrades and enhancing network system availability.
