networkcommunicationflange

Parallel optical devices are key components for realizing high-speed and large-capacity optical communication. They are used inside high-speed optical modules supporting transmission rates of 400G, 800G, and 1.6T, and are compatible with various module types. The MT-FAU (Multi-Fiber Termination Fiber Array Unit) used in optical modules is a high-precision fiber array, in which 4 or 8 fibers are arranged with fixed spacing (e.g., 750 μm or 127 μm) in a V-groove substrate. The channel spacing accuracy can be controlled within 0.5 μm. The fiber array end face is ground and polished to form either a flat or angled surface (e.g., 8°, 42.5°) to achieve low-loss coupling with other optical components inside the module. The MT ferrule serves as the external optical interface of the module, with PC (0°) or APC (8°) end-face polishing options to ensure stable external optical transmission. This product is mainly used in high-speed optical modules (such as QSFP-DD, OSFP, and QSFP112 multi-channel modules) and in CPO (Co-Packaged Optics) applications for direct coupling with silicon photonic chips, achieving high-bandwidth interconnections. - MT-FAU is widely used in telecommunications, data communication, medical technology, security, and sensing fields, with strong market potential for future growth. Features - Parallel Transmission and Coupling - High Precision and Reliability - High Density and Compact Design - Cost Efficiency Specific polishing angles enable total internal reflection at the fiber end face. Combined with low-loss MT ferrules, the MT-FAU provides compact and efficient parallel optical interconnection solutions for 400G/800G/1.6T multi-channel optical modules, especially suitable for high-load, long-duration data transmission scenarios in AI training data centers. With high-precision manufacturing and low insertion loss, MT-FAU ensures excellent channel uniformity and stable optical transmission, meeting the stringent data transmission quality requirements of AI computing networks. Its compact form factor fits the trend toward higher integration in optical modules, saving space and supporting high-density connections required by modern data centers. The high integration and transmission efficiency of MT-FAU help reduce overall system cabling complexity. In large-scale deployments, it enables high performance while minimizing maintenance costs during long-term module operation.
