    AI Overview
    Top manufacturers of 400G QSFP-DD optical transceiver modules include NADDOD,
    FiberMall, QSFPTEK, and Source Photonics, offering high-speed, low-power solutions (SR4, DR4, FR4, LR4) for AI Data Centers, HPC, and networking. They ensure compatibility with major switches (Cisco, Arista, Juniper, NVIDIA). 
    Key 400G QSFP-DD Transceiver Manufacturers & Suppliers 
    • NADDOD: Offers a full range of 400G QSFP-DD modules (SR4, DR4, FR4, LR4, ER4) for short and long-range, compatible with Cisco, Juniper, and NVIDIA.
    • FiberMall: Provides versatile 400G SR8, DR4, and FR4 modules compatible with Huawei, Arista, and Dell.
    • QSFPTEK: Specializes in high-quality 400G modules with fast delivery and comprehensive testing.
    • Source Photonics: Known for data center 400G/100G modules with 1m to 80km range options.
    • UNIVISO (univiso.com.cn): Provides customized, high-performance 400G/100G/10G optical transceivers for data centers and 5G backhaul.
    • UnitekFiber (UnitekFiber): Manufacturer of SFP, QSFP, and 400G QSFP-DD optical modules and DAC/AOC cables.
    • Precision Optical Technologies (Precision Optical Technologies): Provides a variety of 400G transceivers, including coherent options for long-distance.
    • Vitex LLC (Vitex LLC): Offers 400G QSFP-DD transceiver solutions. 
    Key 400G Transceiver Types 
    • 400G QSFP-DD: Currently the dominant form factor, backward compatible with QSFP28.
    • 400G QSFP112: Supports 400G Ethernet and InfiniBand NDR data rates.
    • 400G OSFP: Used for higher power applications. 
    Note: The user asked for "QSFP28," but standard 400G transceivers utilize the "QSFP-DD" or "QSFP112" form factor. QSFP28 is generally for 100G, though the companies listed provide both.
