    AI Overview
    Top 400G FR4 optical module manufacturers include industry leaders like
    Coherent (formerly II-VI) and specialized providers such as Fiberstamp, Fibertop, and Dromeda Networks. These modules, often in QSFP-DD or OSFP formats, support 400Gbps transmission up to 2km over duplex single-mode fiber (SMF) using CWDM4 technology. 
    Key 400G FR4 Module Manufacturers and Suppliers 
    • Coherent: Known for producing 400G-FR4 Gen 3 QSFP-DD transceivers.
    • FIBERSTAMP: Offers 400G OSFP-RHS FR4 2km EML modules.
    • Fibertop: Specializes in 400G FR4 modules.
    • Dromeda Networks: Provides 400G OSFP FR4 transceivers.
    • FS.com: Supplies compatible 400GBASE-FR4 QSFP-DD modules.
    • Intel: Manufactures silicon photonics-based 400G FR4 modules.
    • FluxLight: Supplies third-party compatible 400G FR4 transceivers. 
    Product Specifications and Features 
    • Data Rate: 400 Gbps (via
      4×1004 cross 100
      4×100
       Gbps PAM4).
    • Form Factors: QSFP-DD, OSFP.
    • Reach: 2 km over Single-Mode Fiber (SMF).
    • Connector: Duplex LC.
    • Power Consumption: Typically
      ≤9is less than or equal to 9
      ≤9
       W.       
    These, along with manufacturers like FiberMall, supply high-density data center interconnects.
