    What are the uses of low-speed optical modules

    High-rate optical modules are suitable for scenarios that require large amounts of data processing and high-performance computing, while low-rate optical modules are suitable for scenarios such as short-distance communications and internal data center communications. Typically, modules with a transmission rate of 1 Gbps or lower are classified as low-speed optical modules. Categories Currently, low-speed optical modules mainly come in two form factors: GBIC and SFP, which differ in size, physical design, and practical application. From hyperscale cloud platforms to enterprise backbones and next-gen telecom networks, optical transceiver modules play a mission-critical role in modern connectivity infrastructure. Its primary function is to achieve optoelectronic conversion by converting electrical signals into optical signals and vice versa.
