Modules of the Fiberhome SR4

Fiberhome SR4 modules are 400G short-reach optical transceivers using four parallel channels over multimode fiber, designed for high-speed data center connectivity.OverviewFiberhome SR4 modules are part of the 400G optical transceiver family, optimized for short-reach (SR) applications in data centers. The "SR" denotes Short Reach, and the "4" indicates the use of four parallel optical channels, each capable of transmitting 100 Gbps, for a total of 400 Gbps bandwidth . These modules are ideal for high-density, high-speed connections in cloud computing, AI, and HPC environments .Key FeaturesData Rate: 400 Gbps aggregate, with 100 Gbps per lane using PAM4 modulation .Fiber Type: Multimode fiber (MMF), typically OM3 or OM4, with OM4 supporting distances up to 100 meters .Wavelength: 850 nm VCSEL laser array for each channel .Connector: MPO-12 interface, which consolidates all four lanes into a single plug for simplified patching .Form Factors: Available in QSFP-DD, QSFP112, and OSFP to accommodate different network hardware and thermal requirements .Transmission Method: Parallel optics, transmitting data simultaneously across four fiber pairs .Breakout Capability: Can often be split into four 100G channels for flexible network configurations .ApplicationsFiberhome SR4 modules are widely used in data center interconnects, high-performance computing clusters, and AI workloads, where short-distance, high-bandwidth connections are critical . They provide a cost-effective and efficient solution for dense network environments, supporting rapid deployment and scalability.Deployment ConsiderationsDistance: OM3 fiber supports up to ~70 meters, while OM4 fiber extends reach to 100 meters .Power Consumption: Typically lower than long-range modules, which helps in dense port deployments and thermal management .Compatibility: Works with standard 400G SR4 interfaces and can interoperate with other 400G modules in breakout mode . Fiberhome SR4 modules combine high-speed performance, compact form factor, and parallel optics technology, making them a standard choice for modern data center short-reach applications.
