Certified QSFP optical module 200G

200G QSFP optical modules, such as QSFP56 and QSFP-DD, enable high-speed 200 Gigabit Ethernet connectivity with four 50–56Gbps channels, supporting data center, AI, and enterprise networks.Key Features and SpecificationsQSFP56 (Quad Small Form-factor Pluggable 56) modules are designed for 200GbE applications, using four independent channels at 56Gbps each, achieving an aggregate 200Gbps data rate . These modules are hot-pluggable, compact, and support PAM4 modulation, which allows higher data throughput over the same fiber . They are compatible with 200GBASE Ethernet and can also support HDR over 2x InfiniBand, providing flexibility for network upgrades . QSFP-DD (Double Density) modules extend the QSFP form factor to support 8 channels, but can operate in 4-channel QSFP56 mode for 200G applications, offering backward compatibility with QSFP28 and QSFP56 ports . This allows network operators to split a 200G port into multiple lower-speed links, such as 2x100G or 4x50G, depending on the breakout configuration .Optical Technology200G QSFP optical modules use laser arrays to convert electrical signals into optical signals for transmission over fiber . They typically operate at 850nm wavelength for multimode fiber (MMF) and can support distances up to 100 meters on OM4 MMF for 200GBASE-SR4 transceivers . Modules include Forward Error Correction (FEC) and high-performance amplifiers to maintain signal integrity over the transmission path .Use CasesData Centers: High-density spine and leaf layer connections, AI/ML workloads, and high-performance computing networks .Enterprise Networks: Core and distribution layers requiring 200G connectivity .Service Providers: High-bandwidth links for aggregation and backbone networks .Copper and Breakout OptionsFor short-reach connections, QSFP-200-CuxM passive copper cables provide a cost-effective 200G link between adjacent racks or within a rack, available in lengths of 1–3 meters . Breakout cables like QSFP-4S50-CUxM allow a single 200G port to connect to four 50G SFP56 ports, enabling flexible network segmentation .AdvantagesHigh data density: Supports multiple 200G links in a single rack unit.Energy efficiency: Lower power consumption compared to previous generations.Future-proofing: Backward compatibility with QSFP28 and QSFP56 ensures smooth network upgrades.Hot-swappable: Modules can be replaced without downtime, maintaining network availability .Summary200G QSFP optical modules, including QSFP56 and QSFP-DD, provide a high-performance, flexible, and scalable solution for modern high-speed networks. They support multiple breakout configurations, offer both optical and copper options, and are ideal for data centers, enterprise, and service provider networks seeking to optimize bandwidth, density, and operational efficiency .
