Huawei Server Optical Module Multimode

Huawei multimode optical modules, such as the eSFP-GE-SX-MM850, support short-distance, high-speed data transmission over multimode fiber with 850 nm wavelength and SFP form factor.OverviewHuawei multimode optical modules are designed for short-distance, high-speed connections in data centers and server environments. They are compatible with multimode fibers (OM2/OM3/OM4) and typically operate at 850 nm wavelength. These modules are available in various form factors, including SFP, SFP+, and eSFP, supporting data rates from 1.25 Gbps (Gigabit Ethernet) up to 25 Gbps depending on the module type .Key FeaturesForm Factor: SFP/eSFP, hot-swappable, compact design for server and switch ports .Transmission Rate: 1.25 Gbps for Gigabit modules; higher rates available in SFP+ or SFP28 variants .Wavelength: 850 nm for multimode fiber, suitable for short-distance links up to 550 meters on OM2 fiber .Interface Type: LC Duplex connectors, compliant with SFP MSA and IEEE 802.3z standards .Diagnostics: Support for Digital Optical Monitoring (DOM/DDM) to monitor voltage, temperature, transmit and receive optical power .Reliability: Metal casing for EMI protection, low insertion loss, and compliance with ROHS standards .ApplicationsServer Interconnects: Connecting servers to switches in data centers.Short-Distance Data Center Links: Ideal for intra-rack or inter-rack connections where multimode fiber is deployed.Switch Compatibility: Compatible with Huawei S5700 and S5720 series switches, among others .Multimode vs Single-ModeMultimode Modules: Lower cost, shorter distance, suitable for small-capacity links.Single-Mode Modules: Higher cost, longer distance, suitable for backbone or long-distance connections .Certification and CompatibilityHuawei recommends using certified optical modules to ensure reliability and service stability. Certified modules are labeled with "HUAWEI" and verified through commands like display transceiver or display elabel on Huawei switches . Non-certified modules may cause link instability or reduced performance.SummaryHuawei multimode optical modules provide cost-effective, reliable, and high-speed connectivity for servers and data center networks. They are optimized for short-distance multimode fiber links, support diagnostic monitoring, and are compatible with a wide range of Huawei switches and server interfaces, making them suitable for modern AI and enterprise data center environments .
