Huawei Multimode 100Mbps Optical Module

Huawei 100Mbps multimode optical modules are primarily SFP transceivers designed for Fast Ethernet, supporting multimode fiber with distances up to 2 km, and often require BIDI pairing for single-fiber applications.Common Models and TypesHuawei offers several 100Mbps SFP optical modules for multimode fiber, typically under the Fast Ethernet (FE) category :SFP-FE-SX-MM: Standard 100Mbps multimode SFP module, operating at 850nm wavelength, designed for distances up to 550 meters over OM2 multimode fiber.SFP-FE-LX-MM: Long-wavelength multimode module, often used for distances up to 2 km over OM3 multimode fiber.BIDI Modules: Single-fiber bidirectional modules, such as SFP-FE-LX-SM1310-BIDI paired with SFP-FE-LX-SM1550-BIDI, allow simultaneous transmit and receive over a single fiber strand .Key FeaturesConnector Type: Typically LC connectors for multimode fiber.Wavelength: 850nm for standard multimode modules; BIDI modules use paired wavelengths (e.g., 1310nm/1550nm).Distance Support: Standard multimode SFPs support 550m–2 km depending on fiber type (OM2, OM3, OM4).Temperature Range: Commercial modules operate from 0°C to 70°C.Diagnostics: Many modules support DDM/DOM for real-time monitoring of optical power, temperature, and voltage.Usage NotesBIDI Pairing: Single-fiber BIDI modules must always be used in complementary pairs to function correctly .Compatibility: Huawei 100Mbps multimode SFPs are compatible with Huawei switches and routers that support Fast Ethernet SFP slots.Applications: Ideal for enterprise LANs, campus networks, and short-distance fiber links where multimode fiber is deployed.
