10g Single-Fiber Optic Module Model

10G single-fiber optic modules (SFP+) enable 10 Gigabit Ethernet connections over a single strand of fiber, often requiring paired modules for bidirectional communication.Key FeaturesForm Factor: SFP+ (Small Form-factor Pluggable Plus), hot-swappable for easy installation without powering down switches or devices .Fiber Type: Typically single-mode fiber (SMF) for long-distance transmission, with duplex LC UPC connectors .Transmission Distance: Standard single-mode modules can support up to 10 km, while bidirectional (BiDi) modules can achieve similar distances using a single fiber strand .Power and Safety: Class 1 laser product; avoid looking directly into the fiber ends when powered .Single-Fiber Bidirectional (BiDi) ModulesFunctionality: BiDi modules allow full-duplex communication over a single fiber using Wavelength Division Multiplexing (WDM), with separate wavelengths for transmitting and receiving signals .Pairing Requirement: BiDi modules must be used in pairs, e.g., SFP-10G-BXD1 with SFP-10G-BXU1, to ensure proper bidirectional communication .Advantages: Reduces fiber usage by 50%, simplifies cabling, and supports high-density deployments .Components: Each module integrates a DFB laser, a PIN photodiode receiver, and an internal WDM coupler for signal separation .Deployment ConsiderationsCompatibility: Ensure modules are compatible with your switch or NIC; many vendors provide certified modules for interoperability .Distance and Fiber Type: Verify the module's maximum link length and fiber type (OM3/OM4 for multimode, SMF for long distances) to match your network infrastructure .Monitoring: Some modules support digital optical monitoring (DOM) for diagnostics and performance tracking .Example ModulesUbiquiti 10G SM SFP+: Supports 10G connections up to 10 km over single-mode fiber with duplex LC UPC connectors .FS 10G BiDi SFP+: Enables full-duplex 10G transmission over a single fiber strand using WDM, with up to 10 km reach .Huawei SFP-10G-BX Series: Single-fiber BiDi modules requiring paired deployment for proper operation . These modules are widely used in data centers, enterprise networks, and service provider environments to optimize fiber usage, reduce cabling complexity, and maintain high-speed connectivity.
