10G Single-Mode Huawei Optical Module

Huawei 10G single-mode optical modules, such as SFP-10G-LR and BIDI variants, support long-distance 10G transmission over single-mode fiber with wavelengths typically at 1270–1330nm or 1310nm, offering ranges up to 10km.

Key Types and Specifications

1. SFP-10G-LR

• Wavelength: 1310nm
• Transmission Distance: Up to 10km over single-mode fiber
• Standard: 10GBASE-LR
• Connector: LC duplex
• Use Case: Ideal for enterprise networks and data centers requiring reliable long-range 10G connectivity
• Compatibility: Can operate in multi-vendor environments, but verification is recommended for non-Huawei devices 2. Single-Fiber Bidirectional (BIDI) Modules
• Examples: SFP-10G-BXU1 (TX1270nm/RX1330nm) paired with SFP-10G-BXD1 (TX1330nm/RX1270nm)
• Transmission Distance: Typically 10km
• Usage: Must be used in pairs to enable bidirectional communication over a single fiber strand
• Connector: LC
• Advantages: Reduces fiber cabling requirements while maintaining 10G speeds

Certification and Compatibility

• Huawei recommends using certified optical modules to ensure transmission reliability and service stability. Non-certified modules may cause link instability or compatibility issues .
• Certified modules are labeled with "HUAWEI" and have a manufacturing date after January 1, 2016, with software version V200R008 or later .
• Accessories such as LC duplex fiber cables and SFP+ port converters are compatible with these modules .

Practical Considerations

• Distance Limitations: Even if a module is rated for 40km (e.g., 10G-ER), mismatched specifications like wavelength or receiver sensitivity can reduce effective distance to 20km .
• Multi-Vendor Use: While modules like SFP-10G-LR can work with other brands, always verify compatibility to avoid network issues .
• Installation: Ensure proper pairing for BIDI modules and use certified modules for Huawei switches to maintain optimal performance . Huawei 10G single-mode optical modules provide flexible, high-performance solutions for long-distance 10G connectivity, with options for standard duplex or single-fiber BIDI configurations, suitable for enterprise and data center networks.
