Huawei 10G SFP+ optical modules support single-mode fiber with dual-core bidirectional operation up to 20km.

Key Specifications

• Transmission Standard: 10GBase-BX SFP+
• Fiber Type: Single-mode fiber (SMF)
• Maximum Distance: 20 km over SMF
• Wavelengths: 1270nm transmit / 1330nm receive (bidirectional)
• Connector Type: LC duplex
• Bidirectional Operation: Must be paired with a complementary module of opposite wavelength (e.g., 1270nmTx/1330nmRx with 1330nmTx/1270nmRx) to function correctly

Compatibility and Standards

These modules are Huawei-compatible and comply with Multi-Source Agreement (MSA) standards, ensuring seamless integration with Huawei switches and other network devices . They are designed to meet or exceed OEM specifications and are fully tested for data traffic and application performance.

Environmental and Operational Features

• Operating Temperature: -40°C to 85°C
• Storage Temperature: -40°C to 85°C
• Durability: Built to withstand harsh environments and maintain stable performance

Usage Notes

• Pairing Requirement: Single-fiber bidirectional modules must always be used in pairs with complementary wavelengths to achieve the full 20 km range .
• Applications: Ideal for long-distance 10G network links, data centers, and enterprise backbone connections.
• DOM Support: Some modules include Digital Optical Monitoring (DOM) for real-time monitoring of optical parameters .

Summary

The Huawei 10G SFP+ single-mode dual-core optical module is a reliable solution for 20 km high-speed connections over single-mode fiber. Its bidirectional design, wide operating temperature range, and MSA compliance make it suitable for enterprise and carrier-grade networks, provided it is paired correctly with a complementary module.
