Huawei 10G optical module output optical power

Huawei 10G SFP+ optical modules, such as the SFP-10G-LR, operate at 1310nm over single-mode fiber with transmit optical power typically ranging from -8 dBm to -3 dBm and receive sensitivity around -11 dBm, supporting distances up to 10 km.

Key Specifications

Wavelength and Fiber Type: Huawei 10G-LR modules use a 1310 nm wavelength and are designed for single-mode fiber (SMF) applications, supporting duplex LC connectors . Data Rate and Distance: These modules support 10.3125 Gbps (10GBASE-LR) or 9.953 Gbps (10GBASE-LW) data rates, with a maximum transmission distance of 10 km over SMF . Optical Power:

• Transmit Power (Tx): Typically ranges from -8 dBm to -3 dBm
• Receive Sensitivity (Rx): Approximately -11 dBm
• Optical Budget: Around 6 dB, ensuring reliable signal transmission over the specified distance . Digital Diagnostic Monitoring (DDM/DDMI): Huawei 10G modules support real-time monitoring of transmit optical power, received optical power, temperature, laser bias current, and supply voltage via a 2-wire interface (I2C/TWI), allowing network administrators to track module performance and detect potential issues . Compliance and Safety: These modules comply with SFP+ Multi-Source Agreement (MSA) standards SFF-8431, SFF-8432, IEEE 802.3ae 10GBASE-LR/LW, and are Class 1 laser products, meeting IEC-60825 and FDA/CDRH safety standards . Additional Notes:
• Single-fiber bidirectional (BIDI) modules must be used in pairs with complementary wavelengths (e.g., 1270 nm and 1330 nm) for proper operation .
• Modules are factory pre-programmed for compatibility with Huawei switches, routers, NICs, and media converters, ensuring plug-and-play operation . These specifications make Huawei 10G optical modules suitable for data center interconnects, enterprise networks, and high-speed backbone links, providing reliable 10Gbps connectivity with real-time optical power monitoring.
