Huawei 1310 optical module parameters

The Huawei SFP-10G-ER-1310 is a 10G SFP+ single-mode optical transceiver operating at 1310 nm, designed for long-reach links up to 40 km under standard conditions.Key SpecificationsData Rate: Supports 10 Gigabit Ethernet (10GE)Wavelength: 1310 nmMaximum Transmission Distance: Up to 40 km over single-mode fiber (SMF) under standard conditions; when connected to a 10GBASE-ER module (1550 nm), the distance is limited to 20 km due to wavelength and receiver sensitivity differences Fiber Type: Single-mode fiber (SMF)Connector Type: LC duplexCompatibility: Requires switches running V200R010C00 or later versions Optical Power and Sensitivity: Specific transmit power and receiver sensitivity are not detailed in the sources, but typical 10G ER modules operate with a transmit power range around -3 to +3 dBm and receiver sensitivity near -15 dBmUse Case: Suitable for long-distance backbone links, data center uplinks, and campus interconnects where 10G single-mode fiber is deployedOperational NotesInteroperability: The module must be paired with compatible optical modules; mismatched wavelengths (e.g., 1310 nm vs 1550 nm) reduce the effective transmission distance BIDI Modules: Single-fiber bidirectional (BIDI) modules must be used in pairs, such as SFP-10G-ER-SM1270-BIDI with SFP-10G-ER-SM1330-BIDI Environmental Range: Standard operating temperature is typically 0°C to 70°C for Huawei SFP+ modules, ensuring reliable performance in data center and campus environments This module is ideal for long-reach 10G Ethernet connections where stable performance over single-mode fiber is required, particularly in backbone, metro, and inter-building links. It provides a cost-effective solution for extending 10G networks without extensive fiber upgrades.
