10 Gigabit Fiber Single-Mode Single-Fiber Module

A 10 Gigabit Single-Mode Single-Fiber Module enables high-speed 10GbE data transmission over long distances using a single strand of single-mode fiber.

Core Function

The primary function of a 10G single-mode SFP+ module is to provide 10 Gigabit Ethernet connectivity over single-mode fiber (SMF) for distances up to 10 kilometers. It converts electrical signals from a network switch or router into optical signals for transmission over fiber and then back into electrical signals at the receiving end, enabling high-speed, long-distance communication between network devices .

Key Features

• Data Rate: Supports up to 10.3 Gbps, suitable for 10GbE networks .
• Wavelength: Operates at 1310 nm, optimized for single-mode fiber transmission .
• Fiber Type: Uses single-mode fiber (SMF, 9/125 µm, G.652 compliant); multimode fiber is not compatible for long-distance links .
• Connector Type: Typically uses LC duplex connectors for transmit and receive paths .
• Hot-Pluggable: Can be installed or replaced without powering down the network device .
• Digital Diagnostic Monitoring (DDM/DOM): Provides real-time monitoring of optical power, temperature, and voltage for network maintenance .
• Single-Fiber Operation: Some modules, like the SFP-10G-BXD/BXU series, use wavelength-division multiplexing (WDM) to transmit and receive over a single fiber strand, effectively doubling fiber efficiency .

Typical Applications

• Enterprise Networks: Connecting switches and routers across buildings or campus backbones.
• Data Centers: High-speed interconnects between servers, storage, and aggregation switches.
• Metro and Carrier Networks: Long-distance 10GbE links for service provider transport.
• Backbone Links: Extending network reach without signal degradation over distances up to 10 km .

Deployment Considerations

• Ensure fiber quality with low attenuation (typically 0.35 dB/km at 1310 nm).
• Maintain proper bend radius to avoid micro-bending losses.
• Verify polarity alignment for LC duplex connectors to maintain correct transmit/receive paths.
• Check optical power budget to ensure reliable signal transmission over the intended distance . In summary, a 10 Gigabit Single-Mode Single-Fiber Module is a high-performance transceiver that extends 10GbE network connectivity over long distances using single-mode fiber, providing reliable, high-speed data transmission for enterprise, data center, and carrier networks.
