10 Gigabit Single-Mode Fiber Interface 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.
