Gigabit Single-Mode Fiber Module

Gigabit Single-Mode Fiber Modules typically operate at 1310nm wavelength, support distances up to 10 km, use LC connectors, and include digital optical monitoring for real-time performance tracking.

Key Specifications

Wavelength and Connector: Most Gigabit single-mode SFP modules operate at a 1310nm wavelength and use LC connectors for fiber connections, ensuring compatibility with standard single-mode fiber (SMF) networks . Transmission Distance: Standard modules support distances up to 10 km, suitable for enterprise LANs, industrial networks, and long-reach fiber links . Some industrial-grade modules may extend beyond this range depending on the model. Data Rate: These modules are designed for 1 Gbps (Gigabit Ethernet) applications, providing reliable high-speed data transmission over single-mode fiber . Form Factor: They use the Small Form-Factor Pluggable (SFP) design, which is hot-swappable and compact, allowing easy installation and replacement without powering down network equipment . Operating Temperature: Industrial-grade modules often support extreme temperatures from -40°C to 85°C, making them suitable for harsh environments . Digital Optical Monitoring (DOM): Many modules include DOM/DDM functionality, enabling real-time monitoring of optical output power, input power, temperature, laser bias current, and supply voltage, which helps maintain network reliability and performance . Compatibility: These SFP modules are MSA-compliant, ensuring interoperability with a wide range of network switches and routers from vendors such as Cisco, Ubiquiti, Intellinet, TP-Link, D-Link, and others . Power Consumption and EMI Protection: Modules are designed for low power consumption, minimal electromagnetic interference (EMI), and excellent electrostatic discharge (ESD) protection, making them suitable for enterprise and industrial deployments . Special Features: Some modules, like Cisco GLC-BX40-D-I, support single-strand bidirectional transmission by using different wavelengths for upstream and downstream signals, enabling efficient fiber utilization over long distances .

Summary

Gigabit Single-Mode Fiber Modules provide high-speed, long-distance connectivity with robust industrial-grade options, hot-swappable SFP form factor, and advanced monitoring features. They are ideal for enterprise networks, industrial environments, and FTTx applications, offering flexibility, reliability, and compliance with industry standards .
