100Mbps Single-Mode Optical Module Design
A 100Mbps single-mode SFP module typically operates at 1310nm wavelength, uses an LC connector, supports link distances up to 10 km, and is hot-swappable for Fast Ethernet ports.
Key Specifications
Wavelength and Fiber Type: Most 100Mbps single-mode SFP modules operate at a 1310nm wavelength over single-mode fiber (SMF), providing long-distance connectivity up to 10 km via LC connectors (FS SFP-100LX-31-I) . Connector Type: Standard modules use LC duplex connectors, ensuring compatibility with most single-mode fiber cabling infrastructures . Data Rate: Supports 100Mbps Fast Ethernet (100BASE-FX) and is compatible with dual-rate Fast/Gigabit Ethernet ports on switches and routers . Hot-Swappable: Modules are hot-swappable, allowing installation or replacement without powering down the network device, which is critical for minimizing downtime . Digital Diagnostic Monitoring (DDM): Many modules support DDM, providing real-time monitoring of optical output power, input power, temperature, and voltage for network management . Power Consumption: Typically low, around ≤1W, suitable for both indoor and industrial deployments . Standards Compliance: Compliant with IEEE 802.3u 100BASE-FX standards and MSA (Multi-Source Agreement) for SFP modules, ensuring interoperability across different vendors . Industrial and Enterprise Use: Certain models are rated for industrial temperature ranges and are suitable for outdoor or harsh environments, while standard modules are optimized for enterprise LAN, SAN, and ISP networks . Interoperability: Certified to work with major network equipment brands such as Cisco, Arista, Juniper, and Brocade, ensuring reliable performance across heterogeneous networks .
Summary
A 100Mbps single-mode SFP module provides reliable, long-distance fiber connectivity with low power consumption, hot-swappable design, and compliance with IEEE 100BASE-FX standards. It is ideal for enterprise, ISP, and industrial applications requiring up to 10 km link distances over single-mode fiber using LC connectors, with optional DDM support for network monitoring .
