100m Optical Module Single Mode

A 100M single-mode optical module is a hot-swappable SFP transceiver that supports 100 Mbps Ethernet over single-mode fiber, typically with LC duplex connectors and a reach of up to 10 km.OverviewA 100M single-mode SFP module converts electrical signals into optical signals for transmission over single-mode fiber (SMF), enabling Fast Ethernet connectivity at 100 Mbps. These modules are essential for extending network reach beyond copper cabling limits, providing immunity to electromagnetic interference, and supporting secure, long-distance links .Key SpecificationsData Rate: 100 Mbps (Fast Ethernet)Fiber Type: Single-mode fiber (SMF)Connector: LC duplexWavelength: Typically 1310 nmMaximum Distance: Up to 10 km (6.2 miles) depending on the module and fiber qualityDuplex Mode: Half or full-duplexHot-Swappable: Yes, allowing seamless upgrades or replacements without network downtimeDigital Diagnostic Monitoring (DDM): Supported on many modules to monitor transceiver status via SNMP Power Consumption: Usually less than 1 WUse CasesEnterprise LANs: Connecting switches across buildings or campus networksData Centers: Linking Fast Ethernet ports over long distancesTelecom Networks: Supporting legacy 100 Mbps links or media convertersIndustrial Networks: Reliable long-distance fiber connections in harsh environments Selection ConsiderationsDistance Requirements: Single-mode is preferred for links exceeding 2 km, offering lower signal attenuation and higher bandwidth potential .Compatibility: Ensure the SFP module is MSA-compliant and compatible with your switch or router brand to avoid network issues .Fiber Availability: Standard duplex modules use two fibers (one for Tx, one for Rx), while BiDi modules allow single-fiber operation for fiber-efficient deployments .Wavelength Matching: Confirm the module's wavelength (commonly 1310 nm) matches your network design.Environmental Conditions: Check operating temperature and humidity ranges if deploying in industrial or outdoor settings .Recommended Standards100BASE-LX/LH: Standard for single-mode 100M SFP modules, supporting distances up to 10 km over SMF .MSA Compliance: Ensures interoperability with multiple switch brands and network devices .Practical TipsAlways verify device compatibility before purchase.Use DDM-enabled modules for real-time monitoring of optical power, temperature, and voltage.Consider lifetime warranty and technical support options for long-term reliability . By selecting a 100M single-mode SFP module that matches your network's distance, fiber type, and device compatibility, you can ensure reliable, high-performance Fast Ethernet connectivity over long distances.
