What This Solves

Extending Campus Network Links

Organizations with multiple buildings or large facilities need to connect network segments over distances greater than standard copper cabling allows. This SFP module provides a reliable 1.25 Gbit/s fiber link up to 550 meters, ensuring high-speed data transfer between distributed network closets.

Educational institutions, corporate campuses, manufacturing facilities, large office complexes

Ruggedized Industrial Connectivity

Industrial environments like factories, warehouses, or outdoor installations often expose networking equipment to extreme temperatures. The ISM311LM operates reliably from -40°C to 85°C, maintaining critical network uptime where standard components would fail.

Industrial automation, logistics and distribution centers, smart city infrastructure, outdoor surveillance systems

Proactive Network Health Monitoring

IT operations teams require visibility into network component performance to prevent outages and troubleshoot issues efficiently. Digital Diagnostic Monitoring (DDM) provides real-time data on module status, enabling proactive maintenance and reducing mean time to repair.

Network operations centers, IT infrastructure teams, facilities management, data center operators

Frequently Asked Questions

What type of fiber cable is compatible with the ISM311LM module?

The ISM311LM module is designed for multi-mode fiber (MMF) cables with core/cladding diameters of 50/125 µm or 62.5/125 µm. It utilizes an LC (UPC) fiber optic connector for reliable connections.

Can this SFP module be used with non-TP-Link network switches?

Yes, the ISM311LM is compatible with the Small Form Pluggable Multi-Source Agreement (SFP-MSA) standard. This ensures broad interoperability with a wide range of SFP-compliant networking equipment from various manufacturers.

What is the purpose of Digital Diagnostic Monitoring (DDM) in this module?

DDM provides real-time monitoring of critical SFP parameters such as temperature, transmit/receive power, and voltage. This allows IT administrators to proactively assess link health, identify potential issues, and troubleshoot network problems more efficiently.

Is the ISM311LM suitable for outdoor deployments?

While the module itself has an industrial operating temperature range of -40°C to 85°C, its suitability for outdoor deployment depends on the host device and enclosure. It is designed to withstand harsh environmental conditions when properly housed within industrial-grade equipment.
