What This Solves

Long-Distance Campus Interconnects

Many organizations operate across multiple buildings or a sprawling campus, requiring reliable high-speed links between locations. This SFP module enables Gigabit Ethernet connectivity over single-mode fiber up to 20 km, ensuring consistent data transfer for critical applications across extended distances.

University campuses, corporate headquarters, large industrial complexes, government facilities

Industrial Environment Networking

Deploying network infrastructure in factories, warehouses, or outdoor cabinets exposes equipment to extreme temperatures and harsh conditions. The module's industrial operating temperature range (-40 °C to 85 °C) ensures stable network performance and uptime in challenging environments where standard modules would fail.

Manufacturing plants, logistics centers, smart city infrastructure, utility substations

High-Availability Network Backbones

Maintaining continuous network operation is paramount for business continuity, especially for core network backbones. Its hot-swappable design allows for module replacement without service interruption, while Digital Diagnostic Monitoring (DDM) provides proactive health insights, reducing the risk of unexpected downtime.

Data center operators, co-location facilities, enterprise infrastructure teams, network operations centers
