Why choose it

This module combines low power draw with DDM for real-time monitoring of optical parameters, enabling proactive maintenance. Its MSA compliance ensures compatibility with a wide range of networking equipment, reducing sparing complexity. The 1310 nm wavelength and FP laser provide stable performance over long distances, while the LC duplex connector offers secure, high-density connections.

Ideal use cases

• Interconnecting switches in campus or enterprise LANs
• Extending networks between buildings up to 20 km apart
• Gigabit Ethernet uplinks for service provider access
• Fiber Channel over Ethernet (FCoE) applications
• Upgrading existing 1000BASE-SX links to longer reach

Good to know

The transceiver operates within a commercial temperature range (0°C to 70°C), making it suitable for standard data center and wiring closet environments. It is fully hot-swappable, allowing installation or replacement without network downtime. For optimal performance, use with single-mode fiber (9/125 µm) and ensure both ends match wavelength and standard.
