Transceiver SFP EXSYS EX-SFP-2000 LC Singlemode Duplex 20km - 1,25 Gbit/s

The EXSYS EX-SFP-2000 stands out as a dependable SFP transceiver engineered for long-distance gigabit links. Unlike generic modules that often compromise on stability, this unit delivers a full 20 km reach over single-mode fiber with a 1310 nm FP laser, ensuring your data travels farther without repeaters. It is MSA compliant, so it drops into any standard SFP port across major switch and router brands, making it a versatile spare or upgrade for enterprise and campus networks.

Highlights

• Hot-swappable SFP form factor for zero-downtime installation
• Duplex LC connector for standard single-mode patch cables
• Digital Diagnostic Monitoring (DDM/DOM) for real-time health checks
• Supports Gigabit Ethernet (1000BASE-LX/LH) per IEEE 802.3z
• Wide operating temperature range: 0°C to 70°C

In daily use

Deploy the EX-SFP-2000 in backbone links between buildings, across campuses, or in metro Ethernet setups. Its 1.25 Gbps line rate handles typical enterprise traffic with ease, and the duplex design ensures full simultaneous bidirectional communication. The LC connector clicks securely into place, and because the module is hot-swappable, network maintenance becomes a simple plug-and-play task. With DDM support, you can monitor optical power, temperature, and laser bias current via your switch's management interface, catching potential issues before they cause downtime.
