• IEEE 802.3z compliance guarantees layer 1 interoperability with any standards-compliant gigabit Ethernet switch, router, or media converter using SFP slots
• 1000BASE-EX extended reach specification uses higher transmit power and improved receiver sensitivity compared to 1000BASE-LX, enabling 40km links where standard LX modules reach only 10km
• Industrial operating temperature from -40 to 85 degrees C makes this suitable for outdoor cabinets, railway wayside equipment, substation automation, and mining operations where commercial-grade optics would fail
• SFF-8472 DDM functionality exposes transmit power, receive power, temperature, supply voltage, and laser bias current via I2C interface for proactive link monitoring and troubleshooting
• Single-mode fiber at 1310nm wavelength avoids chromatic dispersion penalties seen at 1550nm over intermediate distances, and provides lower cost than CWDM or DWDM solutions for point-to-point links
• Hot-swappable design allows installation or replacement while the host switch remains powered, minimizing network downtime during maintenance windows
• 1.25 Gbps line rate with 8b/10b encoding delivers 1000 Mbps effective throughput for full gigabit Ethernet bandwidth on fiber infrastructure
