SFP-100FX-31-I functions as an industrial-grade 155M SFP multi-mode optical transceiver, pairing a 1310nm FP laser with a PIN photodetector to secure a 2km transmission span throughout a ruggedized -40°C to +85°C operating envelope.
Key Features of Arista Networks SFP-100FX-31-I Compatible LINK-PP 155M SFP
Arista Networks SFP-100FX-31-I Compatible LINK-PP brings reliable fiber connectivity to rugged industrial networks requiring stable short-haul links. This duplex LC transceiver operates over multimode fiber at a 1310nm wavelength to cover a 2km distance. Integrated telemetry features also allow operators to easily track the health of the hardware.
This module strictly follows the standard SFP Multi-Source Agreement (MSA) for hassle-free installation into a wide variety of multi-vendor network switches. It also includes built-in SFF-8472 digital diagnostics functions to deliver internal hardware telemetry. This compliance ensures smooth plug-and-play setup without compatibility worries.
SFP-100FX-31-I: 155 Mbps Connectivity for Fast Ethernet Infrastructure
Operating at a steady 155Mbps, this device is built specifically to maintain data flow across legacy Fast Ethernet systems and industrial automation grids. It handles data traffic smoothly, preventing packet drops in sensitive communication lines. It is a highly efficient choice for factory automation and utility sub-stations.
SFP-100FX-31-I Module with 1310nm Wavelength
By pairing a 1310nm FP laser source with a matching PIN photodetector, the transceiver achieves clean optical signaling. This wavelength choice avoids excessive attenuation on multimode fiber lines, keeping the signal sharp. The result is consistent data transmission over the entire fiber run.
SFP-100FX-31-I Module Supporting 2km Transmission
The transceiver provides an optical power budget perfectly calculated to span distances up to 2km. This reach is ideal for connecting hardware across large warehouse floors, localized corporate campuses, or adjacent facilities. It comfortably fulfills everyday short-distance industrial network requirements.
SFP-100FX-31-I Module with Duplex LC Interface
The physical connection relies on a dual-fiber duplex LC connector that snaps tightly into place to prevent accidental disconnects. This interface layout supports simultaneous two-way traffic for efficient transmission and reception. Its compact design matches standard fiber patch cords perfectly.
SFP-100FX-31-I Module with DOM for Real-Time Monitoring
Featuring Digital Optical Monitoring (DOM), the transceiver provides constant visibility into active line statistics. It gives technicians instant access to vital readouts like real-time temperature, internal voltage, and laser power levels. Having this data on hand makes troubleshooting simple and prevents unexpected network downtime.
