Key Features of Arista Networks SFP-100FX-31 Compatible LINK-PP 155M SFP
Arista Networks SFP-100FX-31 Compatible LINK-PP stands as a reliable multi-mode SFP transceiver tailored for everyday enterprise networking. It packages 155 Mbps speeds, a 1310nm optical core, and a 2km reach into a standard hot-swappable design equipped with dual-fiber LC ports and built-in telemetry. This compact hardware delivers a balanced mix of steady signal delivery and smart link management for local infrastructure.
Built on universal engineering rules, this module strictly follows the SFP MSA and SFF-8472 guidelines. Its dual-fiber layout pairs perfectly with standard patch cables to ensure hassle-free plug-and-play installation. These strict design standards guarantee broad compatibility across various hardware brands without requiring complex configuration.
SFP-100FX-31: 155 Mbps Connectivity for Campus Access Layers
This hardware operates at a steady 155Mbps line rate, ideal for maintaining Fast Ethernet connections at the edge of your network. It efficiently hooks up desktop lines, entry-level switches, and local workgroups to your main building distribution frame. It provides a practical bandwidth choice that keeps older, vital systems running smoothly.
SFP-100FX-31 Module with 1310nm Wavelength
The transceiver relies on an FP laser and PIN photo detector matched to the 1310nm window. This specific optical setup offers low distortion and predictable signaling across multi-mode fiber runs. By utilizing this clean frequency, the module maintains a highly stable light path that resists basic signal noise.
SFP-100FX-31 Module Supporting 2km Transmission
With a maximum physical range of 2km, this unit is built to link separate wings of a facility or cross small outdoor yards. It covers standard intra-campus gaps easily without requiring expensive single-mode fiber installations. It offers a cost-conscious way to handle multi-floor or building-to-building links.
SFP-100FX-31 Module with Duplex LC Interface
The optical face features a tight-fitting duplex LC connector that prevents accidental cable disconnects. Its compact twin-port shape allows network admins to pack more fiber links into tight patch panels and high-density line cards. This small footprint helps save valuable rack space in crowded IT closets.
SFP-100FX-31 Module with DOM for Real-Time Monitoring
Onboard Digital Optical Monitoring (DOM) gives technicians a direct window into the module's daily health. The system tracks internal operating temperatures, voltage levels, and laser power settings on the fly. This active data stream alerts teams to line degradation before an actual network outage occurs.

Modules perform exactly up to the 2km MMF SFP module specifications on our multi-mode network. However, the plastic dust caps on the Duplex LC ports were a bit loose in the bag and one had fallen off. Cleaned the optical face just in case and it works flawlessly. Good cheap alternative to expensive OEM optics.

I handle the network infrastructure for a large hospital campus where we still have legacy medical imaging systems hooked up via 155Mbps multi-mode fiber lines. When our OEM transceivers started failing, the original vendor quoted an absurd lead time and price. We decided to test these Fast Ethernet 155M SFP modules as an alternative. Not only did they link up instantly with our legacy edge switches, but the DDM diagnostic data is actually cleaner than the original OEM optics. They have handled heavy DICOM image transfers for over 3 weeks straight without a single interface error. Exceptional product!

Our telecom firm specializes in retrofitting older multi-tenant building complexes where pulling new single-mode fiber is cost-prohibitive, so we have to maximize the existing legacy multi-mode fiber infrastructure. These 2km MMF SFP modules allow us to deliver stable 155Mbps dedicated circuits for legacy building control systems and fire alarms. The Duplex LC connectors have solid mechanical latching, preventing loose connections in vibrating telecom risers. We've purchased over 100 units so far, and the failure rate is exactly 0%. Will continue to source our multimode optics transceivers from here.

We deployed these 2km MMF SFP modules in an enterprise office environment for old print-server VLAN lines. They support the standard STM-1/OC-3 protocols flawlessly. DDM telemetry shows very stable TX/RX power levels.
