Product Specification

Allen Bradley 1783-SFP100LX Fiber Transceiver

Key Features

Technical Specifications

Applications

The 1783‑SFP100LX is designed for use with Rockwell Automation products that support SFP modules, including:

• Stratix Switches – Provides fiber uplink connectivity for Stratix industrial Ethernet switches 

• FLEX 5000 Adapters – Supports EtherNet/IP network transceiver modules in SFP format 

• Stratix 5400/5700 Switches – Offers fiber‑optic uplink interfaces for send (TX) and receive (RX) 

• Industrial Network Backbones – Enables long‑distance connections between facilities or remote equipment

• Government and Infrastructure Projects – TAA compliance qualifies it for use in federally funded applications 

Compatibility Notes

• Certified Modules: Use only Rockwell Automation SFP modules (1783‑SFP100FX, 1783‑SFP100LX, 1783‑SFP1GSX, or 1783‑SFP1GLX) to ensure proper initialization by device firmware .

• Cable Matching: Both ends of a fiber link must use identical fiber types and modules .

• Auto‑Negotiation: Fiber SFP modules do not support auto‑negotiation; the network settings must be configured accordingly .

• Third‑Party Compatibility: Compatible transceivers are available from third‑party suppliers, but Rockwell Automation strongly recommends official modules to avoid initialization failures .

Key Benefits

Important Notes

• Installation Precautions: Do not insert or remove the SFP module with fiber‑optic cables attached, as this can damage cables or connectors .

• Hot‑Swapping: The module supports live insertion and removal, but it is recommended to avoid excessive handling to prolong its useful life .

• Physical Interference: If the SFP module cannot be fully inserted, rotate it 180° and try again; do not force insertion .

• Eye Safety Warning: Looking into optical SFP transceivers can pose an eye hazard under certain conditions .
