The Allen Bradley 1783-MX08F is a fiber expansion module for the Stratix 8000 managed Ethernet switch family. It adds eight 100BASE-FX fiber-optic Ethernet ports to a compatible Stratix 8000 or Stratix 8300 switch, making it suitable for industrial networks that need fiber connections between distributed equipment.
The module is useful when network segments extend beyond the practical range of copper Ethernet or when fiber is preferred for communication between control cabinets, production areas, and other network locations. Its eight-port configuration allows multiple fiber links to be incorporated into the same switching architecture.
The 1783-MX08F uses LC fiber-optic connectors and operates at 100 Mbps in full-duplex mode. It supports graded-index multimode fiber with a maximum specified cable length of 2000 m, making it particularly suitable for distributed Fast Ethernet networks.

The 1783-MX08F operates as an expansion module attached to a compatible Stratix 8000 or Stratix 8300 managed Ethernet switch. Its eight 100BASE-FX ports provide additional fiber-based Ethernet interfaces within the switching architecture.
Each fiber port uses an LC connector and communicates at 100 Mbps in full-duplex mode. A compatible multimode fiber connection carries Ethernet data between the expansion module and another network device, such as a remote industrial switch.
For a factory network, the module can be installed in one control cabinet while a fiber link runs to another cabinet or production area. This arrangement allows network communication to extend across the facility without relying on a copper Ethernet connection between the two locations.

The 1783-MX08F provides eight 100BASE-FX fiber-optic Ethernet ports with IEC 61754-20 LC connectors. It is intended for graded-index multimode fiber connections.
The specified maximum optical cable length is 2000 m when using graded-index multimode fiber. The actual usable distance also depends on the fiber characteristics and optical link budget.
The 1783-MX08F has eight integrated 100BASE-FX fiber-optic ports, while the 1783-MX08S provides eight SFP slots. The 1783-MX08F therefore uses a fixed 100BASE-FX fiber interface, whereas the SFP-based model allows the interface to be determined by the installed compatible SFP modules.
The 1783-MX08F has been discontinued by Allen Bradley/Rockwell Automation. It is therefore primarily relevant to existing Stratix 8000 installations, replacement requirements, and maintenance of legacy industrial Ethernet systems.
