Overview
The Tripp Lite N784-001-ST is a 10/100 multimode fiber-to-Ethernet media converter that converts copper Ethernet connections to 100BaseFX fiber. It provides an RJ45 copper port and an ST duplex fiber port, allowing compatible network nodes to be connected over multimode fiber beyond the typical 100-meter copper Ethernet limit.
Network Conversion
The N784-001-ST supports 10BaseT and 100BaseT UTP Ethernet on the copper side and 100BaseFX on the fiber side. The RJ45 port automatically senses the network speed, while Auto MDI/MDI-X simplifies connection to compatible Ethernet devices without requiring a specific straight-through or crossover cable arrangement.
Fiber Connectivity
The fiber interface uses an ST duplex connector and supports multimode 50/125 fiber for distances up to 2km. With 62.5/125 multimode fiber, the specified maximum transmission distance is 550 meters. The optical wavelength is 1310nm.
Duplex and Link Fault Features
A selectable operating mode allows half- or full-duplex operation on the fiber port. Link Fault Pass-through (LFP) assists with tracing network link failures by passing link-status information between the copper and fiber sides.
Power and Status Monitoring
The converter supports two power options: the supplied external AC-to-DC adapter or a USB connection selected through the unit's power arrangement. Five LED indicators provide status information for power, fiber link/activity, fiber duplex/collision status, copper link/activity, and 10/100Mbps speed.
Key Features
- Converts 10/100BaseT UTP Ethernet to 100BaseFX multimode fiber
- ST duplex fiber interface with 1310nm wavelength
- Supports up to 2km over 50/125 multimode fiber
- Auto MDI/MDI-X and automatic 10/100Mbps copper speed sensing
- Selectable half/full-duplex fiber operation with Link Fault Pass-through
Applications
- Extending Ethernet connections beyond standard copper cable distances

- Campus and building network links
- Industrial or commercial network infrastructure requiring fiber conversion
- Network installations using existing ST-terminated multimode fiber
DC Supplies Product Note
Connector and fiber type should be confirmed before deployment. The N784-001-ST specifically uses an ST duplex fiber interface and multimode fiber; it is not a singlemode or SC-interface converter.
