The Tripp Lite N784 Series Media Converter is a standalone physical layer device designed to bridge 10/100BaseT(X) Ethernet segments with 100BaseFX fiber optic segments within the same network. This converter facilitates seamless communication between twisted pair (TP) and fiber optic cabling, making it suitable for extending network reach or integrating different network media types.

Function Description:

The primary function of the N784 Series is to convert electrical signals from a 10/100BaseT(X) Ethernet port to optical signals for a 100BaseFX fiber port, and vice versa. It supports both 10 Mbps and 100 Mbps Ethernet speeds, and can operate in full-duplex or half-duplex modes on both the TP and FX sides. The device is equipped with auto MDI/MDI-X functionality on its Ethernet port, simplifying connection to either a NIC-type (MDI) or HUB/Switch-type (MDI-X) port without requiring a specific cable type (straight-through or cross-over).

A key feature of this media converter is its support for Link Fault Pass-through (LFP). LFP is a diagnostic function that allows the converter to propagate link status from one port to the other, notifying remote nodes of network link failures. If the TP port loses its link (e.g., cable unplugged), the converter stops transmitting over the fiber port, causing the remote fiber link to fail. Similarly, if the fiber link fails, the converter restarts auto-negotiation on the TP port but remains in a link failure state, causing the remote TP node link to fail. This feature enhances network maintainability by making it easier to trace and identify the source of link failures. It's important to note that LFP functionality works only when two LFP-capable converters from the same manufacturer are used as a pair. Using an odd number of converters or models that do not support LFP will prevent this function from working.

Important Technical Specifications:

Models: N784-001-SC (SC type fiber connection) and N784-001-ST (ST type fiber connection). Both models are multi-mode.
Standards: IEEE 802.3u (10/100Base-TX, 100Base-FX) and IEEE 802.3x-compliant for full-duplex back pressure flow control for half-duplex.
Fiber Cable: Compatible with 50/125, 62.5/125, or 100/140 µm multi-mode fiber.
Wavelength: 1310 nm.
TP Cable Limitations: Cat. 5 and up, up to 100 meters.
Converter Fiber Cable Limitations: Multi-mode, up to 2 km.
Power Requirement: 1A@+5VDC from AC-DC Adapter or 0.5A@+5VDC from USB port.
Ambient Temperature: 32°F to 122°F (0°C to 50°C).
Humidity: 5% to 90%.
Dimensions (HxWxD): 1.03 x 2.76 x 3.70 in. (26.2 x 70.3 x 94 mm).

Usage Features:

The N784 Series offers flexible power input options:

AC-DC Power Adapter: The converter can be powered via an external AC-DC power adapter (100-240V included). DIP switch settings must be configured to enable this power source.
Power Over USB: Alternatively, the device can draw power from a USB port on a hosting device (e.g., a PC). This requires setting the DIP switch to the USB side and connecting a USB B-to-Type A cable. It's crucial that the PC's power is turned on for the converter to receive power in this mode.

DIP Switch Settings:

A set of DIP switches on the side panel allows for configuration of various operational parameters:

Power Input: Selects between AC-DC adapter or USB power.
FX Duplex Mode: Configures the fiber port for full-duplex (default) or half-duplex operation.
Link Fault Pass-Through (LFP): Enables (default) or disables LFP functionality.
TP Duplex Mode: Configures the twisted pair port for full-duplex (default) or half-duplex operation.
TP Speed: Sets the twisted pair port speed to 100 Mbps (default) or 10 Mbps.
TP Auto-negotiation/Force Mode: Allows for auto-negotiation (default) or forces the TP port to 10M or half-duplex.
- Note: When forcing TP settings (10 Mbps and half-duplex), DIP Switch 1 must be set to "FORCE".
- Important: After adjusting DIP switches, the converter must be rebooted for the new settings to take effect.

LED Indicators:

The front panel features several LEDs to provide real-time status information:

FX LNK/ACT (Green): Lit when the FX port is linked; blinks when the FX port is transmitting data.
FX FDX/COL (Amber): Lit when full-duplex mode is active; off when half-duplex is active; blinks when a collision occurs.
TP LNK/ACT (Green): Lit when the TP port is linked; blinks when the FX port is transmitting data.
TP 100 (Green): Lit when the TP port is transmitting data at 100 Mbps; off when the TP port is transmitting data at 10 Mbps.
PWR (Green): Lit when +5V power is supplied.

Maintenance Features:

While the manual does not detail specific user-level maintenance procedures beyond proper connection and DIP switch configuration, the robust design and diagnostic features contribute to ease of maintenance:

Link Fault Pass-through (LFP): This feature is a significant aid in network troubleshooting. By propagating link failures, it helps administrators quickly pinpoint where a network link has broken, reducing downtime and diagnostic effort.
LED Indicators: The comprehensive set of LED indicators provides immediate visual feedback on link status, speed, duplex mode, and power, allowing for quick assessment of the device's operational state and potential issues.
Durable Construction: Tripp Lite products are generally known for their manufacturing excellence and reliability, implying a design intended for long-term, stable operation.

The N784 Series Media Converter is a reliable and versatile solution for integrating different network media, offering essential features for network extension and fault diagnosis in various environments.
