Product Usage Instructions
- Connect the RJ-45 Port on the front panel of the converter to the Ethernet device using an Ethernet cable.
- Connect the Fiber/SFP Connector on the front panel of the converter to the fiber optic network using a fiber optic cable.
- Ensure that the LED indicators on the front panel are displaying the correct status for the connection.
- If required, configure the DIP switch on the rear panel to enable Link Lost Forwarding (LLF) and Flow-Control function for the UTP/Fiber port.

Introduction
LevelOne media converters are Fast Ethernet 10/100Base-TX to 100Base-FX and
10/100/1000Base-T to 1000Base-SX/LX converters to provide the flexibility
required in network integration. The TX port auto-senses connection speed,
auto-negotiates half/full duplex modes and auto-selects MDIX media type. The
fiber connectors come with multimode or single mode, SC, ST, or SFP connectors
to provide the necessary connection interface and distance
capabilities. LevelOne has designed 19” racks to organize media converters the
smart way by providing a single power supply. With With plug-and-play
technology, the converter is easy to set up and run. For a simple, cost-
effective network design, the LevelOne converter series is the perfect
solution to bridge the complex network infrastructure.

DIP-switch
The DIP switch is used to configure the operation mode for LLF (Link Lost
Forwarding) and Flow-Control function for UTP/Fiber port. The default value of
the DIP switch is OFF.
Fast Ethernet Module/Gigabit Ethernet Module
| No | Status | Description |
|---|---|---|
| 1 | ON | LFP is Enable |
| OFF | LFP is Disable | |
| 2 | ON | Flow-Control function ENABLED |
| OFF | Flow-Control function DISABLED |
Link Lost Forwarding
When LLF is enabled, allow UTP link failures to be reported to the fiber side
and also allow Fiber link failure to be reported to the UTP side. Therefore, A
link loss forward feature is provided in both UTP and Fiber side.
Flow Control Function
Flow control stops and resumes the transmission of network traffic between two
connected peer nodes on a full-duplex Ethernet physical link. Controlling the
flow by pausing and restarting it prevents buffers on the nodes from
overflowing and dropping frames.
Note:
Please don’t change the DIP-switch setting when UTP or fiber port is
transmitting or receiving data. It may cause some data errors.
Cabling
Fast Ethernet Module
- The twisted-pair segments can be used as unshielded twisted pair (UTP) or shielded twisted pair (STP) cabling. The cable must comply with the IEEE 802.3u 100Base TX standard for Category 5. The cable between the converter and the link partner (switch, hub, workstation, etc.) must be less than 100 meters (328 ft.) long.
- Fiber segments using multi-mode connector type must use 50 or 62.5/125 um multi-mode fiber cable. You can connect two devices up to a 2-kilometer (6,562 ft.) distance.
- Fiber segments using single-mode connector type must use 8/125 or 9/125 um single-mode fiber cable. You can connect two devices at a distance of 40 Kilometers in full duplex operation.
- For half-duplex operation, the recommended maximum distance is 412 meters (1,352 ft.)
Gigabit Ethernet Module
- Using four twisted-pair, Category 5 cabling for RJ-45 port connection. The cable between the converter and the link partner (switch, hub, workstation, etc.) must be less than 100 meters (328 ft.) long.
- Fiber segment using multi-mode connector type must use 50 or 62.5/125 um multi-mode fiber cable. You can connect two devices up to 550m distances.
