1. 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-sense connection speed, auto-negotiates half/full
duplex modes and auto-selects MDIX media type. The fiber
connectors come with multimode or singlemode, SC, ST or SFP
connector to provide necessary connection interface and distance
capabilities.
LevelOne have designed 19” racks to organize media converters the
smart way by providing a single power supply. With the
Plug-and-play technology, the converter is easy to set-up and run.
For simple, cost-effective network design, LevelOne converter
series is the perfect solution to bridge the complex network
infrastructure.

2.4. DIP-switch
The DIP-switch is used to configure operation mode for LLF (Link
Lost Forwarding) and Flow-Control function for UTP/Fiber port. The
default value of DIP switch is OFF.

Link Lost Forwarding:
When LLF is enable, 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 error.

3. Cabling
Fast Ethernet Module
§ Twisted-pair segment can be use 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 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 a 2-kilometer (6,562 ft.) distance.
§ Fiber segment using single-mode connector type must use
8/125 or 9/125 um single-mode fiber cable. You can connect two
devices in the 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.
§ Fiber segment using single-mode connector type must use
8/125 or 9/125 um single-mode fiber cable. You can connect two
devices in the distance of 80 Kilometers in full duplex operation.
For half-duplex operation, the recommended maximum distance
is 412 meters (1,352 ft.)
