Introduce
The Fast Fiber Converter Module (Auto MDI/MDIX) is a cost-effective
solution for the converting between 10/100Base-TX and 100Base-FX
cabling, It allows you to extend the cabling distance of your 100Base-FX
network up to 2 kilometers for multi-mode fiber or 30 kilometers for
single-mode fiber. The Fast Fiber Converter module gives you the option
to choose from the most popular fiber cabling connectors:
SC/ST/MT-RJ/VF-45 multi- mode fiber connector and SC single-mode
fiber connector. The Fast Fiber Converters module provides you with one
Fiber connector for your fiber optic cable and one Ethernet RJ-45 port
(Auto MDI/MDIX) for your 100BaseTX copper cable connection. There are
4 DIP- switches to set the operation mode for UTP, Fiber ports and link
loss forwarding function.
The Fast Fiber Converter Module also supported WDM technology that
offers a cost efficient solution and allows a grouping of different services
on existing optical fibers inside. WDM Converter module converts signals
between 10/100Base-TX and 100Base-FX cabling, and incorporates
WDM technology. The WDM technology makes transmit (TX) and receive
(RX) lines onto a single fiber, which reduces half cabling cost. A pair of
WDM converters (wavelength 1310 and 1550 nm) should be installed at
both ends of the single fiber cable. The fiber cabling can extend the
connectivity distance up to 20 kilometers. The UTP port (RJ-45 connector)
of this converter supports Auto MDI/MDIX function. Besides, there are 4
DIP- switches on the front panel of the converter to set the operation
mode and Link Loss Forwarding Function.
The Fast Fiber Converter Module can be slotted in Multi-Converter
Chassis up to 10 optional modular converter units, which allows your
network connectivity to be more flexible. It also can be use stand-alone
without slot in Multi-Converter Chassis.

Ports
RJ-45 Port (Auto MDI/MDIX): the Ethernet RJ-45 will auto-sense for
10Base-T or 100Base-TX connections. Auto MDI/MDIX means that
you can connect to another Switch or workstation without changing
non-crossover or crossover cabling.
Fiber Port: This port is for 100 Base-FX connection. We provide five
different style of fiber connectors (SC / SC single-mode / ST / MT-RJ /
VF-45) to meet your needs.
LEDIndicators
There are 6 diagnostic LEDs located on the Front panel of WDM
Converter. They provide real-time information of system and optional

DIP-switch
The DIP-switch is used to configure operation mode for LLF (Link Lost
Forwarding) and operation mode for UTP/Fiber port. The default value of
DIPswitch is OFF.
S/W No Status Description
ON UTP 100Mbps Full Duplex mode
1 OFF UTP Auto-Nego
ON Fiber in Half Duplex
2 OFF Fiber in Full Duplex
ON LLF Enable
3 OFF LLF Disable
ON Pure converter mode
4 OFF Switch Converter mode
Link Lost Forwarding (DIP-Switch 3): When LLF is enable, it allows
UTP link failures to be reported to the fiber side and also allows Fiber link
failure to be reported to the UTP side. Therefore, a link loss forward
feature is provided in both UTP and Fiber side.
Pure Converter mode (DIP-Switch 4): When pure converter mode is
enabling (on), it operates with the minimum latency. The transmission flow
does not wait until entire frame is ready, but instead it forwards the
received data immediately after the data being received. And TP port
should be forced at 100M in this application. When DIP-Switch is in Switch
Converter mode (off), the converter function is same as Switch Hub.
[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. Besides, if
you change the DIP-switch setting, please power off the converter and
power on again to make the setting effective.

Installing Converters module
This installation is only for mounted in converter chassis converter module.
You can follow the steps below to install converter module.
A、Remove the blank bracket by rotating thumbscrew counterclockwise.
Put the blank bracket aside, but don’t discard blanket bracket.
B、Open the rack mount ear kit. The kit contains two-rack mount ear
(with thumbscrew) and four screws.
C、Attach rack mount ear on both sides of the converter module by using
a screwdriver to secure the rack mount ears.
D. Install the converter module by inserting it into the guides and sliding it
in until it stops. Press it firmly until the power plug in the chassis plugs into
the converter module receptacle. Slide the converter module in smoothly.
E. Gently push the thumbscrews in and turn clockwise to tighten. Do not
over tighten the thumbscrews.

Cabling
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 single-mode connector type must use 9/125 μm
single-mode fiber cable. You can connect two devices in the distance
of 30 Kilometers in full duplex operation. For half-duplex operation,
the recommended maximum distance is 412 meters (1,352 ft.)
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.

11
Troubles shooting
Check the configuration DIP-switch. It must be setting in the same
operation mode with the link partner.
Select the proper UTP/Fiber cable to construct your network. The
single-mode converter must use single-mode fiber cable. Please
check that you are using the right cable.
