1. Introduction
The industrial 10/100BASE-TX to 100BASE-FX media converter series provides industrial strength Ethernet
copper-to-fiber media conversion, allowing for 10Base-T-100Base-FX or 100Base-TX-100Base-FX over
multi-mode or optional single-mode fiber optical media.
In addition to the basic media conversion functions, the converters also provide some special functions to
enhance the flexibility for wide application needs as follows:
AUTO-NEGO FUNCTION
The copper port is featured this function which performs a negotiation process for the speed and duplex
configuration with the connected device automatically when each time a link is being established.
AUTO-CROSS FUNCTION
The copper port is featured this function that allows to auto-detect the twisted-pair signals and adapts itself to
form a valid MDI to MDI-X connection with the remote connected device automatically.
FAR END FAULT FUNCTION
The fiber port is facilitated with this function, which conforms to IEEE 802.3u 100BASE-FX specifications.
When the port detects a link failure on its receiving circuitry, it will send out an FEFI (Far End Fault Indication)
signal to the remote connected device to indicate a remote fault is detected. It also is capable to receive FEFI
signal sent from the remote link partner. Upon receiving an FEFI signal, it indicates a link failure occurred on
the transmitting path. This function allows the converter to report a fiber link fault even when a link failure
occurred on transmitting fiber cable.
SMART-FORWARDING FUNCTION
-5-
The converter uses store-and-forward mechanism for packet forwarding normally when both media ends

-6-
operate at different speed, but switches to direct conversion automatically and with the least latency when both
media ends operate at the same speed.
LINK FAULT PASS THROUGH FUNCTION
The function allows the link fault status passes through from one media end to another media end transparently.

1.4 Special Functions
Auto MDI/MDI-X Function
This function allows the TP port to auto-detect the twisted-pair signals and adapts itself to form a valid MDI to
MDI-X connection with the remote connected device automatically.
Auto-negotiation Function
The copper port is featured with auto-negotiation function and full capability in speed and duplex. It performs a
negotiation process for the speed and duplex configuration with the connected device automatically when each
time a link is being established.
Far End Fault Function
The FX port is facilitated with this function that conforms to IEEE 802.3u 100BASE-FX specifications. When
the FX port detects a link failure on its receiving circuitry, it will send out an FEFI (Far End Fault Indication)
signal to the remote connected device to indicate a remote fault is detected. It also is capable to receive FEFI
signal sent from the remote link partner. Upon receiving an FEFI signal, it notes a link failure occurred on the
transmitting path. This function allows the converter to report a fiber link fault even when a link failure
occurred on transmitting fiber cable.
-11-

Link Fault Pass Through Function
When this function is enabled, a link fault detected on the TP copper port will force a link down on the FX
fiber port and vice versa. Similarly, a link fault detected on the FX fiber port will also force a link down on the
TP copper port.
The following figure illustrates a link fault on the fiber segment between the local and remote media converter
devices is detected and both devices will force a link down on both copper segments.
The following figure illustrates another example. A link fault happened on the copper cable is detected by the
remote end. The fault is forwarded to the fiber segment and also forwarded to the copper cable at the local end
by remote device and local device respectively.
Smart-Forward Function
With this function, the media converter can change to direct conversion automatically when it detects same
speed on both copper port and fiber port. Direct conversion method converts the signal between the copper port
and the fiber port without storing the received packet on one port then forwarding to another port. The media
converter operates with the minimum latency and has no size limit to the forwarded packets. In the case of
100Mbps to 10Mbps conversion, the media converter adapts itself to store-and-forward method for such
unbalancing conversion automatically.
Note:
1. In direct conversion, be sure both devices connected to the TP port and FX port have same duplex mode for
proper transmission.
2. In direct conversion, 802.3x function is disabled and the media converter will not generate pause frame, but
just forwards the received pause frame directly from one port to another port.
