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.
INDUSTRIAL ENHANCEMENT
For industrial environment, the converters are designed with the following enhanced features exceeding that of
commercial media converters:
zHigh and wide operating Temperature
zWide operating voltage range for DC power input
zPower input interfaces: Terminal block for industrial power supply and DC jack for typical power adapter
