General
The industrial 10/100BASE-TX to 100BASE-FX media converter series provides industrial strength Ethernet copper-tofiber media conversion, allowing for 10Base-T-100Base-FX
or 100Base-TX-100Base-FX over multimode or optional
single-mode fiber optical media.
Features
• Conversion for 10Base-T-100Base-FX or 100Base-TX-
100Base-FX over multimode or single-mode fiber
• Comprehensive configuration settings to increase the flex-
ibility for more application needs
• Smart-Forward operating mode, which uses store-and-for-
ward mechanism for packet forwarding normally when
both media ends operate at different speed, but switch to
direct conversion automatically to achieve the least latency
when both media ends operate at the same speed.
• Link Fault Pass Through function which allows link fault
status passes through from one end to another end transparently.
Enhanced Features for Industrial Environment
• Wide operating Temperature: -20
o
C to +70oC
• Wide operating power voltage: +7 ~ 30VDC
• Power interfaces: Terminal block and DC jack
• DIN rail mounting and panel mounting support for
industrial enclosure
• Enhanced Emission and Immunity performance
Functions
• Convert speed and media type
• Support full wire speed conversion
• Support 10Mbps and 100Mbps speed on TP port
• Auto MDI/MDI-X detection function on the TP port
• Auto-negotiation function on the TP port
• Link fault pass through function
• Transparent to 802.1Q VLAN tagged packets
• Far End Fault function on FX (fiber) port
• Support full duplex 802.3x flow control and half duplex
back pressure flow control for store-and-forward mode
• Support wide range of fiber options on the FX port
• Low power consumption

Operating Temperature model dependent
Storage Temperature -40 ~ 85oC
Relative Humidity 5% ~ 90%
LFPT - Link Fault Pass Through function allows a link
fault detected on one port will force a link down on another
port at the same time.
Smart Forward Mode - the converter can change to direct
conversion automatically when it detects same speed on both
TP port and FX port. Direct conversion method converts the
signal between TP port and FX port without storing the received packet on one port then forwarding to another port.
The media converter operates with the mini mum latency.
