This product supports IEEE802.3 10 Base-T standard/IEEE 802.3u 100Base-TX/FX standard IEEE 802.3z 1000Base-TX/FX standard, IEEE 802.3x Flow control standard as well as full duplex and half duplex mode. The media converter transforms the transmission media of Ethernet signal from CAT5 100m to optical fiber 850/1310/1550nm. It can extend the transmission distance to several kilometers or hundred kilometers. All Media converters apply the new 0.25µm technology to improve the performance and to avoid the packet lost with long the transmission. It also reduce the delay time to less than 9.6 µs. Using media converter is an economical solution to achieve long distance transmission base on current status.
