SFP Media Converter 10/100/1000BASE-T to 100/1000BASE-X

Product Description


Model: LNK-3012-SFP Series


LNK-3012-SFP is equipped with one 10/100/1000BASE-T RJ45 copper and one 100/1000BASE-X SFP fiber optic interface with built-in power supply. The media converter fulfills 100/1000M auto-sensation at fiber optic port, which increase the flexibility of the whole network. The SFP slot of the LNK-3012-SFP is compatible with 100BASE-FX and 1000BASE-SX / LX / WDM through SFP fiber-optic transceivers.

Customer can easily migrate from 100M fiber to Gigabit without changing customer premise equipment (CPE). Start using the LNK-3012-SFP in your current 100M infrastructure. When you are ready to move to Gigabit Ethernet, only change the central switch and all the LNK-3012-SFP will automatically adjust to Gigabit speed. This cuts the number of customer visits in half and reduce installation cost with 50%. No need for proprietary equipment, it is compatible with you existing Ethernet products and follows all the accepted standards.
