Product Description Shipping & Payment Customer Reviews


10Gtek's A7S2-33-1GX1GT-SFP Media Converter is used to expanding existing Gigabit Ethernet networks. The easy implementation and expansion of 1000Base-TX/FX networks can be further assured with this converter.
The converter is completely transparent when connected so the network performs exactly the way it did before - only now, it allows the co-existence of both copper and fiber mediums. SFP connectors are available. Extra distances are possible with the single mode version delivering up to 20km connectivity per transmitted segment.
The A7S2-33-1GX1GT-SFP allows the installation of fiber cabling anywhere within a Gigabit Ethernet network topology by directly connecting to existing devices. Its compact modular design facilitates deployment in a narrow desktop location to save space.
