GAOTek 1000M Dual Port Media Converter

This dual port media converter supports two types of media for network connection such as 10/100/1000 Base-T to 1000 Base SX/LX and connects these two types of segments to operate smoothly.



The GAOTek 1000M Dual Port Media Converter supports two types of media for network connections such as 10/100/1000 Base-T to 1000 Base SX/LX and connects these two types of segments to operate smoothly. This Media Converter can be used in a 16 slot chassis as a plug-in module and it transforms 1000Base-T (Copper Gigabit) media to 1000Base-SX/LX (Fiber Gigabit) media and vice versa. The 1000Base-T port supports full-duplex Gigabit connection at wire speed with RJ-45 connectors while the fiber Gigabit connection supports shortwave (SX) or long wave (LX) laser optics with multi-mode or single-mode SC type connectors. This converter will give your copper Gigabit connection the ability to interface with fiber connections over a distance up to 49.70 mi (80 km) whereas 10/100/1000 indicates that this media converter converts the electrical signal of a 10/100/1000 Ethernet signal from copper to fiber. Gigabit only switches can now be connected to 10/100 networks without the need to upgrade the 10/100 side, allowing network managers to add new equipment gradually.
