HHD-120G-20

G-NET Gigabit Ethernet Fiber Media Converter HHD-120G-20 uses the switching technology to conduct media conversion,which meets the standards of IEEE802.3, IEEE802.3u, IEEE802.3z and IEEE802.3ab, IEEE 802.3x. It supports two types of media network connections:10Base-T/100Base-T . It can conduct mutual conversion between 10Base-T/100Base twisted pair electrical signal and 1000Base-SX/LX optical signals. It extends the transmission distance of a network from 100m over copper wires to 20Km. This fiber converter supports transmission in dual fiber single-mode fiber.
