Haishuo Ficom FC1000A 10/100/1000Mbps adaptive Gigabit Ethernet Fiber Converter uses the switching technology to conduct media conversion, which meets the standards of IEEE802.3, IEEE802.3u, IEEE802.3z and IEEE802.3ab. This kind of fiber converter supports two types of media network connections: 10base-T/100base-TX/1000base-T and 1000base-SX/LX. The fiber converter can conduct mutual conversion between 10base-T/100base-TX/1000base-T twisted pair electrical signal and 1000base-SX/LX optical signal. This kind of converter extends the transmission distance of a network from 100m over copper wires to 120Km. This fiber converter supports transmission in dual-fiber multi-mode dual-fiber single-mode and single-fiber single-mode fibers.
