The Thor F-GET-TR-SFP Ethernet Transceiver with SFP is used for transporting a Gigabit Ethernet port over a fiber from one location to another. The units work in pairs with a transceiver on each end of the link. Any network cable connected to the RJ-45 port one one unit is transported to the corresponding RJ-45 port on the second unit. Our units work transparently, meaning they are non-IP addressable and any network traffic traveling through the the fiber link remains unmodified. Any two devices that are connected over the fiber link appear to be directly connected by a standard network cable. This is useful for connecting switches or other network devices in different buildings or for extending an IP network to a far away location. We also offer custom equipment to incorporate more signals onto a single fiber. In addition to Ethernet you can also carry video and audio channels, telephone lines, E1 or T1 links, or even satellite signals all over a single fiber. Our units have a maximum transmission distance of 120 km when used with singlemode fiber. We feature easy to read diagnostic LED's for continuous monitoring of link status and network speed.
