HiOSO FC610A is a 10/100Mbps adaptive fast Ethernet optical converter (also known as photoelectric media converter), which can convert 10Base-T and 100Base-TX twisted pair electrical signals to 100Base-FX optical signals. It extends the transmission distance of the network from the limit of 100m copper wire to 120Km(single-mode full-duplex mode). Support for two different network connection media types: 10/100Base-TX and 100Base-FX, through the use of switching technology and store-and-forward technology to achieve data transfer between the two network connection media. Supports dual-fiber multi-mode, dual-fiber single-mode and single-fiber single-mode fiber transmission.
