LNK-1100WSFP is an Ethernet media converter that converts media transmission between UTP Copper cabling and fiber SFP (Small Form-Factor Plug gable) Transceivers. It complies with IEEE802.3, IEEE802.3u and IEEE802.3x standards. Presently it supports two types of media network connections: 10Base-T/100Base-TX, and 1000Base-FX, inter-converting electrical signals of 10Base-T/100Base-TX twisted pairs with optical signals of 100Base-FX. It extends the transmission distance of network from 100m via copper cable to 120 km via fiber optical cables.
