ADD-FMCP-FX-SC is a 10/100Base-TX to 100Base-FX media converter, which converts 100Base Copper to 100Base-FX via a 1310nm multi-mode fiber (MMF) SC Connector, allowing a distance reach up to 2km. Complied with IEEE802.3af standard, the AC/DC powered PoE media converter is a Power Sourcing Equipment (PSE) which combines data transferred over a fiber optic link with 48V (or other voltage) power supply, providing power to IEEE802.3af powered device (PD) over CAT5 UTP cable (cable length up to 100meters / 330feets). The converter includes a single port PSE controller, which offers PD signature sensing and power monitoring features. Other features include over-current protection, LFP function. The LFP (Link Fault Pass-through) allows the media converter to monitor both the fiber and copper RX port for loss of signal. In case of a loss of RX signal on one media port, the converter will automatically disable the TX signal to the other media port, thus passing through the link fault. AddOn - Network Upgrade Media Converters and Network Interface Cards are 100% compliant for all of our networking needs. ADD-FMCP-FX-SC provides a cost effective conversion from 100Base Copper to 100Base-FX fiber, while extending your network reach beyond the 100m reach limitation of copper.
