Industrial Fiber Gigabit Media Converter
10/100/1000Base-T to 100/1000Base-FX With IEEE802.3bt/at/af PoE Injector

DF100GB is an industrial grade 100/1000Base-FX to 10/100/1000Base-T GbE media converter/Injector, which allows one Ethernet UTP RJ-45 port to be inter-changeably connected to one Fiber SFP port. In addition, the RJ-45 port is compliant with IEEE802.3bt/at/af standards to provide up to 90Watt Power over Ethernet (PoE). This PoE media converter combines the SFP fiber data with a 52~57VDC power input, and injects up to 90Watt to the IEEE802.3bt/at/af powered device (PD) over the existing CAT5 UTP cable.

The DF100GB converter includes a PD signature sensing and power monitoring features. The PoE features over-current protection (OCP), over-voltage protection (OVP), and over-temperature protection (OTP). With the Link Fault Pass-through (LFP) function, the DF100GB can monitor both the fiber and copper RX ports 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. It then sends out the far end fault (FEF) signal to stop sending link pulse to the link partner once a loss of the fiber RX signal is encountered. Then the link partner will synchronously stop sending data. FEF prevents loss of valuable data transmitted over invalid link. Combining the LFP and FEF troubleshooting features of DF100GB, both end devices can be notified of a loss of fiber link.
