FR388 series is a 5 port (1FX+4TP) 10/100/1000M PoE (PSE) Ethernet Switch. The optical fiber port can greatly extend the transmission distance limitation of normal CAT5e UTP cable. All the four 10/100/1000Mbps UTP RJ-45 ports supports full duplex 10/100/1000M connectivity (half duplex only supported in 10/100M mode). Complied with IEEE802.3at and IEEE802.3af standard, the PoE(PSE) Ethernet Switch is a Power Sourcing Equipment (PSE) which combines data transfered over cable with 48V (typical) power supply, providing power to IEEE802.3at /IEEE802.3af powered device (PD) over CAT5e UTP cable (cable length up to 100meters / 330feets). All the four UTP RJ-45 ports are organized to be PoE output port and each PoE port can output up to 60Watts (DC 48V/1.2A) power into CAT5e twisted-pair cable.
