The IFC-100PD is Power over Ethernet 10/100Base-TX to 100Base-FX non-managed PD(Power Device) Fiber converter, whichgive you the options to choose from the most popular fiber cabling connectors, ST, SC, FC. Both multi-mode and single modeconverter models are available as well as BiDi which allows bi-directional transmissions using only a single fiber cable. WithPower over Ethernet (PoE) feature, IFC-100PD takes power supply over Ethernet cable from PoE Ethernet Switch and may workwithout external power adapter. When auto-negotiation is selected, these units will automatically tailor themselves to convertboth half-duplex and full-duplex signals, according to IEEE802.3u standards. LED indicators signal the power status of theconverter, UTP port speed, Link, and duplex status, FX port Link and duplex status. The stand-alone converter may also beconcentrated into either the FMC-CH08 or FMC-CH17 non-managed chassis.
