Connect with fiber and provide power to remote PoE devices. A low-cost, economical solution for powering PoE devices over the same CATx link used for data communications. Powered device (PD) signature sending detects when a PoE device is connected. Protects against damage caused by overcurrent events and offers undercurrent detection. Link fault passthrough monitors both copper and fiber receive ports for loss of signal. Far-end fault detection prevents the loss of valuable data from it being sent over an invalid link. Supports 802.3x flow control on full-duplex ports and backpressure on 10BASE-T/100BASE-TX half-duplex ports. Jumbo frame support (2 KB, normal mode; 9 KB, cut-through mode). Copper port autonegotiates for network speed and features Auto MDI-X for easy cabling. LEDs indicate when it is feeding PoE power as well as when power is interrupted. RoHS compliant. Connect Gigabit-speed fiber optic to a 10-/100-/1000-Mbps copper UTP segment while also powering 802.3af devices at the end of the CAT5 run.
