GoodTop 4-Port Gigabit PoE Extender, 1000M, IEEE 802.3af/at, 100m Extension

The GoodTop 4-port Gigabit PoE extender sits in the middle of a long run and passes both power and data on to the next device. One port takes the incoming PoE feed and three ports send it on. Each port supports IEEE 802.3af/at, and the unit adapts to 10/100/1000 Mbps on its own.

It extends the power and network data of PoE devices by a further 100m. Output ports 1 to 3 support VLAN isolation, which helps network performance and security, and the extender can be cascaded to three levels, so one cable can reach a far outbuilding or a camera at the end of a long garden.

The power limits are worth knowing. Maximum input is 30W. Each output port can give up to 15.4W, and the total output is 25W across the three ports. That suits a few IP cameras or an access point, but not a set of power-hungry devices.

The extender has no power supply of its own. It is made to extend PoE and data for PoE devices only, so it works when it is connected to a PoE source such as a PoE switch or an NVR with PoE ports. Use at least Cat5e cable; Cat6 is recommended for steady data and power.

Setup is plug and play with no configuration. For the cable between units see wire and cable.
