The Cudy POE40 is a 4-channel Gigabit PoE++ extender designed to extend your network infrastructure by transferring power and data from an existing PoE source to four different devices. With a metal casing for durability, it supports 802.3af/at/bt PoE standards to meet both legacy and next-generation power needs. The POE40 can receive high power input via the uplink port using the 802.3bt standard, requiring no external power adapter and offering easy installation. Key technical features include four-pair power transmission support on the uplink port and Mode A pin assignment on the downlink ports. When powered by a 60W or higher PoE switch, it can deliver up to 30W (802.3at) on two ports or up to 12.95W (802.3af) on all four ports. With a power consumption of only 2W, this extender provides transmission distances of up to 100 meters at Gigabit speeds using Cat.5e or higher cables. It is equipped with safety features such as polarity protection, overvoltage protection, and short-circuit protection. The Cudy POE40 is ideal for large areas with PoE-powered devices like IP cameras, wireless access points, and VoIP phones. It can be used to deliver both data and power to devices located far from a central PoE switch, such as in an office floor or warehouse. Its compact design supports desktop or wall-mount installation, making it easy to integrate into any environment. Additionally, you can daisy-chain up to three extenders to further expand your network.
