Direct from the manufacturer - The Enable-IT 828 Gigabit Ethernet and PoE+ Extension Unit is the worlds First copper Gigabit solution in the industry today. It can be used with your existing PoE Midspan switch, or PoE Injector. The 828 can drive your Gigabit Ethernet and your PoE up to 240m or 800ft or daisychained with another standalone 828 Units up to 480m / 1,600ft. This 828 unit can also be used with an (1) Enable-IT 828P and (2) 828 units to reach 660m or 2,000ft. This cost effective unit blows away any previous solution including fiber for very quick plug and go installation of PoE IP cameras, PoE Access Points and remote LAN segments. The Enable-IT 828 drives industry standard 1000baseT Ethernet signals to over two times the restricted IEEE standard Ethernet distance when combined in a series of multiple 828 units and uses PoE+ Power. This cost-effective solution eliminates many of the limitations and high costs for extending LAN cabling today. The 828 Series Solution is a standalone PoE+ powered Gigabit Ethernet Repeater that extends the range of your Gigabit Ethernet to an unpowered remote location. This is ideal for installing high powered PoE+ cameras remotely using only a CAT5e or CAT6 rated 100m cabling. Selectable DIP switch for disabling PoE output to enable standard non PoE LAN devices. Made in the USA with Quality and Pride. * Enable-IT 828 - Pricing is for an unpowered unit.
