Power over Ethernet (PoE ++) for existing and new FTTO infrastructures

Typical applications for PoE are wireless LAN access points, IP cameras and Voice over IP phones. For Building Internet of Things (BIoT) the number of possible applications grows continuously. Are performance classes in the range of 60 or 90W really needed today?

 

Typical applications for PoE are wireless LAN accesspoints, IP cameras and Voice over IP phones. For Building Internet of Things (BIoT) the number of possible applications grows continuously. Are per-formance classes in the range of 60 or 90W really needed today? This can be answered with a clear „yes".

Already today wireless LAN access points are inneed for more and more power to support the latest wireless LAN standard IEEE802.11ax (WiFi 6) and presuppose that supply of PoE++ to provide fullfunctionality.

In addition to wireless LAN access points, also PTZ IR IP cameras need very high power level (up to 71W) using PoE++.

How can the increasing PoE demand be met withthe current network infrastructure and the used network components? The current Nexans LANactiveGigaSwitch V5 supports 4x PoE+ via the user ports with up to 30W per port. Thanks to the modularity of the switch, the head is removable and can beexchanged with a head supporting PoE++.

This enables existing FTTO installations to upgradewith the new PoE++ standard and retrieve up to4x PoE++ with an entire power budget up to150W per switch.
