48-port 10G Managed Ring PoE Switch
Managed PoE Switch Overview
The LNK-A208GP-SFP is a high-performance 48-port Power over Ethernet switch
featuring 48x 10/100/1000M RJ45 ports (802.3af/at Power over Ethernet+)
and 4x 10G SFP+ uplinks. This delivers enterprise-grade switching with L2+ features
(Virtual Local Area Network, Quality of Service, Access Control Lists)
and advanced security (Spanning Tree Protocol/Routing Switch Protocol, port isolation).
This product is ideal for large-scale deployments, offering web/CLI/SNMP management,
9.6K jumbo frames and per-port PoE control. It is perfect for IP surveillance, WiFi 6
and industrial networks.
