Planet VC-820M 8-Port VDSL2 + 2G TP/SFP Managed Switch

 

High Performance VDSL2 Data Rate over Existing Phone Lines

PLANET VC-820M is an 8-Port VDSL2 Managed CO (Central Office) Switch with 2 Gigabit TP/SFP combo interfaces. The VDSL2 CO Switch is perfectly designed for the networking applications of communities, network service providers, SIs, IP surveillance providers, etc. It is based on two core networking technologies, Ethernet and VDSL2 (Very-high-data-rate Digital Subscriber Line 2). Worked with PLANET VC-23x series of VDSL2 CPE (Customer Premises Equipment), the VC-820M offers the absolutely fastest data transmission speeds over the existing copper telephone lines providing an ideal solution to the last-mile connectivity.

 

Each VDSL2 interface of the VC-820M provides two copper phone ports, one for VDSL2 connection and the other one for POTS (Plain Old Telephone Service) connection. To share the existing phone line with POTS, the VC-820M has a built-in POTS splitter that helps the voice over telephone and network data to transmit over the same wire without being interrupted.
