ComNet, a manufacturer of fiber optic transmission and networking equipment, introduced a four-port self-managed Ethernet switch, the CNGE2+2SMS. The switch has two copper TX ports and two Gigabit SFP Ethernet ports. These self-managed switches were designed to allow IP video to be introduced in multiple locations on a ring network topology without the cost and complexity a managed switch requires. The unit features Gigabit TX ports that take in IP video and two SFP optical ports that take in data from the previous network device and forward it optically to the next device in a ring topology. This very small-sized switch also has a PoE model. The switch allows the user to create a virtual VLAN that manages the Ethernet data being transported, thereby preventing network flooding. The CNGE2+2SMS is pre-programmed and meets the IEEE 802.1w rapid spanning tree protocol for a true self-healing network in the event of a path failure.
