Acadia 1G 4-Port Ethernet Media Module

The 1 Gigabit Ethernet Module is intended to be used either as backbone connections between switches or, increasing, to connect directly to Client PCs. The module is available with both optical and electrical interfaces.

Highlights
• Inband, line-speed, routing.
• IEEE 802.3x full-duplex flow control. This allows the switch ports to send a pause command before input buffers overflow. Half-duplex ports support active backpressure (jamming).
• VLAN trunking or non-tagged access modes. This allows the switch ports to interoperate with popular tagged trunking schemes used by other vendors.
• Priority Queuing and Class of Service. These features allow you to prioritize traffic between particular stations or sets of stations to support jitter-sensitive applications.
