The MD-003 GETR 4-Port Gigabit Ethernet Transceiver provides a cost effective, robust single card solution for converged broadcast network needs. This video-aware, layer 2 Ethernet switch manages bandwidth for multiple input ports, allowing a single high speed optical Gigabit Ethernet link to be intelligently managed. Video signals are given priority whenever they are active, while data can be transported on the remaining bandwidth. When the video signals are removed, data bandwidth is automatically increased.
The GETR provides non-blocking, wire speed port aggregation that combines 4 standard Gigabit Ethernet interfaces and one optional 10/100 RJ45 interface into a single optical interface. The bandwidth on each port can be controlled in 1 Mbps increments.
Two modes of operation can be configured; “VLAN mode” and “PORT mode.” In VLAN mode, priority can be assigned to video traffic and provide provisioned bandwidth for specific VLAN Groups with Guaranteed QoS while other traffic is best effort. In PORT mode, video traffic is assigned priority based on port order from 1-4. In each mode, non-video traffic speeds up to full bandwidth when video is not present at the input.
Industry standard SFP optics are used in the optical transceiver port to support common sparing with other fiber transport equipment. The optical port can also be rate-limited to ensure compatibility with carrier service level agreements.
In addition to the E-TXRX/E-RXTX modules, the MD-003 series includes and STM-1/OC3 transmitter and receiver along with a universal video interface card that supports HD-SDI, SD-SDI, SDTI and DVB/ASI video signals.
Media Links’ HD-GigE compression codecs can be used with the GETRin the MD-003 carrier-class 1RU shelf to provide a compact, cost effective multi-service IP transport solution.
The MD-003 GETR is ideal for HD, SD, DVB-ASI video transport over IPnetworks as well as shared use with file transfer, VOIP, Internet access and other IP applications. Combining multiple IP services onto a single fiber reduces the need for remote switches on the network and uses fewer ports on core IP routers.
Note: Each MD-003-GETR must be ordered with one Optical Plug-in (SFP) module from above list.
