Modern video installations depend on high-quality, high-speed data communications almost as much as they depend on video circuits. With the MD-003 E-TXRX and E-RXTX card set installed in an MD-003 chassis, many different types of Ethernet and IP traffic can easily be supported.
Four completely independent, bi-directional Ethernet channels on each card ensure that data flows on the individual ports will be kept separate, allowing each flow to operate at full wire-speed rates and with total isolation. This permits data from different user networks to be transported with complete security and no possibility of data traffic collisions over a common fiber backbone. In addition, two analog audio channels are provided for intercom or low speed data connections.
Through the use of Wavelength Division Multiplexing (WDM), an MD-003 system can support multiple channels of video on a single fiber, in addition to one or more groups of Ethernet links. Because the E-TXRX and E-RXTX are both bi-directional modules, each module occupies two slots in both the origin and
destination chassis.
Two different frames have been designed for MD-003 series transport modules to offer tremendous scalability:
The 3RU-shelf provides 16 module slots in a variety of WDM configurations, including 16:1, dual 8:1, quad 4:1 and 16 individual fibers.
The 1RU shelf provides two optical module slots, along with two slots that can be used for the wide range of MD2000 video processing and compression modules, including the HD270Coax, HD-GigE, up and down converters, A/D and D/A converters, audio embedders, frame synchronizers, and a constantly evolving list of new functions.
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.
