New Companion Cards Further Extend openGear Family Capabilities
NEW YORK, OCTOBER, 2009 – MultiDyne Video & Fiber Optic Systems, a premier provider of fiber optic-based video and audio transport and routing solutions for broadcast and pro A/V applications, is featuring the openGear compatible HD-4400 four-channel fiber optic transport system at HD World 2009 (Booth 942). The high density, multirate, 3G HD-SDI SMPTE fiber optic transport system with a 4x4 matrix on both the transmitter and receiver was designed as one of MultiDyne’s first offerings as part of the openGear terminal equipment platform group. In addition, MultiDyne will also introduce several new openGear compatible cards in support of the HD-4400, giving users more options and combination choices.

Founded by Ross Video, the openGear platform is based on an open architecture, 2RU modular frame designed to accommodate up to 10 cards in the DFR-8310 frame and up to 20 cards in the DFR-8320 frame. The HD-4400 and its companion cards will give customers more options for fiber optic transport without the need to invest in multiple frame standards.
“MultiDyne’s new companion cards only further extend the capabilities of our HD-4400 solution designed under the openGear standard, giving broadcasters ultimate flexibility when it comes to selecting only the most advanced technology compatible with their existing equipment,” says Jim Jachetta, senior vice president of engineering and product development. “Mobile production is so complex that often two or three mobile production trucks are required. Several dozen 3G HD video feeds need to be shared between all these production vehicles, and with limited space in these trucks, the HD-4400 is the perfect high-density solution for video pool feed distribution. The new openGear companion cards in our product line-up will only make these situations easier, meeting the demands of today’s high definition, on-the-go sports and news production environments.”
Ideal for high-capacity fiber trunking of 3G HD-SDI signals in a broadcast facility, the HD-4400 transmitter card accepts four multi-rate HD-SDI electrical signals with speeds of 5 Mb to 3 Gb per second as inputs. These inputs are equalized, re-clocked and converted to four optical outputs. The receiver card accepts four fiber optic inputs and converts them to four fiber optic electrical outputs, which are re-clocked and line buffered. Both the transmitter and receiver cards include a 4x4 matrix switcher to cross connect any of the four input and output channels.
The HD-4400’s 4x4 switching and cross-connect feature provides 3G HD signal routing and automatic redundancy capability. The system can also transport four redundant 3G HD-SDI feeds with automatic protection switching, supporting SDI, HD-SDI, 3G HD-SDI, DVB, ASI and SMPTE standards 424M, 292M, 259M and 310M.
MultiDyne also expands its commitment to the openGear platform with the addition of several new companion cards to the HD-4400. These new companion cards will target a wide variety of applications, with features including fiber optic transport, signal distribution, conversion, embedding, de-embedding and synchronization. Solutions available immediately include the 4005 Triple 3G/HD/SD Re-clocking Distribution Amplifier, 4018 Quad Monitoring Converter – SDI to Analog Composite and the 4035 Input Processor for HD/SD Analog and HD/SD-SDI Input with audio embedding/de-embedding and frame Sync.
Additional model variations of the HD-4400 will also be available from MultiDyne, providing a variety of fiber transport and switching options for customers including the HD-4300, triple 3G HD-SDI option with a 3x3 switch for openGear, the HD-4200 dual 3G-HD-SDI with a 2x2 switch for openGear and a HD-4100 single 3G HD-SDI model with one 3G HD-SDI channel and no switch or protection switching.
