The openGear platform has a new 3G fiber-optic transport option, with the IBC 2009 introduction by MultiDyne Video & Fiber Optic Systems of its new HD-4400 four-channel fiber optic transport system.
This high-density, multirate, 3G HD-SDI SMPTE system, with a 4x4 matrix on both the transmitter and receiver, is one of the first products MultiDyne has designed as part of its participation in the openGear terminal equipment platform group.
Founded by Ross Video, the openGear platform is based on an open architecture, 2 RU 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 will give customers another option for fiber optic transport without the need to invest in multiple frame standards.
“The MultiDyne HD-4400 designed under the openGear standard will continue to give broadcasters the flexibility they desire when it comes to selecting only the most advanced technology compatible with their existing equipment,” said Jim Jachetta, senior vice president of engineering and product development. “The HD-4400 is perfect to meet the demands for today’s high definition, on-the-go sports or news production environments. Nowadays, 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.”
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 Mbps to 3 Gbps 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.
Several 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.
