Mobile TV Group and Colorado Studios have designed and built a wide variety of HD outside broadcast mobile production trucks, which cover live games for a number of NBA, NHL, and Major League Basell teams. Many of the games are broadcast on Fox Sports, Root Sports, Altitude and Comcast Sports Networks.
According to MTVG, the LYNX Technik was the only manufacturer they could find that provided the full 18 wavelengths of CWDM coverage. The yellobriks support all wavelengths from 1270nm through 1610nm, which allows MTVG to maximize the number of HD-SDI feeds they can carry per strand of fiber. In addition, yellobriks offer passive optical multiplexing, which lessens the possibility of signal transmission failure.
MTVG carries 56 signal paths on the yellobrik systems: 38 signals from the main mobile unit (MU) to the companion unit (VMU), and 18 from the VMU to the MU. The companion unit is fully network to the main unit with extensive fiber connectivity. Yellobrik carries SDI links over fiber back and forth between the dual trucks to aid in the visual display monitoring of signals, deliver and receive embedded audio, and interface with a number of other systems in the main truck. The yellobrik’s are interfacing with a large variety of equipment including cameras, switchers, routers, servers, multiviewers and graphics engines.
MTVG is utilizing yellobrik CWDM SDI to fiber converters, fiber to SDI receivers, as well as CWDM multiplexers to meet this challenge. The OCM 1891 yellobrik mux/demux are compact CWDM passive 9 channel optical multiplexer / demultiplexer designed to send or receive up to 9 individual signals over a single fiber link. MTVG is using this modules upgrade port to connect to the OCM 1892, which expands the capability of the modules to 18 CWDM channels. These devices are capable of multiplexing multiple signals over a single fiber and then splitting them back into individual signals when received.
The OTT 1842 CWDM SDI to fiber converters and ORR 1802 fiber to SDI receivers provide a very cost-effective CWDM fiber transmission system for up to 18 signals in a single fiber link. All yellobrik fiber solutions are designed to combat the restrictions involved with the distribution of uncompressed broadcast quality video signals over long distances.
