Mobile TV Group Taps LYNX Technik for Critical CWDM Outside Broadcast Fiber Needs

Mobile TV Group through its Colorado Studios systems integration division has purchased two large LYNX Technik AG yellobrik CWDM fiber systems for its high definition outside broadcast production trucks. Mobile TV Group is using the yellobrik systems throughout the United States for live sports and entertainment production in its next generation 53-foot 36HDX and 37HDX mobile production trucks.

MTVG purchased two feature-packed yellobrik CWDM fiber systems to address a key challenge: they needed to link two production trucks to function as one fully integrated unit – a main equipment truck (MU) and a second companion truck (VMU) that serves as a user interface – all while using fiber instead of traditional coax. With this side-by-side dual mobile unit solution, MTVG is using yellobrik solutions to transmit and receive up to 56 HD-SDI signals flawlessly using only two fiber links. The main mobile truck houses the key equipment control room and electronics, and the second truck functions as an operator interface and monitoring vehicle connected to the main truck. This model provides an advanced technological solution for both home and visitor sports production teams.

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 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.

“We chose the LYNX Technik yellobrik equipment because it has the advanced capabilities that allow us to utilize an integrated fiber solution for our production truck workflow,” comments Philip Garvin, President and GM at Colorado Studios and Mobile TV Group. “We are extremely happy with the performance of the yellobrik solutions, and they have enabled us to move forward with a technologically advanced and compact solution at an affordable price – something we couldn’t accomplish before.”

In addition to their out-of-the-box, simple plug-and-play functionality, and multi-format support, yellobrik’s are the perfect choice where space is of concern. With easy configuration and setup, the MTVG team is able to focus on the key elements of event production with peace of mind about the yellobrik’s performance and fiber connectivity.

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.
