Outdoor events can be tricky when transmissions come into play for television. Signals need to be received over long distances, and up until now this could be problematical. ETL Systems, a designer and manufacturer of RF distribution equipment for satellite communications has launched its Outdoor Unit Fiber Extender and Indoor Receive Unit, a new extension to the Stingray Fiber Series which will be on display at this year’s IBC.
ETL's new Stingray Fiber Series provides module to module isolation that excels outdoors at events such as football, golf and music concerts as it is suitable for installations where signals need to be sentup to 10km (6.21 miles) in distance. Additionally, outdoor camera and microphone broadcast applications that involve signals received over long distances do well with the new twin channel RF over Fiber links.
The new innovation works through an outdoor transmit fiber extender module, connected to an omnidirectional antenna that receives the wireless camera signals direct from the live events. The signal is then distributed to an indoor fiber receiver unit, which could be located in or nearby an SNG truck or master control room, which then re-broadcasts the signal.
Ian Hilditch, CEO of ETL Systems explained, “ETL’s new fiber extender is lightweight, has a waterproof housing, is affordable and is compact. It is a much more efficient and reliable means of communication for live broadcasts over potentially long distances, rather than using traditional coaxial cables. The twin channel operation enables users to diversify their antennas in different locations, which helps maintain good signal coverage for difficult environments or in large structures such as major sports stadia, like in this year’s Olympic Games in Rio.”
The transmitters and receivers can be provided in rugged waterproof housings or a rack mounted chassis and handle a broad frequency range of RF signals from 50 to 2450 MHz, making them compatible with a variety of camera/microphone products.
Additionally, alongside these new units, visitors to the ETL booth at IBC will also be able to see new CWDM modules that can transmit up to 8 RF signals on a single cable up to 55km distances—with low loss—for longer distance transmissions.
Ian Hilditch and other ETL representatives will be at the Amsterdam event.
Hilditch continued, “IBC will bring together major players in the broadcasting industry. It is a place where we can come together to discuss how we can develop on the delivery and management of entertainment and news content worldwide. Visitors to our stand will not only get the chance to see our products, but also get a greater understanding of how our fiber links work.”
