NAB, April 13 2011 – Portuguese UPSTAR Comunicacoes has selected Nevion, a leading transport solutions provider for broadcasters, service providers and government entities worldwide, to provide advanced multiplexing, conversion and management equipment for its long-haul optical fibre transport.
UPSTAR Comunicacoes, a joint venture between ZON Multimedia-one of the leading Portuguese media groups-and the Angolan satellite TV group SOCIP, needed to transport more than 100 SD and approximately 30 uncompressed HD signals over dark fibre from central Lisbon to Vendas Novas. Nevion’s Flashlink product family enabled scalable transport of all UPSTAR’s signals in one optical fibre without any amplification over the 100km between the two sites.
“Flashlink modules combine advanced DWDM (dense wavelength division multiplexing) and TDM (time-division multiplexing) to enable us to transmit a combination of HD and SD signals over a single fibre, while leaving room for additional wavelengths and significantly reducing our costs,” said Luis Henriques, technical director at UPSTAR. “Flashlink’s reliability, low-power and low-maintenance design were also key factors in our decision to choose Nevion.”
ZON’s challenge before choosing Nevion was to carry high quality signals over a distance close to 100km. This traditionally involved complicated and expensive compression transport solutions.
With the media group already an existing user of Flashlink, they decided to see if they could carry uncompressed signals over the full distance. This would provide a more suitable solution as they’d be able to continue using their existing products without incurring the additional costs of extra training for workers and other expensive infrastructure investments.
The scalable solution features multiple 4-channel SD-SDI/DVB-ASI time division de-multiplexers, 40-channel DWDM and numerous conversion modules. A browser-based graphical and SNMP monitoring system known as Multicon-GYDA offers comprehensive monitoring with remote firmware upgrades and customisable system overview for visual monitoring. A spare card set is also included for the most efficient main, secondary and third level back-up.
“Zon has been one of the major users of Flashlink optical solutions over the last few years and with their impressive optical network coverage they’re an example of a company that challenges technology to its maximum,” said Arne-Johan Martinsen, director of product marketing for the Flashlink product line. “We’re very proud to have met their requirements for this project and that our long-standing relationship has continued to grow from strength to strength.”
