room air conditioning. Compared to the competition, the Flashlink line, which also features the lightest 2RU frame on the market, reduces power consumption by a dramatic 30-50%.

Greater distances for fewer regeneration points

Nevion’s 3G-SDI fibre transport solution announced last year is an example of advanced engineering leading to a simple advancement with far-reaching repercussions for the industry. While 3G distance capabilities of 30-33km is now standard, Nevion’s 3G-SDI EO and OE modules more than triple that distance. These modules transported pathological signals error-free over an impressive 120km of G.652 single mode fibre without any kind of electrical regeneration or optical amplification. This enables not only more efficient transport but also eliminates the need for additional equipment required at mid-span regeneration points. Thus, end users enjoy clear financial benefits in addition to increased efficiency. Moreover, the new 3G-SDI fibre converters include integrated distribution amplifiers and protection switches, eliminating the need for field upgrades from HD-SDI to 3G-SDI.

Taking legacy infrastructures into the future

The Ventura carrier-class product line provides perhaps the most sweeping example of design and engineering for broadcast network and equipment economy. Ventura products provide aggregation, conversion and transport solutions for compressed and uncompressed analogue and digital optical signals. The extensive selection of modules and space- efficient Ventura chassis enable customers to create flexible networks - networks that support a wide variety of formats, recover nimbly from signal interruptions, and provide long-lasting return on investment. In several instances, a single-rack Ventura solution provides equal functionality to competitors’ products requiring multiple racks. Most significantly, Ventura solutions maximise integration, flexibility and scalability, mitigating the need for large-scale network infrastructure replacement. The use of highly flexible state-of-the-art FPGAs also accelerates Nevion’s development cycle and allows customers to upgrade or add optional features simply by downloading new firmware, obviating the need for additional hardware upgrades.

75% of the globe with 18 hops

Recently a major broadcaster in the UK utilised Flashlink solutions to transport content from its London studio to a remote broadcasting centre. The dual optical circuits carry video and Ethernet traffic over CWDM/DWDM wavelengths, incorporating SD, HD and 3G HD capabilities, as well as 10 Gigabit Ethernet in both directions. The selected products also incorporate time division multiplexing capabilities to position four SD-SDI video signals onto one HD-SDI carrier for the most efficient transport and bandwidth maximisation. 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.

Nevion recently completed a successful live surgery HD video transmission from Trondheim, Norway to Daejeon, South Korea. Ventura solutions enabled the extremely high-quality, low-latency and error-free IP transmission through 18 connected networks on a more than 20,000-kilometre route across the globe. Without the standards-based technology of Nevion’s modular Ventura platform, which provided contribution grade audio and video over IP, the transmission would not have been possible. Once the transport

equipment was installed, tributaries assigned, and pathways configured, it was a plug-and-play solution, enabling live interactive video immediately upon power up. The ability to successfully traverse such a vast distance through switches from a range of vendors without a single adjustment or interruption surpassed even internal expectations and is due to the interoperability of Ventura’s standards-based technology. Assessing from a green perspective, savings can be attributed to fewer modules required, fewer hops needed saving equipment and personnel, not to mention the doors that this kind of transmission opens for long distance medical diagnosis and treatment. Of course the telemedicine application itself provides significant green benefits as it enables hospitals to deliver specialised treatment to distant locations without carbon- generating travel.

Interoperability through standards

The use of standards-based technology across product lines is critical to interoperability. While key on the product and application level, interoperability on a larger scale for video networking is even more significant. It enables the use of existing video networking infrastructures while adding network elements to keep pace with rapidly expanding needs and evolving technologies. The ability to add features and capabilities

incrementally as needed and stave off wholesale network replacement is an obvious environmental and cost benefit.

Green practices are wins for the industry

Designing and implementing green practices that save resources, money and energy is easier said than done to be sure. But it is in everyone’s best interest to push for these solutions, regardless of your position in the broadcast industry. Some green practices, products and policies bear immediate fruit, such as reduced power needs while for others it may take years to see the results. But the effects are cumulative, and in the end are wins for all of us, both as broadcast professionals and citizens of the world.
