[Satellite TODAY 08-30-12] Work Microwave has unveiled a new digital filter with a roll-off factor of 5 percent as part of its DVB-S2 modem and modulator portfolio, the company announced Aug. 30.
Work Microwave said the filter aims to allow corporate network and Internet service providers, government networks and satellite operators to maximize the bandwidth of their DVB-S2 networks and more efficiently deliver a high-quality of service utilizing the unit’s roll-off feature. The main purpose of roll-off technology is to minimize unused bandwidth space between satellite carriers, enabling an operator to support a wider carrier or additional carriers.
“Satellite operators have only recently allowed a roll-off smaller than the 20 percent to 35 percent that DVB-S2 allows," Work Microwave Senior Engineer Joerg Rockstroh said in a statement. “Leveraging our more than 25 years of experience creating cutting-edge communications technologies, Work Microwave quickly developed a much smaller roll-off of 5 percent, enabling service providers to maximize the size of their carriers in order to optimize bandwidth use.”
