Category: - Principle: Newtec - Product: Clean Channel Technology - Available from Melcom


Melcom supply Newtec's Clean Channel Technology

Clean Channel Technology™ further improves satellite efficiency by up to 15% compared to the current DVB-S2 standard for IP trunking, backhauling and government networks but also broadcast contribution. Newtec’s customers will be able to immediately benefit from Clean Channel Technology™, as it is available as a software field upgrade for existing Newtec equipment.

•    Increase efficiency up to 15%
•    Future Proof for upcoming DVB standards
•    Upgrade for existing Newtec equipment
•    Available as option on new equipment
•    Advanced filter technology
•    Allows optimum carrier spacing of several carriers
•    5%, 10% and 15% Roll-off options
•    For operations with single carrier, multiple carriers and shared transponders
•    Do more with available bandwidth or cut OPEX costs

A first step in the Clean Channel Technology™ is applying a smaller Roll-Off (RO) percentage than currently used in the DVB-S2 standard. In the DVB-S2 standard the 20% and 25% Roll-Off percentages are common. Which basically means that these percentages need to be added to the desired bandwidth over satellite. Reducing these Roll-Offs to 5%, 10% and 15% results in a direct gain in bandwidth. Looking at the spectral image when implementing smaller Roll-Offs the slope of the carrier becomes steeper compared to DVB-S2 but still fits nicely in the allocated bandwidth.

The second step deals with noise levels (side lobes) on both sides of the carrier. These side lobes prevent putting satellite carriers close to each other. Applying advanced filter solutions such as Clean Channel Technology™ have immediate effect on bandwidth savings as the spacing between carriers can be put as close as 1,05 times their symbol rates.
