Ultra-low Loss, Highly Heat Resistant Circuit Board Materials
Designed for high-speed communication network equipment such as routers and switches, MEGTRON 8 multi-layer circuit board material features the industry’s lowest transmission loss. This contributes to larger capacity and higher-speed data communication and may reduce power consumption because of the lower transmission loss.
The MEGTRON 8 family supports 800GbE used for next-generation high-speed communication technology and offers about a 30% improvement in transmission loss compared to MEGTRON 7.
