The BiPass solution has the opportunity to save designers money as well as be a key enabler as we move forward with 112Gbps PAM-4 implementations.\u201d <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"> The BiPass solution, allows designers to bypass the lossy printed circuit board by utilising Temp-Flex high-speed twinax. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because of this, they can achieve lower insertion loss when going from an ASIC in a switch or a router to another server within a rack.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Advances in heat sink technologies are enabling highly efficient, reliable and resilient thermal management strategies to support higher density in both copper and optical connectivity.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">From a future perspective, this great signal integrity performance and low insertion loss capability allows designers to use passive copper throughout the entire design.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cAs demand for faster data rates grow, data centre technology is evolving quickly, and thermal management technology must keep up. The BiPass solution allows for better temperature control of a system using advanced materials, the latest tools and cutting-edge technologies without compromising performance,\u201d adds Kapuscinski.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Molex highlights its new BiPass thermal management configuration cooling QSFP-DD modules up to 20W with a 15\u02daC change from the ambient temperature.
