Bel Stewart offers the 10GBASE-T (10 Gigabit over twisted-pair) integrated connector module
The 10GBASE-T meets PCIe mechanical requirements and supports the latest 10GBASE-T physical layer device (PHY) technology and applications. It also meets or exceeds IEEE 803.an requirements and is tuned to have flat insertion-loss curves and excellent return-loss performance at high frequencies. The PHY-side return-loss up to 400 MHz meets or exceeds return loss requirements. A low insertion loss over the 1 MHz to 400 MHz band allows for longer cable reach. This new platform is designed to help meet tough EMC system requirements such as FCC Part 15 class B.
