This brings us to a new connector system recently adopted for Category 7, or ISO Class F, service. The Siemon Company offers the TERA™ connector to support 600 MHz and above. See Figure 6. The TERA connection system provides significant isolation between data pairs with radically different construction. Crosstalk budget greatly exceeds that of Category 6, or Class E, service. The TERA connector will support us on into 10 gigabit Ethernet.
