XFP was developed to provide 10Gb/s serial links for a wide range of applications including standards such as OC192/STM-64, G.709, and 10 Gigabit Ethernet.  The cage/plug interface features an intuitive latch system, gasketing features for excellent EMI containment, and was the first pluggable interface to incorporate Tyco Electronics’ patented riding heatsink technology for thermal dissipation.  Tyco Electronics offers active XFP copper cables up to 5M in length and passive cables up to 1M.
