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 patented riding heat sink technology for thermal dissipation. The heat sink is mounted to the cage using a clip, which provides a load to maintain contact between heat sink and module. Heat sinks are available in three heights, and custom heat sinks are possible. This heat sink technology has extended to SFP and QSFP applications. The XFP connector is a 30 position PT connector, using the same design as used in SFP for established performance and reliability.
