XFP（10 Gigabit Small Form Factor Pluggable）是一种可热插拔的，独立于通信协议的光学收发器，通常工作波长是 850nm, 1310nm 或1550nm，用于10G bps的SONET/SDH，光纤信道，gigabit Ethernet，10 gigabit Ethernet和其他应用中，也包括 DWDM 链路。XFP包含类似于 SFF-8472 的数字诊断模块，但是进行了扩展，提供了健壮的管理工具。

XFI 电气接口规范是 XFP Multi Source Agreement 规范的一部分。

The XFP (10 Gigabit Small Form Factor Pluggable) is a standard for transceivers for high-speed computer network and telecommunication links that use optical fiber. It was defined by an industry group in 2002, along with its interface to other electrical components, which is called XFI.
