Yes, XFP optical modules are standardized for 10 Gigabit per second (10G) operation.

XFP (10 Gigabit Small Form-Factor Pluggable) modules were specifically developed to support high-speed network and telecommunication links at 10 Gbps . They are protocol-independent and can be used for 10G Ethernet, 10G Fibre Channel, OC-192/STM-64 SONET/SDH, and 10G Optical Transport Network (OTN) applications . The XFP standard includes a 10G electrical interface called XFI, which provides a single-lane 10.3125 Gbit/s connection using 64B/66B encoding . XFP modules are available in multiple optical variants, operating at 850 nm, 1310 nm, or 1550 nm wavelengths, and can support transmission distances from short-reach multimode fiber links to long-distance single-mode fiber connections . They are hot-swappable and designed to provide flexibility in network deployment, including digital diagnostics for monitoring performance . While XFP modules are all designed for 10G speeds, they differ in reach, fiber type, and protocol support. For example, some XFPs are optimized for short-reach multimode Ethernet, while others are intended for long-haul single-mode links or SONET/SDH transport . This means that although the speed is consistently 10 Gbps, the application and optical characteristics vary depending on the specific module. In summary, all XFP optical modules operate at 10 Gigabit speeds, but their optical reach, wavelength, and supported protocols can differ, making it important to select the appropriate XFP type for your network requirements .
