XFP
What is XFP
An XFP is a hot-swappable, protocol-independent optical transceiver, typically operating at 850nm, 1310nm or 1550nm, for 10 Gigabit per second SONET/SDH, Fibre Channel, gigabit Ethernet, 10 gigabit Ethernet and other applications, including DWDM links. It is a 10 Gbit hot pluggable module converting serial electrical signals to external serial optical or electrical signals. It includes digital diagnostics similar to SFF-8472 but more extensive, that provides a robust management tool.
XFP was developed by the XFP Multi Source Agreement Group. The module design and the volume of production are expected to enable very low cost 10 Gb/s solutions.
XFP Applications:
- OC192/STM-64 9.95 Gb/s
- 10 Gigabit FC 10.5 Gb/s
- G.709 10.7 Gb/s
- 10 Gigabit Ethernet 10.3 Gb/s
- Smaller space and lower cost alternative to parallel-optics VSR.
XFP Dimensions
The physical dimensions of the XFP are slightly larger than the standard SFP. One of the reasons for the increase in size is to allow for on board heat sinks for greater cooling.
XFP dimensions are:
- Height: 0.33 inches (8.5 mm)
- Width: 0.72 inches (18.3 mm)
- Depth: 3.1 inches (78 mm)
XFP Value Propositions
- Protocol Agnostic - "any application, any rate".
- Allows 16 XCVRs on a typical 19" rack with 23mm pitch density.
- Single footprint for all links.
- Less than 1/3 the power and size of an MSA with parallel interface.
- Hot plugable.
