SFF
The small form-factor (SFF) is a compact optical
transceiver used in optical communications for both telecommunication and data
communications applications. It is a popular industry format supported by several fiber
optic component vendors. SFF transceivers are designed to support SONET/SDH,
Gigabit Ethernet, Fibre Channel, and other communications standards
SFF transceivers are available with a variety of different
transmitter and receiver types, allowing users to select the appropriate
transceiver for each link to provide the required optical reach over the available
optical fiber type (e.g. multi-mode fiber or single-mode fiber). Optical SFP
modules are commonly available in four different categories: 850 nm (SX), 1310
nm (LX), 1550 nm (ZX), and DWDM/CWDM.
SFP transceivers are commercially available with capability for datarates up to 4.25 Gbit/s.
