SFP+ Transceiver technical info and data sheets

The enhanced small form-factor pluggable (SFP+) is an enhanced version of the SFP that supports data rates up to 10 Gbit/s. The SFP+ specification was first published on May 9, 2006, and version 4.1 published on July 6, 2009. SFP+ supports 8 Gbit/s Fibre Channel, 10 Gigabit Ethernet and Optical Transport Network standard OTU2. It is a popular industry format supported by many network component vendors.

In comparison to earlier XENPAK or XFP modules, SFP+ modules leave more circuitry to be implemented on the host board instead of inside the module.

SFP+ also introduces Direct Attach for connecting two SFP+ ports without dedicated transceivers.

SFP transceivers are available with a variety of 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 several different categories:
for multi-mode fiber, with black or beige extraction lever SX - 850 nm, for a maximum of 550 m at 1.25 Gbit/s (Gigabit Ethernet) or 150m at 4.25 Gbit/s (Fibre Channel)

for single-mode fiber, with blue extraction lever LX - 1310 nm, for distances up to 10 km
EX - 1310 nm, for distances up to 40 km
ZX - 1550 nm, for distances up to 80 km, with green extraction lever
EZX - 1550 nm, for distances up to 120 km
BX - 1490 nm/1310 nm, Single Fiber Bi-Directional Gigabit SFP Transceivers, paired as BS-U and BS-D for Uplink and Downlink respectively, also for distances up to 10 km. Variations of bidirectional SFPs are also manufactured which use 1550 nm in one direction.
1550 nm 40 km (XD), 80 km (ZX), 120 km (EX or EZX)
