The SFP *0GB|SFP+|SFP-plus is the enhanced small form-factor
pluggable. It has the same shape as a 1G SFP but will support data
rates up to *0 Gbit/s. On May *9, ***0 the specs were first
published. SFP *0GB transceivers are interchangeable with SFP
transceivers and can be used in the same cages as SFP transceivers.
For *0 Gbps applications, SFP *0GB Optics have a smaller footprint
and lower power consumption than XFP transceivers. The electrical
interface to the host board for SFP and SFP+ modules is a serial
interface. The SFP+ is also called SFP *0GB to avoid confusion with
the 1G version. It will support 8 Gbit/s on Fibre Channel and *0
Gbit/s on Gigabit Ethernet and Optical Transport Network standard
OTU2. It is a popular industry format because of the small shape
(you can fit *8 pieces in 1RU). Furthermore, you can use the ports
in 1G and *0G modes. The SFP *0GB comes in 4 different versions:
SX, LX, EX and ZX. The SX version will work on Multi Mode fiber,
the LX, EX and ZX will work only on Single Mode fiber. The LX will
cover a maximum range of *0km, the EX of *0km, with the ZX reaching
up to *0km. The optics always have a Tx side (sending laser) and a
Rx side (receiver). The difference between the sending power (in
dB) and the receiving power (in dB) is called the power budget and
will determine the distance an optic can cover, where also the
laser light (in nanometers) has an important role. In ***0, the ZR
(*0km) CWDM and DWDM SFP *0GB optics became available. The SFP *0G
is available in SFP+, CWM SFP *0Gb, DWDM SFP+ *0Gb. POFLink,
however, can offer you the whole CWDM DWDM spectrum for SFP *0GB.
The SFP *0GB is also available as a BIDI optic, which has only 1 LC
plus and will work on 1 single strand of Single Mode fiber. The
buyers for SFP+ are typically storage vendors and private
datacenter operators, such as Google, Amazon, Yahoo, Facebook.
Other customers with large datacenter requirements may make the
same decision and move forward with the SFP *0GB form factor as the
technology becomes more prominent.
