Nowadays,
Fiber optic transceiver is popular with people around the world,
especially the SFP and SFP+ transceivers which are the most widely used
modules for both telecommunication and data communications applications.
They have small sizes and are available with various types, that allows
users to select the appropriate one to provide the required optical
reach over single-mode fiber or multimode fiber. Since they are of great
importance in the network, manufacturers have designed various types of
SFP and SFP+ modules to satisfy different demands, including compatible
SFP and SFP+ transceivers. Nowadays people are apt to use the
compatible SFP/SFP+ transceivers instead of the original ones, do you
know the reasons of this? This passage tends to talk about this subject
and gives you a basic understanding of compatible SFP and SFP+ modules.
Think twice Before Choosing SFP and SFP+ Transceivers
When
you need a new SFP or SFP+ transceivers, you should take manufacturer
compatible modules into consideration. For example, if you saw a
manufacturer SFP or SFP+ modules side-by-side with a first-party OEM
modules without the label, I bet that you probably wouldn’t be able to
tell the difference between them. Because they are essentially the same,
that is to say that the first-party compatible SFP or SFP+ transceivers
contain the same opto-electronics and is provided by the same
distributors as the higher-priced SFP or SFP+ modules you would buy from
companies, like Cisco, Finisar or Brocade, etc.
Why Should We Use Compatible SFP and SFP+?
When
we purchase products, we’ll take many aspects into consideration, such
as the price, functions, capability, etc. The following part lists two
main reasons why we choose compatible SFP and SFP+.
Cost
With
the basic information we have talked about SFP and SFP+ above, there is
no doubt that SFP and SFP+ are indispensable components in network
communication, but it is really a headache that costs for transceiver
modules are keeping rising for users. If you choose Cisco, Finisar, and
Dell or any other brands of transceivers, you will find that they are
too expensive for us, especially for those who are deficient in capital.
However, on the market, compatible SFP and SFP+ are at least the half
price of the original one. For example, a Cisco SFP-10G-SR compatible
10GBase-SR SFP+ transceiver is only 16 dollars.
Compatibility
As
we all know, each transceiver module is unique and holds its own
information in EEPROM, so do SFP and SFP+ transceivers. And this memory
is coded with specific identifiers such as pert numbers and manufacturer
details. When the module is installed, the host device then checks the
memory for the correct information to confirm compatibility. Compatible
SFP and SFP+ contain the same production technology as the original
brands. In other words, they have the same hardware. Take Finisar SFP as
an example, a Finisar FTLF1318P2BTL is compatible with the original
Finisar SFP transceiver, having all the same features as the original
one does, and it is also supported on a wide range of Finisar equipment.
Conclusion
With
increasing demand for transceivers, compatible SFP and SFP+ with lower
cost and high compatibility are absolutely perfect choices for most
users. But keep in mind that you should have a firmware check for
compatibility before installing, or the modules can’t work in good
condition. FS.COM always strives to provide optical products and has
earned a good reputation among our customers. You could find all kinds
of transceivers here, such as 10G SFP+, 100Base SFP, XFP, and so on. And
we offer varieties of SFP and SFP+ transceivers which are fully
compatible with major brands at very lower price. In addition, we
promise every compatible product here is individually tested, walks
through the testing challenges and 100% compatibility.
