Original SFP or original non-SFP

Original SFP or original non-SFP

When compatible optical modules (original etc.) first appeared on the market, there were many concerns and doubts about their compatibility and functionality. But after years, the leading compatible vendors have proven themselves with good quality and reputation. However, some people still cling to the myths of OEM receiver modules provided by major brand vendors and are hesitant to choose a compatible one. I’m sure as you read on, you’ll join the ranks of fans of good compatible vendors and their devices.

How are the main and other modules designed and produced?

It doesn’t matter if an optical module is original or original, sfp optical modules are all produced by the same method. And the usual module manufacturing companies are just a few, such as Avago, Finisar, Lumentum, etc.

The truth is that the manufacturers of the original optical module do not perform special clicks on the product. And all of them create standards based on MSA (Multiple Source Agreement), IEEE standard and European Union directives. A. But if the modules are the same, why is an OEM module so much more expensive than a non-original model?

Why is the original module so much more expensive?

Big brand companies like Cisco usually don’t make cables or sfp. They trust two or more manufacturers to make sfp modules for them and then rebrand the module and other related parts with their own logo.

Take 10GBASE-SR SFP+ as an example, the MSRP (Manufacturer’s Suggested Retail Price) is $20, but it is surprising that the customer should pay $100 when he receives the original module from the seller. If the customer buys directly without the original brand, he will only receive $16 from the original non-branded seller. How can this happen?

It doesn’t make sense for customers to pay an extra $94 just for an original logo on the module and cap, right? Therefore, the main vendors raise the issue of additional compatibility testing.

What do you know about testing the compatibility of the module with the devices?

Compatibility issue by original brand vendors after they add new code in standard module. There is a need for other original manufacturers to be able to adapt their products to original products. So that the main switches only work with modules that are coded correctly.

But that’s not what makes originals superior to non-originals. Third-party vendors can code the sfp modules by themselves and test each module on the original switch according to the latest software update and release (such as IOS, JunOS).

Can I use an original sfp module, for example, produced by Eriont, in original switches, such as Cisco?

Yes, the original products have great potential. In fact, good third-party vendors are able to produce multi-code compatible products that can support several different installed equipment. One of its advantages is that the service providers can provide a module that works with a larger number of products, for example, the Eriont production modules work with a variety of standard equipment in the market.

After considering the above questions, it is not difficult to conclude that good OEMs are better than the original module not only for cost but also in every aspect related to an affordable and high performance optical receiver.

Eriont is a producer of optical fiber modules compatible with different brands in Iran.
