Introduction of the optics Cisco S-Class e.g. SFP-10G-SR-S was introduced in 2014. In terms of qualification among the S and Non-S-categories, you can’t find any noticeable distinction in Cisco’s authorized data sheet. Therefore, about this sequence of optics, most of the people are still unclear. Nevertheless, you will realize that Non S-Class are more expensive as compared to the S-Class optics e.g. the price of SFP-10G-SR is near $220 which is greater than the price of SFP-10-SR-S Cisco module.
On the other hand, SFP-10G-LR is of higher cost than SFP-10G-LR-S. Therefore, what makes them different? We will take this topic in consideration today.
Characteristics of Cisco-S-Class module:
S-Class optics is formed for data center 40 and 10G implementations and for enterprise in accordance with Cisco. For the implementations, this new activation of S-class optics does not have useless characteristics and most importantly in terms of cost, it is more appealing. Therefore economically, S-Class optic is of low value than Non-S Class. It was declared by Cisco in the meantime that the accessibility of S-Class optics will only be in data center implementations and enterprise. It is true that “common reaches” and “useless characteristics” put the consumers into problem.
Various users who are pleased with Cisco optics, suitable price of S-Class Optics appeals to them. The consumers ask a number of questions simultaneously e.g. when should the S-Class optics be utilized? What are the useless characteristics? It is sad to say that for this purpose, there is still no particular documentation. Surprisingly, we don’t have any clue from the datasheet too. But we are giving you some knowledge about S-Class optics which can support you to get realized more about it. That’s why there is no need to be dissatisfied.
S-Class is no WAN-PHY or OTN, it is just Ethernet and along with, for S-Class category it has no TAA acquiescence. Furthermore, non S-Class optics have particular temperature ranges of their own. So, S-Class optics are of low cost and are better for you, in case if you are an advertiser or data center conditions that does not demand any resilience to temperature, specific long distance or other characteristics of significance. As a matter of fact, we can see some hidden contradiction. But of course, when Cisco presented the S-Class, the difference is not the principal point to discuss. The principal selling concern is of low cost and as far compatibility is concerned, there is no need to be worried about it.
Which One is the Best Option to Purchase SFP-10G-SR-S or SFP-10G-SR?
Nevertheless, according to the confidence of Cisco, Cisco S-Class optics is in demand with the extending progress of third party compatible optics. For example, from a fiber store, at the cost of 18 dollars you may give favor to purchase SFP-10G-SR Cisco compatible module instead of to purchase SFP-10G-SR-S class Cisco optics in price of about 500 dollars. As per price difference, it is impossible to believe that you can make pleasure by enjoying the similar performance and uses which SFP-10G-SR (Cisco) is having. S-Class optics which is the requirement of data center implementations on the common reaches should be the perfect option for you, if you are a true Cisco user.
