SFP 10g sr s vs SFP 10g sr : What's the difference?

According to Cisco, S-class optics are intended for enterprise and data center 10G and 40G applications This new set of optics does not display several unnecessary features for these applications, bringing about a more attractive price. That explains why SFP-10G-SR-S price is lower than SFP-10G-SR price. Except the price, there are some other differences. SFP-10G-SR-S optics aren’t TAA certified. However, the non-S-class optics such as SFP-10G-SR are all compliant to TAA. SFP-10G-SR-S optics only have COM (Commercial temperature range: 0~70℃). However, the temperature range of SFP-10G-SR can be EXT (Extended temperature range: -5~85℃), IND (Industrial temperature range: -40~85℃) and Storage temperature range (-40~85℃).
In terms of protocols, SFP-10G-SR-S optics use Ethernet only, they cannot use OTN (Optical Transport Network) or WAN-PHY (Wide Area Network Physics). Furthermore, SFP-10G-SR-S optics just have 10G and 40G applications so far which is specified for 10G and 40G enterprise and data center. Thus, if you don’t need any special features like extra tolerance for temperature, S-Class optics can save you a considerable amount of money.
 
1.Manufacturer's Designation: The additional "-S" in "SFP-10G-SR-S" often indicates a specific manufacturer's product line or series. For instance, in the context of Cisco, the "-S" typically designates modules in their S-Class optical transceivers, which are optimized for high-speed short-range data center interconnects.
2.Optimized for Specific Applications: The S-Class, for instance, is optimized for use in data center applications and might not support all the features of their non-S counterparts or might lack certain certifications, leading to a reduced cost.
3.Cost: Given the specific application-focused nature of the "-S" designated modules, they might come at a lower price point than their more general-purpose counterparts.
4.Compatibility and Supported Features: The "-S" modules might not support all the features as the non-S ones. They might be optimized for specific platforms or use-cases.
It's essential to consult the manufacturer's datasheet or technical specifications for the exact differences between these modules, as the differences might vary based on the manufacturer and the context in which these designations are used.
 

What do sfp 10g sr s and sfp 10g sr respectively represent?

 
 
 

What is sfp 10g sr s？

Like as SFP-10G-SR, SFP-10G-SR-S is typically used as the part number of Cisco S-Class 10GBASE-SR SFP+ Module. The main difference between SFP-10G-SR and SFP-10G-SR-S is the different features. According to Cisco, S-class optics is an inexpensive option designed for enterprise and data center 10G and 40G applications. The S class is suitable for the below environment: in non-temperature controlled environments, e.g. rugged/ industrial (RGD), Optics plugged on platforms that require extended operating temperature range (EXT), TAA compliance.
 
The "SFP-10G-SR-S" is a specific kind of SFP+ transceiver module. Let's break down its designation:
· SFP: Stands for "Small Form-factor Pluggable." It's a standard format for network interface cards, but in this context, it's used colloquially to refer to the newer, faster SFP+ standard.
· 10G: This indicates that the transceiver is designed for 10 Gigabits per second (Gbps) data rates.
· SR: Stands for "Short Range." It means this transceiver is intended for short-range signal transmission, typically over multi-mode fiber. SR modules often have a range up to 300 meters, depending on the type and quality of the fiber.
· S: This often designates a special or "enhanced" version of the module. For Cisco, which is a prominent vendor of networking equipment, the "-S" indicates that the module is part of their "S-Class" of optical transceivers. These are optimized for high-bandwidth data center use and might have features like lower power consumption or better performance in high-temperature environments, but they could lack some advanced diagnostic features found in non-S-Class versions.
In essence, the "SFP-10G-SR-S" is an SFP+ module designed for 10 Gbps short-range transmissions over multi-mode fiber and is part of Cisco's S-Class series, optimized for data center applications.
 

What is sfp 10g sr?

SFP-10G-SR is typically used as a part number by Cisco. According to Cisco, it is 10GBASE-SR SFP+ Module supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade Multimode Fiber (MMF). SFP-10G-SR is a hot-swappable input/output device which allows a 10 Gigabit Ethernet port to link with a fiber optic network. SFP-10G-SR is also used as the replacement model of compatible 10GBase-SR SFP+ Transceiver with the same function and performance supplied by many other 3rd party suppliers and stores.
 
· The "SFP-10G-SR" is an SFP+ transceiver module. Here's a breakdown of its designation:
· SFP: Stands for "Small Form-factor Pluggable." In this context, it's used to refer to the SFP+ standard, which is an enhanced version of the original SFP standard.
· 10G: This indicates that the transceiver is designed for 10 Gigabits per second (Gbps) data rates.
· SR: Stands for "Short Range." This means that this transceiver is intended for short-range signal transmission, typically using multi-mode fiber. SR modules are designed to work over short distances and are often used within data centers, buildings, or campus environments. For the SFP-10G-SR, the typical range is up to 300 meters depending on the type and quality of the fiber used.
In summary, the "SFP-10G-SR" is an SFP+ module designed for 10 Gbps short-range transmissions over multi-mode fiber, commonly used in data centers and similar environments.
 
 

SFP-10G-SR-S vs SFP-10G-SR, Which Will You Choose?

Although SFP-10G-SR-S vs SFP-10G-SR, they share identical specification, there still are some minor difference. In most cases, SFP-10G-SR-S optics are recommended for 10G and 40G applications due to its low cost. both SFP-10G-SR price and SFP-10G-SR-S price is relatively lower according to the above chart, and they also enjoy good quality. If you need any third-party optical modules or fiber optic cables, give FS.COM a shot.
 

Cisco 10G S-Class vs Non-S-Class Module Overviews

Cisco has introduced four kinds of 10G S-Class modules, including SFP-10G-SR-S, SFP-10G-LR-S, SFP-10G-ER-S, SFP-10G-ZR-S, which are all named with an “S”. Abandoning some “unnecessary features”, these optics are especially designed for enterprises, data centers and other environments without special requirements for temperature. While non-S-Class optics have more types, such as SFP-10G-SR, SFP-10G-LR, SFP-10G-ER, SFP-10G-ZR etc. Sharing identical specification, Cisco S-Class modules seem to have no differences with non-S-Class modules.
