SFP 10G SR vs SFP 10G SR S ：What's the difference?

The difference between the SFP-10G-SR and SFP-10G-SR-S modules primarily revolves around their operational environment and temperature range specifications:

1. Temperature Range: The key difference usually lies in their supported temperature ranges. The SFP-10G-SR typically has a commercial temperature range, commonly from 0°C to 70°C. The SFP-10G-SR-S, on the other hand, may have an extended temperature range, making it suitable for more demanding environments.

2. Application Environment: The SFP-10G-SR-S is often designed for more robust applications, potentially suitable for industrial environments where temperature fluctuations are more extreme.

3. Compliance and Certification: There may be differences in compliance and certification standards between the two modules. The SFP-10G-SR-S might meet additional standards or certifications required for certain special applications or industries.

4. Cost: Due to the enhanced specifications, the SFP-10G-SR-S might come at a slightly higher cost compared to the standard SFP-10G-SR.

5. Other Specifications: In terms of basic functionality, like data rate, transmission distance, and the type of fiber used (usually multimode for up to 300 meters), both modules are generally similar. They are designed for 10G Ethernet applications and use an LC duplex connector.

It's important to choose the module that best fits your specific environmental conditions and network requirements. For standard data center environments, an SFP-10G-SR is often sufficient. In contrast, for industrial settings or outdoor applications with more extreme temperature ranges, an SFP-10G-SR-S might be more appropriate.

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.
