Cisco sfp-10g-lr-s vs sfp-10g-lr : What's the difference?

The "Cisco SFP-10G-LR-S" and "Cisco SFP-10G-LR" are both 10-Gigabit SFP+ transceivers that operate with single-mode fiber. However, they belong to different SFP product families, with the "S" in "SFP-10G-LR-S" standing for "S-Class". Here are the main differences between these two:

1. Targeted Use Cases:

   • SFP-10G-LR-S (S-Class): Cisco's S-Class transceivers are designed for enterprise and data center 10G and 40G applications, offering a more cost-effective solution. They're best suited for intra-data center use, where distances between connections are shorter.

   • SFP-10G-LR: This module is part of Cisco's standard SFP+ lineup and is suitable for a broader set of applications, including enterprise networking and metro Ethernet links.

2. Temperature Range:

   • SFP-10G-LR-S (S-Class): These typically have a commercial temperature range (0 to 70°C).

   • SFP-10G-LR: These might offer an extended or industrial temperature range, which could be more suitable for outdoor or more challenging environments.

3. Other Features:

   • Features like Digital Optical Monitoring (DOM) support might be present in the standard lineup (SFP-10G-LR) but might not be available in the S-Class version, or there might be differences in the level of support for this feature between the two versions.

4. Cost:

   • Generally, the S-Class modules (like SFP-10G-LR-S) are more cost-effective than the regular ones (like SFP-10G-LR) because they are optimized for specific use cases like intra-data center connections.

5. Interoperability and Compatibility:

   • Both transceivers should be compatible with any Cisco equipment that supports 10G SFP+ modules, but always check the compatibility matrices or device datasheets to ensure proper operation.

6. Wavelength, Distance, and Fiber:

   • For both modules, the typical wavelength is 1310 nm, and they can support a link length of 10 kilometers on standard single-mode fiber (SMF).

When choosing between the two, consider the intended application, environment, required features, and budget constraints. Always refer to Cisco's official documentation and datasheets for a detailed comparison and compatibility checks.

What does it mean to distinguish Cisco sfp-10g-lr-s from Cisco sfp-10g-lr?

What is Cisco sfp-10g-lr-s?

The "Cisco SFP-10G-LR-S" is a type of SFP+ (Small Form-Factor Pluggable Plus) transceiver module that's designed for 10 Gigabit Ethernet applications. Specifically, this module is part of Cisco's "S-Class" lineup of optical transceivers, which are optimized for cost-effective enterprise and data center applications.

Here's a basic rundown of the Cisco SFP-10G-LR-S module:

1. Operational Mode: This module is designed to work with single-mode fiber (SMF), which is the type of optical fiber that supports longer distances compared to multimode fiber.

2. Wavelength: The module operates at a wavelength of 1310 nm.

3. Distance/Range: It can support a link length of up to 10 kilometers (km) on standard single-mode fiber.

4. Connector Type: It uses the LC/PC connector type, which is standard for many SFP and SFP+ modules.

5. Operational Temperature: As an S-Class module, its operational temperature typically ranges from 0 to 70°C, suitable for most indoor environments.

6. Applications: Cisco's S-Class transceivers are designed primarily for intra-data center and enterprise applications. They are ideal for shorter, in-building connections where extended temperature ranges and other advanced features aren't necessary.

7. Cost-Effectiveness: The "S" in "SFP-10G-LR-S" denotes its position as a more budget-friendly option within Cisco's product lineup. It's optimized for specific use cases, offering a cost advantage over other modules that are designed for a broader set of applications.

8. Compatibility: The module is designed to be compatible with a range of Cisco switches, routers, and other network devices that support 10G SFP+ modules. Always consult with Cisco's compatibility matrices or product datasheets to ensure it works with your specific device model.

9. Digital Optical Monitoring (DOM): The SFP-10G-LR-S module might also support DOM, allowing for real-time monitoring of transceiver operational parameters such as temperature, optical power levels (both transmitted and received), and more.

When choosing a transceiver for deployment, always consider the specific requirements of your networking environment, the distances between linked devices, and the fiber type installed in your facility.

What is Cisco sfp-10g-lr ?
