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 10G SFP+ transceivers that operate over single-mode fiber and have a range of up to 10 kilometers. They are designed for 10 Gigabit Ethernet applications. However, there are subtle differences between these two modules, mostly centered around Cisco's branding and compatibility.

1. Cisco Optics Family:

   • SFP-10G-LR-S: This module belongs to the "S" or Standard optics family of Cisco, which is optimized for Cisco's Digital Optical Monitoring (DOM) capability.

   • SFP-10G-LR: This module is part of Cisco's base set of optics.

2. Compatibility:

   • SFP-10G-LR-S: It is typically associated with the Cisco S-Class optics, which are designed for use with Cisco switches in enterprise deployments. The "S" class is optimized for the needs of enterprise customers and may be priced more competitively.

   • SFP-10G-LR: This module is designed for broader compatibility across Cisco platforms and might be used in both service provider and enterprise networks.

3. Digital Optical Monitoring (DOM):

   • Both modules support DOM, which allows for real-time monitoring of parameters such as optical power, temperature, laser bias current, etc.

4. Price:

   • The "S" series (like SFP-10G-LR-S) is sometimes more affordable than the non-"S" series because it's tailored for specific use cases and might not have the broader compatibility of the non-"S" series.

5. Application/Use Case:

   • While both modules can be used in similar applications, the choice between them often comes down to the specific equipment they'll be used with and any associated compatibility requirements.

It's important to note that the actual capabilities, in terms of optical specifications, of the two modules are virtually identical. The main differences lie in their compatibility range and intended use scenarios. When deciding between these modules, it's crucial to check compatibility with the intended Cisco hardware and understand any specific features or optimizations that might be beneficial for the given deployment scenario.

What is cisco sfp 10g lr s?

The Cisco SFP-10G-LR-S is a member of the Cisco SFP+ transceiver module family. It's designed to operate with 10G Ethernet applications over single-mode fiber. Here are its specifics:

1. Type: It is an SFP+ (Small Form-Factor Pluggable Plus) module. SFP+ modules are an enhanced version of the SFP that support data rates up to 10 Gbps.

2. Speed: It supports a data rate of 10 Gbps, which is suitable for 10 Gigabit Ethernet applications.

3. Distance/Range: The "LR" in its name stands for "Long Range". It can transmit data up to 10 kilometers (km) over single-mode fiber.

4. Wavelength: Operates on a standard 1310 nm wavelength.

5. Compatibility: The "S" in "SFP-10G-LR-S" indicates that it belongs to the "S-Class" or Standard optics from Cisco, which is optimized for Cisco's Digital Optical Monitoring (DOM) capability. The S-Class optics are meant to be more economical and are optimized for the enterprise segment.

6. Digital Optical Monitoring (DOM): Supports DOM, allowing for real-time monitoring of parameters such as optical power, temperature, laser bias current, and others.

7. Fiber Type: Works with single-mode fiber (SMF).

8. Connector: Uses a standard LC duplex connector.

This module is typically used in enterprise settings with Cisco equipment that supports the SFP-10G-LR-S transceiver. As always, when considering such a module, it's essential to ensure compatibility with the intended hardware and understand the specific requirements of the deployment scenario.

What is cisco sfp 10g lr?

The Cisco SFP-10G-LR is also an SFP+ transceiver module, designed for 10 Gigabit Ethernet applications over single-mode fiber. It shares many characteristics with the SFP-10G-LR-S, but they belong to different product lines within Cisco's offerings. Here's an overview of the SFP-10G-LR:

1. Type: It's an SFP+ (Small Form-Factor Pluggable Plus) module. SFP+ modules are a version of the SFP that support data rates up to 10 Gbps.

2. Speed: It supports a data rate of 10 Gbps, making it suitable for 10 Gigabit Ethernet applications.

3. Distance/Range: The "LR" in its name stands for "Long Range". This module can transmit data up to 10 kilometers (km) over single-mode fiber.

4. Wavelength: It operates on a 1310 nm wavelength, standard for long-range modules.

5. Compatibility: While the SFP-10G-LR-S belongs to the "S-Class" or Standard optics line from Cisco, the SFP-10G-LR is part of Cisco's broader and more general portfolio of transceivers. It might offer additional compatibility or features, such as extended temperature range or broader compatibility across Cisco's product lines.

6. Digital Optical Monitoring (DOM): The SFP-10G-LR also supports DOM, which allows for real-time monitoring of various parameters like optical power, temperature, laser bias current, and more.

7. Fiber Type: It's designed to work with single-mode fiber (SMF).

8. Connector: Uses a standard LC duplex connector.

Both modules are similar in many aspects, but when choosing between them, factors such as product compatibility, specific features, and cost can come into play. It's always a good idea to consult Cisco's compatibility matrix or documentation (or reach out to Cisco directly) when making a selection to ensure the transceiver will work as expected with your equipment.
